Generalization of settlements on Czechoslovak topographic maps

The cartographic generalization of settlements has always been a key issue in the technology of creating derived topographic maps. Czechoslovak topographic maps of 1:25 000 (1:25K), 1:50K, 1:100K and 1:200K scales were part of the most extensive unified topographic work of the Eastern Block, which covered the territory from Western Europe to Japan. This paper describes the methodology of survey and the results of generalizing the numbers and shapes of buildings on the derived topographic maps, which were created by experienced map editors in the latter part of the 20th Century. The results can serve as underlying statistical data for automated technology for creating derived maps from a 1:25K scale base topographic map.
