Topographic Section 1:25,000 of the third military mapping - 5150-001

Colour raster copies of different archived issues, so called topographic sections (toposections) at scale 1:25,000 originate in the Third Austrian Military Mapping. The maps were published between 1872 and 1953 in Austro-Hungarian Empire and later in Czechoslovakia and other successor states. The territorial extent of the file significantly exceeds boundaries of today's Czech Republic.不同存档版次的彩色栅格副本，即比例尺1:25000的地形剖面图（toposections），其源头可追溯至奥地利第三次军事测绘。该批地图于1872年至1953年间在奥匈帝国境内出版，后续则在捷克斯洛伐克及其他继承国发行。本数据集涵盖的领土范围显著超出现今捷克共和国的国境边界。
