Internet maps of cities are a digital counterpart of widespread maps in printed form. These maps contain quite differentiated information about cities, with extended presentation of subjects being of interest to tourists. They are regarded as one of the most popular group of maps. City maps are intended, first of all, for visitors (but also for inhabitants) as a medium of local information, mainly useful in planning of sightseeing and in looking for the location of different institutions, facilities for tourists and other services. In recent years, great development of Internet cartography is easily observed. It refers, first of all, to the quantitative growth. Many services (especially published by local governments) were supplemented with city maps. Not long ago each project was elaborated separately, but at present there are sets of maps in regional or thematic portals. Also series of maps should be mentioned, as the publications elaborated along uniform rules. There are professional providers of Internet maps as a komplement to traditional publishing houses. There are also important changes in the contents and form of Internet maps. Extended scope of the contents requires suitable extension of user tools of the digital maps. Besides simple solutions, such as bringing to Internet a digital copy of a printed map or elaboration based on the concept of a classic atlas (an ordered set of complementary representations of parts of a given area), the number of maps performing typical Geographic Information System tasks increases. A set of specific tools enables each user to prepare cartographic visualization according to his personal preferences. User functions allow to select components of the contents of cartographic representation, including its details and theme parameters, and the scope of visualized area. Efficient usage of maps is possible by means of tools binding cartographic representation with textual part (containing additional information and description of object properties) and other multimedia components. Some maps have complex functions for searching objects meeting selected conditions, including spatial criteria. There are procedures for determining distance and route optimization: finding the shortest way or the best traffic connection between desired points. Cartographic representation is often matched with photogrammetric elaborations. The present study describes main features and layout ideas of city maps with regard to their changes that took place during last five years (2000 . 2005). The comparison and conclusions are based on the analysis of a selected set of Internet maps, comprising 470 maps of Polish cities.
