Opis:
W artykule omówiono pojęcie zabudowy z punktu widzenia prac topograficznych. Następnie pokazano sposoby przedstawienia zabudowy na mapach topograficznych w skalach od 1:5 000 do 1:200 000, a także problemy z tym związane. Artykuł zamyka analiza prezentacji zabudowy na nowej mapie 1: 50 000 wydanej przez Głównego Geodetę kraju.
Topographic maps in Poland are currently published by two independent goverment agencies : Head Office of Geodesy and Cartography (Główny Urząd Geodezji i Kartografii) and Military Geography Authority of the General Staff of the Polish Army (Zarząd Geografii Wojkowej Sztabu Generalnego Wojska Polskiego). The oveview of these maps is presented in the Table 1. On 1:10,000-scale each building is presented with a separate cartographic sign. Almost all buildings are shown (escluding the smallest ones located in the close proximity to other ones). Also, building located within the allotments are generally omitted. Buildings classed in the same category ((esp. row and semi-detached houses) are shown with a single sign, which causes certain misrepresentations. On 1:25,000-scale maps the majority of buildings is shown, however the smallest ones located in large distances from streets can be omitted. The presentation of built-up areas is composed of two separate elements: separate symbols for each building as well as the range of the entire built-up area (shown in color). The editors' guidelines for 1:50,000-scale maps were similar to those for 1:25,000-scale. As far as the maps the scale of 1:100,000, the difference lies in the presentation of built-up areas, which are shown in black. Consequently, the symbol for single buildings is the same as the one used to present the whole built-up area. On 1:200,000-scale maps the symbol used to show separate farm building was eliminated. Cartographic generalization (mostly quantitative) as well as the correct classification of buildings (either to densely or sparsely populated area) are considered to be the most vital problems concerning the presentation of settlement. A new method of settlement presentation was introduced on the new series of civilian 1:50,000-scale topographic maps published by the Surveyor General of Poland (Główny Geodeta Kraju) since the mid-1990s. Maps published before that date presented settlement classification based on the density and size of buildings. However, there was no functional classification applied. Functional categories have been first used on these new map series, which can be considered as a revolutionary change. The following classes were introduced: compact multifamily dwellings, dense multifamily dwellings, dense single-famly dwellings as well as industrial zones. The remaining buildings are presented with sings for each separate building. The settlement is shown in brown, which makes it possible to overprint geographic names in black. However, the presentation of built-up areas by showing the range of buildings instead of presenting the range of the whole area can be considered questionable, as it weakens its graphic presentation.The idea of presenting dense multifamily dwellings with a separate sign also seems doubtful. On the other hand the lack of a symbol for high-rise buildings is a serious drawback of the map. The presentation of separate buildings is very subtle, yet legible. The elimination of a separate symbol for farms is an important modification to the map content. To sum up, owing to the new graphic techniques and new theoretical approach the map presents settlement in a much better way compared to the previous ones.

Po określeniu pojęcia dziedzictwa przyrodniczo-kulturowego i przedstawieniu problemu redakcji mapy na podkładzie nowej Mapy topograficznej Polski 1:50 000, omówiono koncepcję treści Mapy dziedzictwa przyrodniczo-kulturowego Polski 1:50 000. Szczegółowo scharakteryzowano poszczególne wyróżnienia dziedzictwa przyrodniczego i dziedzictwa kulturowego oraz wskazano możliwości wykorzystania mapy.
