Opis:
Autorka omawia kolejne etapy przetwarzania i wizualizacji danych, które pokonuje kartograf opracowujący mapę, by dojść do form prezentacji. Rozważania w pierwszej części artykułu są oparte na zaproponowanym przez autorkę schemacie przejścia od danych do prezentacji kartograficznej. W drugiej części - z rozważań tych wyprowadzone zostaną poszczególne formy prezentacji kartograficznej.
In contemporary cartography, computer has bacome a basic tool for map elaboration. Cartographic metodology is an important branch of cartography, into which computers have made a dynamic entrance. It lists basic rules of transformation and graphical presentation of data. This article attempts to look at the methods of cartographic presentation through the eyes of the map's editor and establish conditions, which have to be fulfilled to transform a set of data into a properly prepared map. "Cartographic presentation method" - meaning the process is differentiated from "cartographic presentation form" - meaning the result of this process, i.e. the map. The article follows the process of transition from data to cartographic presentation and establishes features, which allow a graphic picture to be called a cartographic presentation form. Data is the starting point of any cartographic presentation. in the process leading from data to presentation (fig.1) there are two separate stages: data preparation (transformation) and data visualization. At the stage of transformation the map editor can, according to the map's purpose, modify source data by changing measurement levels, data reference (point, linear, surface), its character (relative data, absolute data) and way of treating data (continuous, in intervals). Visualization is the next step from data to a cartographic presentation form. At this stage transformed data become a graphic picture. It happens after considering the following presentation elements: -graphical symbol, -visual variables, -graphical rendering, -correctly constructed legend. Correct and logical transfer from data through cartographic presentation method leads to a map. The effects of this transfer are graphic picture, i.e. cartographic presentation forms. Here it should be considered, if every set of data can be freely transformed and visualized and if such procedure would lead directly to a correct and aesy to use cartographic presentation form.

Opis:
The author discuss effectiveness of cartographic presentations. The article includes opinions of cartographers regarding effectiveness, readability and efficiency of a map. It reminds the principles of map graphic design in order to verify them using examples of small-scale thematic maps. The following questions have been asked: Is the map effective? Why is the map effective? How do cartographic presentation methods affect effectiveness of the cartographic message? What else can influence effectiveness of a map? Each graphic presentation should be effective, as its purpose is to complete written word, draw the recipients’ attention, make text more readable, expose the most important information. Such a significant role of graphics results in the fact that graphic presentations (maps, diagrams) require proper preparation. Users need to have a chance to understand the graphics language in order to draw correct conclusions about the presented phenomenon. Graphics should demonstrate the most important elements, some tendencies, and directions of changes. It should generalize and present a given subject from a slightly different perspective. There are numerous examples of well-edited and poorly edited small-scale thematic maps. They include maps, which are impossible to interpret correctly. They are burdened with methodological defects and they cannot fulfill their task. Cartography practice indicates that the principles related to graphic design of cartographic presentation are frequently omitted during the process of developing small-scale thematic maps used – among others – in the press and on the Internet. The purpose of such presentations is to quickly interpret them. On such maps editors’ problems with the selection of an appropriate symbol and graphic variable (fig. 1A, 9B) are visible. Sometimes they use symbols which are not sufficiently distinguishable nor demonstrative (fig. 11), it does not increase their readability. Sometime authors try too hard to reflect presented phenomenon and therefore the map becomes more difficult to interpret (fig. 4A,B). The lack of graphic sense resulting in the lack of graphic balance and aesthetics constitutes a weak point of numerous cartographic presentations (fig. 13). Effectiveness of cartographic presentations consists of knowledge and skills of the map editor, as well as the recipients’ perception capabilities and their readiness to read and interpret maps. The qualifications of the map editor should include methodological qualifications supported by the knowledge of the principles for cartographic symbol design, as well as relevant technical qualifications, which allow to properly use the tools to edit a map. Maps facilitate the understanding of texts they accompany and they present relationships between phenomenon better than texts, appealing to the senses.

