Polski Przegląd Kartograficzny

T. 30, nr 1

10-18

Autor artykułu, redaktor części kartograficznej elektronicznego 'Atlasu Polski' opublikowanego w 1997 r., po przypomnieniu wydanych dotychczas w Polsce atlasów elektronicznych, prezentuje koncepcję i kolejne etapy opracowania atlasu, jak również zawartość i sposób ujęcia poszczególnych elementów treści.

Atlas Polski, published in 1997 is the second (after Szkolny Atlas Polski) electronic atlas of this country. The cartographic part of this atlas consists of four elements: 1. General-reference map of Poland 2. Thematic maps 3. Thematic city maps 4. Statistical maps. The general-reference map serves as a basic map in this atlas. It consists of 8 thematic layers as well as the map legend. The map contains 5 levels of detail. It is digitized in vector format. The map was prepared using a computer program complied in Borland Delphi 1.0. A set of 27 thematic maps of both physical and socio-economic contents is the second element in this atlas. Each of these maps is available in two levels of detail. Maps are stored in raster format. The diversity of map themes is also reflected by the map design methods. The following methods were applied on these maps: isarythms, graduated symbols, nominal point and areal symbols as well as the dasymetric method. The atlas also contains a set of 7 city structure maps of the Poland's largest cities and metropolitan areas. These maps are also stored in raster format and are available in 2 levels of detail. They major content is composed of the presentation of transportation network and dominant land use forms. The atlas contains a set of 114 statistical maps in 11 thematic categories. Two mapping methods were used in this map group: choropleth and graduated symbol. The basic unit areas are the major administrative units. The electronic atlas elaboration process differs from the elaboration of a printed one. Apart from the strictly cartographic processes, the electronic atlas system also requires design of a map visualization system and a graphical user interface. Also, the very cartographic representations in an electronic atlas posses a number of properties differing from the features of a printed one. ¸