The authors describe a concept of contents of a Map of the natural-cultural heritage of Poland 1:50 000. First they define the notion of natural-cultural heritage, and then characterize particular distinctions of natiral heritage and those of cultural heritage. They also indicate possible uses for such a map. The contents of Map of the heritage comprises the objects of heritage, i.e. the most valuable elements of geographic environment. In the case of natural elements of environment we can talk of "natural heritage ", that is the object and areas of exceptional aesthetic value, examples of ecological and biologic processes, as well as traces of important events in the Earth's history. In the case of objects and phenomena resulting from material and immaterial human activities, we can talk of "cultural heritage". Map of the heritage is drawn on a bases of a new Topographic map of Poland 1:50 000, with which the overprinted graphic symbols have to agree. It was assumed that the map should be accessible to general, nonspecialist public, therefore the legend distinctions should be comprehensible for any reader with at least secondary education. Map's contents is divided into two groups. The first group, "Natural heritage (fig.1) contains three topic categories: - environment protection - didactic stands - degradation of the natural environment The second group, "Cultural heritage (fig. 3) is divided as follows: - major archeological sites - historic sites - major events and non-existent objects Map of the heritage also includes elements of tourist infrastructure (fig. 2). Additionally, a hypsometric sketch has been included, with physico-geographical regionalization of the presented area (fig. 5). The map could be used in many fields, especially regional planning, education, tourism and promotion of "little homelands". Rich contents and the scale of presentation mean that the reader would gain access to previously unavailable information.

Opis:
Potencjalne strefy zalewowe mogą być wyznaczane z wykorzystaniem numerycznego modelu terenu opracowanego na podstawie map topograficznych i uzasadnionego przekrojami poprzecznymi pomierzonymi bezpośrednio w terenie. Właściwa interpretacja rzeźby z mapy topograficznej jest - szczególnie w opracowaniach lokalnych - najefektywniejszym sposobem przewidywania zakresu potencjalnych powodzi.
The Digital Terrain Model DTM-based potential backwater zone map pilot project ordered by the World Bank resulted in the preparation of maps of the town of Kłodzko, the communes of Kamieniec Ząbkowicki and Brzesko and the city of Kraków - the area influenced by the Vistula river. Terrain survey is the most detailed (and also the most expensive) method of obtaining DTM data. It is used whenever very high accuracy of the terrain representation is necessary. However, for most purpose the already existing data in the form of either the PHARE Project aerial imagery or satellite imagery (such as IKONOS) can successfully supplement the original survey. Thanks to the digital aerotriangulation it is possible to prepare DTMs at the scales of 1:10,000 and 1:25,000 using those sources. The other method, much less common in Poland, consists in the use of the fly-spot scanning technique. If it is impossible (or too expensive) to use either of the above descrobed methods, the best possible source are topographic maps. In our project the 1:10,000-scale topographic maps were used. A Digital Terrain Model based on 1:10,000-scale topographic maps is considered to be the adequate source to prepare a backwater zone map at the same scale providing that the following conditions are wet: the height of escarpments, embankments and other topographic elements are correctly represented; the elevation of skeleton lines (which are not represented on a map) is not distored, the surveyed cross-sections are used to construct a model of the river bed and valey; additional sources (such as base maps) are used to represent settlements and eventually, the final result has to be verified. The flood zone line is the line of intersection between a Digital Terrain Model and a Digital Water Surface Model. Thanks to the possibility of generating the depth contours at desired intervals there are numerous possibilities of performing analyses of risks and flood damages and especially the application of these isobaths to map the limit between the zones of medium and high flood risk.

Opis:
W artykule porównano zakres treści i formę graficzną trzech polskich cywilnych map topograficznych w skali 1:50 000: w układzie "1965", w układzie "1992" oraz w układzie "WGS-84".