W artykule przedstawiono różne możliwości zastosowania w kartografii trójkąta Osanna, zwanego również wykresem trójkątnym. Po krótkim zarysowaniu historii tego sposobu prezentacji, szczegółowo omówiono jego właściwości oraz zasady konstrukcji. Pokazano różne sposoby czytania i interpretacji trójkąta, a także kartograficzne przykłady jego zastosowania.
Osanna Triangle, also known as a triangular diagram, is a specific method of data presentation, used in statistics and socio-economic cartography to present phenomena of three-fold structure. This type of diagram presents which part of the whole is composed by particular elements, what the proportion of those elements is and how similar elements in two or more various entities compare. It is used as an independent presentation form as well as a legend of thematic maps. The term 'Osanna Triangle' comes from a name of a German mineralogist, Alfred Karl Osanna (1859-1923), who analyzed minerals according to their atomic and particle contents. The chemical classification of rocks, which he prepared, was presented on triangular diagrams. Osanna Triagle is a diagram of relations of three variables placed in a system of three coordinates. The location of each point within the triangle is determined by three coordinates, read at its sides, on heights led from its angles or on lines of the grid (fig. 2). Proper interpretation of the diagram bases on the understanding of significance of points' placement within the triangle. Often the triangle is divided into smaller units (triangles, rectangles) in order to establish areas where points with similar features occur (fig. 4). This diagram can be used to present the structure of a given statistical set and also conclusions about the whole set (fig. 5). Also, it can show the dynamics of a phenomenon through changing value of particular elements of the structure in time (fig. 6). Osanna Triangle is frequently used as an explanation, map legend, most often related to a choropleth presentation. Basing on a triangular diagram one can conclude about the distribution of phenomenon's value and determine choropleth classes. Application of an unorthodox triangular set of coordinates, to which we are not used, makes the perception of Osanna Triangle rather difficult. Perhaps this is why this method of data presentation is not commonly used.

Podstawą rozważań w tej części artykułu są wprowadzone poprzednio pojęcia metody i formy prezentacji kartograficznej. Autorka omawia kryteria wydzielania poszczególnych metod prezentacji i podejmuje próbę ich klasyfikacji. Wykorzystując zaproponowany w pierwszej części artykułu schemat przejścia od danych do prezentacji autorka wyprowadza z niego poszczególne formy prezentacji kartograficznej.
A shift from data through transformation leads to a specific graphic solution (compare Part I). In the article such solutions are referred to as cartographic presentation forms. In cartography, a logical and methodologically correct transformation from data to graphics results in presentation forms, which differ according to the type of data, transformation and visualization, i.e. the applied presentation method. The article discusses criteria and various classifications of cartographic presentation methods which appear in cartographic literature. Potential capabilities of cartographic presentation are the subject of cartographer's interest. In literature there are numerous considerations aiming to establish which method of presentation is appropriate for particular data, or what data can be presented using a particular presentation method. They attempt to link measurement levels, graphic symbols, visual variables and other attributes of presentation. Different combinations of those attributes result in various, more or less reasonable graphic solutions. After discussing more significant of these attempts, the author presents her own views on potentiality of cartographic presentation (fig. 5, 6, 7). From the scheme outlined in the first part of the article she derives particular graphic solutions, evaluates their correctness, estimates popularity and attaches names of specific presentation methods to them. She also attempts to label new solutions, which seem to be methodologically correct, but which have not been named yet. These considerations supplement Polish classification of cartographic presentation methods.

