Opis:: Various aspects of merging the chosen presentation methods (choropleth and diagram) on one map are discussed in the article. Attention is focused on the graphic match of both methods, on the character and reference of data presented in this manner. Examples of such matches are shown, from the simplest application to complicated anamorphic presentations.

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:: The online Atlas kartograficznych metod prezentacji [Atlas of cartographic presentation methods, hereinafter the Atlas] is a research project being carried out at the Department of Cartography of the University of Warsaw. The aim of the project is to systematize knowledge about the use of cartographic presentation methods. This study discusses selected issues related to two of the five presentation methods analysed in the project, viz. the choropleth map and the diagram map. A rational application of two quite commonly-used presentation methods leads to a number of problems. These problems are most easily visible during attempts to program its implementation in the web-based Atlas and are largely due to the difficulties with drawing a clear boundary between what is a good and a bad map. For this reason, the system operator’s skill and eye for the graphics of semi-automated visualisation seem to be of key importance.

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.

Opis:: W artykule przedstawiono różne możliwości opracowania kartodiagramów w wybranych czterech programach komputerowych typu GIS. Omówiono mapy opracowane w sposób automatyczny, według ustawień domyślnych oraz takie, których opracowanie wspomagane jest wiedzą kartograficzną wykonawcy. Prześledzono poszczególne etapy opracowania kartodiagramu oraz możliwości programów GIS w tym zakresie. Otrzymane mapy oraz ich legendy oceniono pod względem respektowania podstawowych zasad metodyki kartograficznej.
Two types of computer software can be used for map preparation: a graphic program, eg. Corel Draw orAdobe lllustrator, or Geographic Information System (GIS). The article presents various options of diagram map preparation in four selected GIS-type computer pro-grams: Maplnfo Professional 7.8, ArcMap 9.1 (from ArcGIS 9.1 package), MapViewer 7, Microsoft Map-Point 2006. The analysis involved using the programs to present statistical data in the form of a diagram map, and evaluation of the resulting map. Subsequent stages of diagram map preparation were analyzed as were the capabilities of particular programs in that respect (fig.1). The elements which are vital for map's correctness were analyzed in the first place. After defining the basie assumptions of the diagram map method and identifying errors possible at each stage it was possible to evaluate the accuracy of solutions applied in particular programs. Maps prepared using the default settings were analyzed as well as those, the preparation of which asked for some cartographic skill of the user. The analysis showed that the programs provided a similar level of options in respect to diagram map preparation. None of them is faultless, but they all have their strengths. Only MapPoint falls behind; it is significantly poorer and provides less options. It can be stated that Maplnfo, ArcMap and MapViewer are all similarly useful for diagram map preparation, although they differ in their functionalities at different stages of editing. Preparation of a proper diagram map asks for relevant cartographic skill. For a skilled user GIS programs can provide a tool for quick and simple preparation of acceptable and often visually attractive diagram maps. Programs are easy to use, so even an inexperienced user will be able to prepare a map with them. Unfortunately in such cases quality may suffer, because the programs contain some shorteomings and cartographically questionable solutions. There are also many 'traps' which await an inexperienced editor. Regretfully the programs do not include any limits as to the number of elements of the presented structure. Cartographic conventions and code of practice, which result from many years of experience should be considered during the preparation of GIS-type cartographic software. Such programs would enable any, even inexperienced, user to visualize data in a way both comprehensible and correct.

The free and all accessible Atlas of cartographic methods has been available on the Internet at www. educarto.pl since May 2012. The atlas was elaborated by the staff of the Department of Cartography of Warsaw University in 2010-2012. Growth of computer technologies has made it possible for everyone to author a map - especially a statistical one. Thus has appeared the need to prepare and make accessible to wider public a more elaborate guide than just a handbook or a set of instructions on how to run the program. The Atlas has been made to cater to the needs of those interested in learning basic rules of statistical map editing, so - of geography students, experts in spatial economy and environmental protection, surveyors. It is educational in character and aimed at showing quantitative methods and forms of cartographic presentation and focusing attention on map interpretation. It presents five quantitative forms and methods of presentation: diagram map, choropleth map, isoline map, dot map and quantitative symbols. The Atlas of cartographic methods is composed of two main parts (Fig. 1). The first part contains three 'chapters' of texts while the second - maps along with short commentaries. The first chapter is an elaboration entitled 'From the history of presentation forms and methods' and is illustrated with old maps. The second one - 'From data to map' - describes the process of editing a statistical map. It deals with data features and the possibilities of their transformation to fulfill the requirements of a specific presentation: - method of data reference (to points, area or line), data character (absolute, relative), method of showing data (continuous, discrete). The third chapter is entitled 'Methods step by step'. Its aim is to acquaint users with basic characteristics of the five forms of cartographic presentation. The second part of the atlas - 'Maps' - is a dynamic internet application and interactive environment for generating atlas full scale drawings. The application was programmed in PHP and is linked to MySQL database. The application's interface design was aimed to support the demonstrativeness of the Atlas - available functions have been limited to a minimum. The GUS (Central Statistical Office) Bank of Local Data resources (www.stat.gov.pl) served as material for elaborating maps in the Atlas. For elaborating a part of the Atlas full scale drawings an earlier prepared group of raster images was used. They were put on the server and shown in accordance with the parameters selected by the user. The remaining full scale drawings were created in a more complex way. Here applications programmed in PHP play an essential part. They process spatial and attribute data and display an automatically created map together with legend. The internet Atlas of cartographic methods can be treated as the first stage of a wider elaboration including all basic forms and methods of presentation.