In Poland currently there are three topographic maps at the scale of 1:50 000 for civil use: -map in ,,1965" coordinate system published in 1977-1982 by the Head Office of Geodesy and Cartography, covering the whole country, - map in ,,1992" coordinate system, exept first 48 sheets of Mazowsze region, which were edited in ,,1942" coordinate system), published in 1995-2002 by the Surveyor General of Poland, covering almost 60% of the country's area, - ,,WGS-84" map in UTM projection published in 2003-2006 by the Surveyor General of Poland with the Polish Military Gegraphic Service, covering 25% of the country's area. Comparison of the range of contents and graphic form of the three maps clearly shows the superiority of the map in ,,1992" system. Compared to the other two it employs a new way of presenting built-up areas. It contains significantly more information about the function and intensity of exploitation of built-up areas and offers provides a more complete picture of anthropogenic landscape than any other map in that scale, in Poland or abroad. In addition, the ,,1992" map has the most detailed presentation of streets and relief. Detailed depiction of plant cover and crop areas is achieved by lowering the area limits, below which a particular object is not shown with its outline. Similarly, lowering of the length limit of watercourses and area limit of water pools led to a more detailed presentation of water network. The contents of the ,,1992" map was also enriched by a much larger number of acronyms and descriptions of public buildings and industrial sites. The map in ,,1965" system was printed in four colors, ,,WGS-84" map in five, and the ,,1992" map - in six. The comparison of graphic form of the three maps gave lowest marks to the least readable "1965" map. The ,,1992" map is characterized by wider use of color, which adds to its readability and attractiveness. Substituting black color, traditionally used for buildings and road network with brown resulted in higher graphic capacity and better presentation of public buildings and industrial sites. Consistent use of green for green areas, blue for water and light brown for relief facilitates perception of particular categories of map contents. Application of color patterns for grass areas and orchards allowed for a clear and detailed presentation of their outline. The graphic level of the .WGS-84" map is higher than that of former military maps and the map in "1965" system, partly due to the application of several solutions from the ,,1992" map (e.g. consistent use of green for green areas, simplified presentation of built--up areas). Some elements of the ,,WSG-84" map, such as main roads or borders of natural reserves, are more readable than in the other two. The comparison of the three maps in 1:50 000 shows that the newly planned map in this scale, which is to be prepared using the topographic database should base on the map in ,,1992" coordinate system.

Opis:
W artykule omówiono etapy opracowania koncepcji mapy topograficznej 1:50 000 wydanej w latach 1995-2002 przez GUGiK, a także podstawowe założenia tej koncepcji. Przy omówieniu treści i formy graficznej mapy zwrócono szczególną uwagę na nowy sposób ujęcia zabudowy.
The first Polish topographic map in civilian version at the scale of 1:50 000 was prepared in "1965 system" by re-arranging and re-editing of the sheets of military 1:50 000 map in "1942 system". It was published in the years 1977-1982. In 1993 as a result of an order from the Surveyor General of Poland, preparation of a completely new concept of a topographic map in 1:50 000 was started. The first, initial instruction to this map was issued in 1995; its final version, which included the experience gathered during the editing of the first several dozen sheets appeared in 1998. The 1:50 000 map in its contents and graphic form refers to a map in 1:10 000, the preparation of which started in 1994. The new concept of a 1:50 000 map accounted for its multi-purpose character. An analysis of a range of contents and graphic forms in topographic maps of Western countries was conducted; the new concept also referred to Polish graphic tradition between the World Wars. Between 1995, when the publication started, and 2002, 589 sheets were published, which cover 60% of Poland's area. The forst 48 sheets of the Mazowsze region were edited in "1942 system", which bases on Krasowski elipsoid; all the following sheets were edited in "1992 system", basing on a GRS-80 ellipsoid.The map is printed on standard sheets of 580x470 mm. Every sheet includes the explanation of all the symbols and most abbreviations with Polish and English explications. On the new map the number of applied signs has been significantly reduced (in comparison to the previous map). At the same time its contents has been extended to include new, important elements, e.g. industrial and store areas, but stations, marked tourist routes, border checkpoints, bethymetry of lakes, border zones. However the biggest changes regarded methods of presentation of buildings. To show their variety a functional criterion has been applied. Industrial and governmental buildings have been differentiated from other buildings and built-up areas. Dwellings (including farm dwellings) have been differentiated according to their density and buildings' size. Compact multifamily dwellings, dense multifamily dwellings, dense single family dwellings have been shown as three different types of built-up area, while disperse dwellings have been marked with separate symbols for particular buildings or farms. The 1:50 000 map was printed in unified six color version (black, dark brown, blue, green, red, light brown). Application of dark brown to dwellings and roads was particularly important for the graphic picture, because it relieved the map and increased its graphic capacity, e.g. it made it possible to clearly mark government and industrial buildings. Consistent use of green for agriculture and vegetation and light brown for surface relief also improved the graphic quality of the map. In comparison to the previous map, the new 1:50 000 map has more precise drawing, which has been achieved with wider use of colors and patterns as well as the reduction of the size of symbols, their simplification, and reduction of line width. The map was met with positive reactions of its reviewers and users; its authors also got. The Awars of the Minister of Internal Affairs and Administration. After the reorganization of the Head Office of Geodesy and Cartography in the beginning of 2002, the publishing of further sheets was abandoned; it was decided, that the remaining area would be covered with a military map prepared in V Map Level 2 technology complying with NATO standards, and adapted for civilian use.