Opis:
Poprawne stosowanie kartograficznych metod prezentacji warunkuje czytelność redagowanej mapy. Wiąże się z tym m. in. wybór odpowiednich danych statystycznych. Często sprawia on autorom map wiele trudności, dlatego stał się powodem niniejszych rozważań. W artykule przedstawiono próbę klasyfikacji danych za względu na ich charakter. Zaprezentowano poglądy kartografów związane ze stosowaniem danych do dwóch metod prezentacji: kartogramu i kartodiagramu. W dalszej części artukułu przedstawiono analizę danych na mapach w atlasach geograficznych oraz badania ankietowe, których celem było skonfrontowanie przedstawionych poglądów z praktyką kartograficzną.
Proper application of cartographic methods of presentation is a condition for map's readability. It is related to a choice of appropriate statistical data. The article presents an attempt to classify data by type (fig. 1). Absolute data is represented by absolute numbers. They can be divided into two groups: proper - simple data represented by absolute numbers and transformed, which despite undergoing a transformation (e.g. averaged in time or related to the whole set) are still absolute numbers. Relative data is represented in fraction form, in relation to a particular component. Relative data can be proper, shown as a fraction, and transformed. Data type is of significance when differentiating between two types of cartographic presentation: choropleth map and diagran map. In cartographic literature a lot has been written about the selection of data for choropleth map presentation. The choropleth map method is usually recommended for presentation of ralative data. Data selection for diagram map presentation is much more disputable. Most handbooks recommend absolute data. Unfortunately this recommendation is not supported with any evidence. Some authors allow also relative data, but they do not provide any evidence either. Therefore there is no specific advice as to which type of data should be chosen for diagram map presentation. This research tried to establish the practical solution to the problem of data selection. One of the methods is an analysis of maps published in geographic atlases. 3656 diagram maps from atlases have been analyzed in order to determine the type of data used for them. The results showed absolute data to be the majority (86,4% of analyzed diagram maps). Diagram map presentation of relative data was applied significantly less often (4% of the total number of diagram maps). Another method of establishing a connection between theory and cartographic practice is a survey. Survey questionnaires were distributed twice to geography students at Warsaw University and Higher School of Pedagogics in Kielce. The first survey was to establish the methods of data selection by individuals who had not been acquainted with the rules of cartography. The second survey, conducted after a oneyear cartography course, was to determine the application of theory in practice. There were two types of tasks. The first one was to invent map titles (an open task). In the second part students were given several titles and asked to decide, which of them could be presented on a particular map (a closed task). Maps in the questionnaire had to be perceived similarly by all participants and should not be associated with any real terrain. Therefore fictional maps had been prepared. The first survey included 178 students (100 from Warsaw, 78 from Kielce). It showed that data selection for diagram maps and choropleth maps is not intuitive. The participants asked to suggest map topics handled diagram maps rather well; the results for choropleth maps were worse. Detailed analysis of chosen topics showed that the students had difficulties with both methods. The participants could not differentiate between the two types of maps and often assigned to them the same topics and therefore the same data. The second survey included 158 participants ( 84 from warsaw, 74 from Kielce). In both groups there was an increase of the number of correct answers (fig.11). However the results in both centers were significantly different. In Warsaw there were more correct answers, while in KIelce only a decrease in the number of incorrect answers was evident. The conducted survey showed that data selection for the methods of cartographic presentation is not an easy task. Theoretical instructions quoted in handbooks are not intuitively followed by map users. Choropleth map presentation is usually connected with the application of relative data. Diagram maps usually show absolute data. This rule is respected in practice, alt-hough there are common exceptions. Some of the students, before as well as after the course, had different opinions-in the first survey unconsciously, basing in intuition or coincidence, in the second survey often consciously, claiming that particular data simply fit the map in question. Despite cartographic education not all the students acquired the rules. Different results in Warsaw and Kielce may suggest that cartography lecturers put different stress on this issue. However in both centers there is a visible improvement after the course has been completed. It can be assumed, that the results are more evident where the theory has been stressed more. In both schools, after the course had been completed, there was only a small number of incorrect or illogical answers. This shows that the students acquired presented knowledge. However in cartography some rules are more and some less logical. Presenting forests in green and waters in blue is beyond question. It is logical and obvious. Data selection for the methods of presentation is not as logical, therefore it is not as widely accepted.

Opis:
Artykuł jest poświęcony efektywności prezentacji kartograficznej. Przytoczono poglądy kartografów dotyczące czytelności i sprawności mapy. Przypomniano zasady graficznego projektowania map. Podjęto próbę ich weryfikacji na przykładach małoskalowych map tematycznych. Każda prezentacja graficzna powinna być efektywna, ponieważ jej zadaniem jest uzupełnienie słowa pisanego, przyciągnięcie uwagi odbiorcy, uczytelnienie przekazu tekstowego, wyeksponowanie najważniejszych informacji. Tak ważna rola grafiki sprawia, że prezentacja graficzna (mapa, diagram, wykres) wymaga należytego przygotowania. Użytkownik musi mieć możliwość zrozumienia języka grafiki, aby poprawnie wnioskować o przedstawianych zjawiskach. Istnieją liczne przykłady dobrze i źle zredagowanych małoskalowych map tematycznych. Praktyka kartograficzna pokazuje, że zasady związane z graficznym projektowaniem prezentacji kartograficznych zbyt często nie są respektowane podczas opracowywania małoskalowych map tematycznych zamieszczanych m.in. w prasie i Internecie. Na efektywność prezentacji kartograficznej składają się wiedza i umiejętności redaktora mapy oraz możliwości percepcyjne odbiorcy i jego przygotowanie do czytania i interpretacji map. Mapa ułatwia zrozumienie tekstu, któremu towarzyszy, lepiej niż tekst pokazuje przestrzenne zróżnicowanie zjawisk, przemawia do zmysłów.

