Base map CR 1:25,000 - colour seamless - 10700655

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数据集依托捷克共和国基础地理数据基础库（ZABAGED®）与捷克共和国地名数据库（Geonames）的数字化数据源进行生产。数据直接提取自技术线路IS SMD的制图数据库Data10。该数据集栅格分辨率为800 dpi，位深度为24位，以TIFF格式分发并采用LZW压缩算法。其输出分幅单元为边与S-JTSK基准轴平行的5×5千米图幅。各图幅通过文本文件（TFW）完成地理配准，对应坐标系涵盖S-JTSK克瓦克（Krovak）东向坐标系以及WGS 84 / UTM第33N带投影。