W pierwszej części artykułu omówiono znaczenie generalizacji w procesie budowy Krajowego Systemu Informacji Geograficznej oraz teoretyczne zasady generalizacji sieci dróg i zabudowy dla skali 1:50 000. W drugiej części opisano narzędzia informatyczne do automatyzacji procesu generalizacji oraz implementacje bazy wiedzy dotyczącej reguł generalizacji w środowisku programowym DynaGEN. Poprawność opracowanej bazy wiedzy zweryfikowano przez przeprowadzenie dwóch eksperymentów. Pierwszy eksperyment dotyczył generalizacji warstw tematycznych Bazy Danych Topograficznych (BDT) sieci transportowej i zabudowy w obrębie podwar-szawskiej miejscowości Łomianki. Drugi eksperyment polegał na generalizacji warstwy tematycznej sieci transportowej w okolicach Kowalewa Pomorskiego.
The most advanced software for generalization of digital data available on the market today is that by Laser Scan. The company participated in the AGENT The most advanced software project, which was described in the first part of the article. What resulted from the project was Clarity, a very advanced map generalization system. What differentiated Laser Scan from then contemporary software, was the fact that it accounted for the contextuality of generalization, i.e. the same objects can be generalized differently depending on the objects surrounding them. It was possible because of application of a unique object technology, where each object could be generalized in many ways depending on the context. The DynaGEN system by Intergraph is an alternative generalization software. It is less expensive and has significantly more practical applications. It uses the same generalization algorithms, but cannot do alternative operations. Therefore one can either generalize small areas in an interactive way, or generalize automatically with later manual corrections. Similarly to Laser Scan, it requires software configuration and also the construction of knowledge base. The second part of the article presents an implementation of the knowledge base containing the rules of generalization in DynaGEN environment. The accuracy of the arranged knowledge base had been verified by two experiments. The first one involved generalization of thematic levels of Topographic Database of the road network and buildings within the town of Łomianki near Warsaw. The second one consisted in generalization of the road network in the area of Kowalewo Pomorskie in Northern Poland. The knowledge base prepared in DynaGEN system contained two sets of rules. The first one included the rules applied automatically and which, in limited sequence, are used for the initial preparation of data. The second set contained the rules describing basic types of interactive generalization processes supervised by a cartographer, which were vital for the application sequence. The generalization of a road network consists of two stages. The first one involves an analysis and initial data processing. Its range includes a construction of a hierarchical model of a road network and the connection of road segments within the whole area. The second, main stage of the generalization of a road network involves selection and simplification of paved roads, dirt roads and paths. Generalization of built-up areas is performed in one step, without initial data processing. The prepared knowledge data describes the process of generalization of topographic data from 1:10000 into 1:50 000. It provides universal material which can be implemented in various software environments.

Opis:
Artykuł jest próbą wskazania różnic i podobieństw między mapami topograficznymi w skali 1:25 000 różnych krajów Europy. Analizie poddano mapy: belgijską, czeską, francuską, hiszpańską, holenderską, niemiecką, szwajcarską oraz włoską. Porównanie osnowy matematycznej, sposobów przedstawiania rzeźby terenu, prezentacji sieci wodnej, osadniczej i komunikacyjnej oraz pokrycia terenu uwidoczniło znaczne różnice między koncepcjami wydawanych współcześnie map topograficznych. Głównymi przyczynami zróżnicowania map wydają się być odmienne cechy środowiska geograficznego oraz różnice tradycji kartograficznych poszczególnych krajów.