The discovery in the cartographic collections of the Faculty of Geography and Regional Studies at the University of Warsaw of an original map by Charles Dupin – the first choropleth map – provided an opportunity to conduct a closer methodological analysis of the map and to investigate the subsequent development of this presentation method during the first half of 19th century. From relatively early on, the accepted principle was for choropleth map presentations to use statistical data still imprecisely referred to as relative, as well as using a distribution series as a method of generalizing data.

W artykule przedstawiono niekonwencjonalne możliwości prezentacji kartograficznej - mapy anamorficzne. Szczegółowo omówiono kartodiagram anamorficzny Dorlinga - metodę dość powszechnie stosowaną w kartografii brytyjskiej, która nie doczekała się jeszcze szerszego opisu w polskiej literaturze kartograficznej. Po krótkim rysie historycznym omówiono założenia metody i sposoby konstrukcji takich kartodiagramów. Pokazano przykłady map opracowanych w programie MapViewer oraz przykłady zastosowania tej metody w Wielkiej Brytanii.
The world can be presented on maps in an unusual, unconventional way. The commonly known arrangement of continents or countries may be abandoned in order to expose changeability of a presented phenomenon. Such graphic presentations are referred to as anamorphic maps. Areas of presented units (e.g. countries) are proportional to statistical values, e.g. population, gross national product (fig. 2.). The article presents the assumptions and construction modes of one of anamorphic methods - Dorling cartogram. Examples of maps prepared in MapViewer and examples of application of this method in Great Britain are presented. Method of construction of Dorling cartogram is discussed on the example of maps published in A new social atlas of Britain [A1]. Fig. 6 presents two maps: traditional choropleth map showing the population density of Great Britain by electoral constituency in 1:10 000 000 (fig. 6A) and Dorling cartogram (fig. 6B). Constituencies are presented as circles with the area proportional to population. Location is preserved, but coastal line and borders are distorted. Preparation of such maps without a computer is almost impossible. Figures 8, 9 and 10 show Dorling cartograms of the population of Poland prepared in MapViewer 7 in 2002 and 2007. These maps are difficult to interpret, because readers are not used to seeing the world in unfamiliar shapes. Therefore when preparing them one should attempt to keep the shape and vicinity of particular units. It is advisable to help the users by showing ad-ministrative zones or by attaching a 'traditional' map. Skillful users of anamorphic maps can obtain new information from them.

W artykule zanalizowano i oceniono możliwości opracowania map z zastosowaniem wybranych form prezentacji kartograficznej w jednym z programów typu GIS - MapInfo Professional. Kolejno omówiono opracowane w programie mapy kropkowe, izoliniowe, sygnaturowe, chorochromatyczne oraz mapy zasięgów. Podjęto próbę zweryfikowania poprawności rozwiązań metodycznych zastosowanych w programie i opisanych w podręcznikach użytkownika programu MapInfo.
There is no doubt that the use of GIS type programs is widespread. Almost any computer literate person who wants to experiment with the possibilities of the program is able to make an attempt to create a map or another graphic presentation. In the previous issue of Polish Cartographical Review, choropleth and proportional symbol presentation possibilities of the MapInfo Professional 10.5 program were evaluated. This article discusses and evaluates the remaining methods of cartographic presentation: the dot method, the isoline method, the signature method, the qualitative background method and the ranges method from the point of view of their cartographical correctness. Attempts to create maps in MapInfo have shown that proposed solutions are not fully correct and adequate. Relatively low general evaluation of the program results from its numerous mistakes and missing sections of instructions which often hinder the process of proper map elaboration instead of facilitating it. Despite the fact that MapInfo Professional contains a lot of useful functions, it is not fully developed and sometimes can even mislead the program user. Nevertheless it seems to have considerable potential to become a useful tool in editing correct maps. In order to do it, however, it should comply with the rules of cartography. Although GIS-type programs are supposed to present cartographic data adequately, it should be remembered that in many instances their default automatic options are insufficient. Possibility of creating a software which would allow a non-professional user (with no cartographic skills) to make a correct map is an issue to be considered.

