Base map CR 1:25,000 - colour seamless - 10950470

Since 2002, the ZM 25 is produced using digital technology from the Fundamental Base of Geographic Data of the Czech Republic (ZABAGED®) and the database of geographic names of the Czech Republic Geonames. Data are derived directly from the cartographic database Data10 of technology line IS SMD. The resolution of rasters is 800 dpi and the color depth is 24 bit. The distribution is in TIFF format (LZW compression). The export units are 5x5 km segments with edges parallel to S-JTSK datum axes. Segments are georeferenced in the coordinate system using text files (TFW) for S-JTSK Krovak EN and WGS 84 / UTM zone 33N projections.自2002年起，ZM 25数据集采用源自捷克共和国基础地理数据基础库（ZABAGED®）以及捷克共和国Geonames地名数据库的数字技术进行生产。数据直接来源于技术线路IS SMD的制图数据库Data10。其栅格数据分辨率为800dpi，色深为24比特。数据以TIFF格式（采用LZW压缩）进行分发。输出单元为边平行于S-JTSK基准轴的5×5千米图幅。各图幅通过文本文件（TFW）实现地理配准，对应坐标系包含S-JTSK Krovak东北坐标系与WGS 84/UTM第33N带投影。