The first civilian topographic map in 1:25 000 published in Poland after WW II became, despite its short-comings, a basis for numerous thematic maps. It was reedited and used until the end of 1980-ies. Currently civilian topographic maps are available only in 1:10 000 and 1:50 000 (maps in '1992' coordinate system). Lack of a contemporary map in 1:25 000 makes it impossible to create thematic presentations comparable to the ones of the past, and makes it difficult to conduct field research. A new map in 1:25 000 should relate in its concept to the topographic maps in 1:10 000 and 1:50 000 mentioned above, and at the same time continue the best traditions of Polish cartography. It should also present a level similar to that of other European publications of the type. The article analyzes topographic maps in 1:25 000 currently published in Belgium, the Czech Republic, France, Spain, the Netherlands, Germany, Switzerland and Italy. The comparison shows that there are significant differences between them, visible even at the stage of analysis of their mathematical base. Various ellipsoids, systems of reference and cartographic projections are used, while altitudes are related to various sea levels. Maps also have different density of topographic grid and various ways of describing it. On all maps land relief is presented with contour lines, but with various contour intervals. Only some of the maps used hill shading. Also land cover differs (number of categories). Three approaches to the presentation of settlements can be distinguished. The first one is presentation of single buildings, the second - presentation of built-up areas, with the third being a combination of the first two. Significant differences appear in the presentation of functions of buildings and built-up areas (color, signatures, notes, lettering). Differences between maps are also visible in the presentation of surface waters and transportation infrastructure (roads, rail-roads). These result from different classification criteria. Graphic differences between analyzed maps are also well visible in the form of a variety of signatures and different color scales of print. The reason for such significant differences between European topographic maps in the scale of 1:25 000 results not only from different types of geographic environment, but mostly from different cartographic traditions of particular countries. Lack of common European standards of topographic map edition will probably make the concept of the future Polish map in 1:25 000 resemble the concepts of the topographic maps in 1:10 000 and 1:50 000 currently available in Poland.

Opis:
W pierwszej części artykułu opisano i zilustrowano reguły generalizacji sieci drogowej i zabudowy przy opracowywaniu mapy topograficznej 1:50 000 na podstawie mapy 1: 10 000. W drugiej części artykułu zostanie zaprezentowana implementacja bazy wiedzy na podstawie zdefiniowanych reguł w środowisku programowym Dynagen oraz przykłady praktycznego wykorzystania tej implementacji do generalizacji Bazy Danych Topograficznych.
Due to the development of geographic information systems, in the developed countries more than 70% of decisions in public administrations are taken basing on spatial data. Particular regions have their own databases with various levels of detail, usually corresponding to standard topographic scales (1:10 000, 1:25 000, 1:50 000 etc.). The question is whether it would be possible to keep just one, detailed topographic database and generate cartographic presentations in different scales from it, using automatic generalization of spatial data. This problem is particularly vital in Poland, because the National Geographic Information System (KSIG), which is being implemented at the moment, consists of, among other units, a Topographic Database (BDT) with the level of detail corresponding to the map in 1:10 000 and a Level 2 Vector Map (VMAP 2) with the level of detail corresponding to the scale of 1:50 000. Since 2002 the Faculty of Environmental Engineering and Geodesy of Agricultural University of Wroclaw together with the Warsaw University Chair of Cartography have been working on a research project "Automatization of the process of generalization of topographic maps from the scale of 1:10 000 into 1:50 000". In the first stage of the research attempts were made to elaborate a system of automatic genera-lization of road network and buildings with the use of DynaGen software. In the first part of the article the rules of generalization of these two components are presented and illustrated. Criteria and rules for the choice of streets and lower road categories are established (criteria of density, length, functionality and spatial relations). Generalization of buildings presented in the scale of 1:10 000 can be conducted in two ways: either with symbols of separate buildings or by replacing them with a symbol of a built-up area. In the first case we are dealing with the following types of generalizations: generalization of qualitative features, substitution of a collective symbol for separate symbols, choice of buildings, replacement of building outlines with symbols, building simplification, combining and changing of building location. In the second case separate objects (buildings) are replaced with a collective symbol (built-up area), the shape of which is further simplified, extended and combined.