The authors of the article pay their attention to the lack of a generally accepted classification of the cartographic presentation methods. The classification, which was described in the Ratajski’s handbook (1989) in the mostly extensive way, is commonly used in the Polish literature. According to the authors, it would be appropriate to modify one of the types of symbols (quantitative ones) as an independent method of data presentation at the quantitative level, in addition to the method of diagram, choropleth, dot method and isoline one.

Opis:
The authors present a content analysis of the selected textbooks for teaching the natural science in the Polish primary school in the scope of cartography and topography. Two series of textbooks edited by the Nowa Era publishing house and approved by the Ministry of National Education are used by the authors. The main aim of this analysis is to determine whether the textbooks meet the requirements of the new core curriculum. The psychological aspects that may cause the difficulties in learning the natural science for the students of the IVth-VIth classes of primary school are also discussed. The contents of textbooks are absorbed by the students in varying degrees. It is important, therefore, to take into account the psychological aspects of students’ learning and to draw the attention to the difficulties that may arise in the process of teaching in the classes IV-VI. Among them there are, inter alia, the difficulties in using a map scale, some problems with imagining the actual distances and areas, a height above the sea level and the relative heights, as well as the issues related to the students’ abilities to read a drawing of contour lines. In the process of natural science education in the primary school, it is very important to develop the children’s abstract thinking, which causes the stimulation of their spatial imagination. The various types of teaching aids, which can be helpful for the both groups, as for the teachers, so for the students, are discussed in this article. These are the atlases, models, interactive teaching aids, books and educational games. The analysis introduced in this article allows for a critical evaluation of the textbooks for primary school from the point of view of their content complacencies on cartography and topography with the new core curriculum. Teaching the bases of cartography and topography from an early age is very important, but developing the ability to use a map requires the continuous exercises. Working with a map helps to develop not only the practical skills, but also the students’ attitudes having a positive impact on the development of such qualities as conscientiousness, accuracy and patience; it also has an invaluable impact on the students’ spatial imagination.

The purpose of this article is to report a study aimed at systematic assessment of the functionality of commercially available software for the automatic generation of area cartograms. The issue of the wide choice of algorithms developed over the years for generating various types of surfaces has also been raised. Cartograms (called also anamorphic maps) are constructed by changing the surface area of each spatial unit in step with the corresponding value of the mapped thematic variable (area cartogram) or changing accordingly the distance between the preselected focal point and other points on the map (distance cartogram). Depending on the shape of mapping units, the following three types of area cartograms can be distinguished: - proportional symbol cartograms were the original shapes of mapping units have been replaced with simple geometric shapes such as squares, rectangles or circles (for example, Dorling Circle Cartograms, square cartogram); - continuous regular cartograms where the shapes of areal units on the map resemble the actual shapes of the mapped units but their boundaries have been geometrized to consist of perpendicular sections; - continuous irregular cartograms where the shapes of areal units on the map resemble the actual shapes of the mapped units but unit boundaries are not straight lines. Cartograms can also be constructed to preserve spatial contiguity (continuous cartograms) or not (noncontinuous cartograms), with the latter often preserving the underlying neighborhood relationships to some degree. While constructing area cartogram, one needs to decide first the type of a surface to be developed, and therefore, the algorithm to be applied. The next step in map construction is the choice of software, where tool selection depends often on the predetermined type of the cartogram. The study surveyed five programs for the construction of area cartograms – all available free of charge. Each of those software tools was used to generate area cartograms portraying data from the 2010 presidential election in Poland. Two groups of area cartograms where generated for the purpose of this study: maps of the entire Poland by voivodships, showing the number of valid votes cast for the two presidential candidates in each voivodship, and maps of the Mazowieckie voivodship by county, portraying the number of valid votes cast for the individual candidates in each county. The subsequent in-depth assessment of surveyed programs took into account eleven criteria including the number of cartogram types that might be developed using each program, availability of tools for the proper legend construction and display, possibility of supplementing the cartogram with complementary choropleth maps, the option for inserting map labels, the type of spatial data that can be used in the software (reference to points, lines, polygons) and so on. The study has demonstrated that the tool included in the ArcGIS (Cartogram Utility for ArcGIS) best met the survey criteria scoring 9 points. The application Scape Toad placed second (7.5 pts.), while MapViewer 7 came third (6.25 pts.). When generating cartograms in the available GIS programs, one should also pay attention to the visual qualities of the generated maps, and in particular, to the resemblance of shapes of spatial units on the map to the their actual geographic boundaries. Since the shape outlines obtained on the map vary depending on the underlying geodetic reference system, the best coordinate system for the mapped area should be selected. However, if such system cannot be used within a given cartogram generating tool, then the obtained cartogram should be exported and refined with some general software package for graphic editing.

