Base map CR 1:25,000 - colour seamless - 11800545

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地理基础数据基准库（Fundamental Base of Geographic Data of the Czech Republic，ZABAGED®）以及捷克共和国地理名称数据库（Geonames）的数字数据进行生产。数据直接取自技术线路IS SMD的制图数据库Data10。其栅格分辨率为800像素每英寸（dpi），位深为24位。数据以TIFF格式分发，采用LZW压缩算法。输出单元为边与S-JTSK基准轴平行的5×5千米图幅。图幅通过文本文件（TFW）实现地理配准，配准时采用S-JTSK Krovak EN坐标系与WGS 84/UTM第33北带投影。
