historical ponds, landuse, old maps, Chrudimka river

This study deals with the possibilities of creation of a map database of historical ponds and its usability in combination with other sources of spatial information, using an example of a compact territory. A number of available data sources were used for the creation of the database: the maps of the historical exploitation of the landscape (the military survey, the Stabile Cadastre), the digital database of water management data, the database of geographical data of the Czech Republic, etc. The methods of both automatic (GIS) and manual localisation of basins were tested for the territory in question. In addition, the paper describes in detail the method of creation of the digital layer in the GIS environment, pointing out the problems encountered in the creation of this layer of ponds from the II nd military survey (historical ponds). The paper also includes analyses of the areas of ponds from the II nd military survey (the altitude, the size) and analyses of the landuse of the areas of these ponds.