W artykule przeanalizowano i oceniono możliwości opracowania kartogramów i kartodiagramów w jednym z programów typu GIS -MapInfo Professional 10.5. Omówione możliwości programu skonfrontowano z zasadami metodyki kartograficznej.
Autors analyze and evaluate the possibilities of elaborating choropleth maps and diagrams using one of the most popular programs for servicing geographic information systems - MapInfo Professional 10.5. The article focuses only on two forms of cartographic presentation since they are the most frequently used and described in detail in MapInfo. The classification of map elaboration methods used in the MapInfo program is completely different from the classification accepted in Polish cartography. Not only is the "classification" completely different, but also MapInfo features methods unknown and incorrect from the cartographical point of view. These erratic solutions adversely affect the evaluation of the program. MapInfo Professional is made for a wide range of potential users, therefore it would seem natural to expect that they be given correct basics of cartographic methodology. Terminology used both in the program and in the MapInfo guides very often differs from the terminology accepted in Polish cartography, which is a serious problem. Not only does it adversely affect the understanding of the program, but also causes chaotic terminology to spread. In the analyzed program the diagram can be generated by as many as four methods of generating a thematic map which makes it the program's most developed method of cartographic presentation. However, it is impossible to generate a diagram map illustrating values of a phenomenon with the use of a graph. Considering all sorts of diagrams (one- and multi--parameter, flat and three-dimentional block), it appears that only a small part of those can be generated in MapInfo Professional. There are options to elaborate one parameter flat geometric diagrams in the shape of a circle, half circle, column, square, triangle and polygon. While editing, the user has the option of changing their filling and contour. The lack of the option to adapt the size of diagrams to the size of base units is the program's very serious disadvantage, as automation and acceleration of map elaboration process is a feature quite expected of GIS software. Including an adequate algorithm seems indispensible. It is possible to generate a line diagram in the same form as a related to point or an area diagram in the program. In such a case the diagram is put in the "middle" of the line to which it refers (fig. 8). The solution is completely inconsistent with cartographic methodology and cannot be classified within cartographic methods of presentation. According to the information in MapInfo user guide (2008) the so-called division method is the equivalent of the second method of presentation mentioned in this article- the choropleth map. It appears, however, that with this "method" it is possible to present all quantitative data. There is no warning that the choropleth map can only be applied for presenting relative data. Moreover, there is no option to generate a continuous or two-variable choropleth map, or a correct legend. Attempts to generate choropleth maps and diagrams in MapInfo have proved that the suggested solutions are not entirely correct and satisfactory. Although the program contains many useful functions, they are underdeveloped and occasionally can even mislead the user.

W artykule omówiono programy komputerowe, służące do automatycznego opracowywania kartograficznych anamorfoz powierzchniowych. Poruszono kwestię algorytmów, na podstawie których można opracować różne typy anamorfoz powierzchniowych. Celem artykułu była również ocena dostępnego na rynku oprogramowania, służącego do generowania takich anamorfoz. Opracowując kartograficzne anamorfozy powierzchniowe należy zadecydować, jaki typ mapy chcemy otrzymać, a tym samym jaki należy zastosować algorytm. Kolejnym etapem jest wybór oprogramowania, które często uzależnione jest od wcześniej wybranego typu anamorfozy. Przedstawione w artykule programy są bezpłatne. Do wykonania anamorfoz w analizowanych programach wykorzystane zostały dane dotyczące wyborów prezydenckich w Polsce w 2010 roku. Na potrzeby badania wykonane zostały anamorfozy powierzchniowe Polski w podziale na województwa oraz mapy województwa mazowieckiego w podziale na powiaty. Wybrane programy zostały poddane wnikliwiej ocenie. Wyniki badań pokazały, że programami, które w największym stopniu spełniają założone kryteria są: Cartogram Utility for ArcGIS, Scape Toad oraz MapViewer 7. Przy opracowywaniu anamorfoz powierzchniowych ważny jest kształt otrzymywanej mapy. W zależności od zastosowanego geodezyjnego układu odniesienia można otrzymać różne anamorfozy – bardziej lub mniej przypominające geograficzne zarysy jednostek administracyjnych. Dlatego też należy dobierać układ geodezyjny w zależności od obszaru, a jeżeli nie jest to możliwe, to po opracowaniu mapa powinna być dopracowana w programach graficznych.

Opis:
W artykule omówiono różne aspekty łączenia dwóch metod prezentacji - kartogramu i kartodiagramu na jednej mapie. Zwrócono uwagę na dopasowanie graficzne obu metod oraz na charakter i odniesienie przedstawianych w ten sposób danych. Pokazano przykłady takich połączeń, od najprostszych zastosowań po skomplikowane ujęcia anamorficzne.
Presentation of data on maps requires appropriate graphic methods to make the presented information logical and clear for map users. Depending on the range of information cartographers decide to use one, two or several presentation methods on a single map. A common combination is of a choropleth map with a diagram map. A choropleth map consists of area units (geometrical or administrative) designated with a color scale, a method for map background, while a diagram map consists of scaled diagrams appearing 'on top'. Because of this the two methods match and do not interfere graphically. Thus more data can be presented on a single map. It is important that data is logically selected and thematically linked, to create a new quality -communicate new information. Let us look at a combination of a choropleth map and a diagram map in relation to data selection. Considering possible combinations of two types of data (relative and absolute) with two methods of presentation, four types of combinations can be distinguished. (fig- 2). Type A is the most common and most correct according to cartographic methodology. Type B is also quite common. Type C seems incorrect because of a choropleth presentation of absolute data, which is contrary to theoretical recommendations of cartographic methodology. The last type is against the rules of cartographic methodology and is not used. When analyzing a combination of a choropleth map and a diagram map on a single map it is worth having a look not only at the character of data but also at what it relates to. In the case of a choropleth map data al-ways relates to area units. In diagrams data can relate to points, lines as well as area. Therefore the following types of graphic solutions can be determined (fig. 10). Type I is definitely the most common combination. Both methods relate to the same area units, which significantly facilitates map reading and interpretation. Many maps of Type II can be found in atlases, especially in maps thematically linked to population and industry, where data is related to points (diagrams) and area (choropleth). In such cases choropleth map is used to present various markers in relation to whole area unit: voivodship, countries, eta, while a diagram map presents e.g. cities or industrial centers. Type III is used when there is a need to show movement against the background of a choropleth map. Often the presented topic is so broad that it requires several graphic techniques simultaneously. They can be various types of diagrams (various shapes and colors), a complex choropleth map (two choropleth maps superimposed), various signatures and other methods of presentation (isolines, dots, ranges). Browsing through maps one can easily find ones with simultaneous use of several choropleth maps and diagram maps. There also exist some more complex combinations, which result in a single 'new' method of presentation, such as choropleth maps basing on a diagram or cartograms. Map authors combine the choropleth method with a diagram method to present a certain group of topics. This combination is often used to present socio-economic issues, because they require quantitative or ordering methods, of which a choropleth map and a diagram map are the most popular. While selecting data for cartographic presentation it should be remembered that using two or more sets of data on a single map has to be justified. Data shown on a single map has to be complimentary, self-explanatory and selected correctly from the point of cartographic methodology and graphic design. Any attempt to make an exhaustive and clear presentation of a particular problem on a map requires some graphic techniques involving a combination of cartographic methods. Clarity of such presentation depends on data selection, graphic design and perception of map user. Presented analysis does not conclude the topic of research, rather it opens the door towards a broader view of the potential of combining various cartographic methods.
