Base map CR 1:25,000 - colour seamless - 11450675

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数据集便基于捷克共和国基础地理数据基础库（ZABAGED®）以及捷克共和国地理名称数据库Geonames的数字数据制作而成。其数据直接源自技术线路IS SMD的制图数据库Data10。栅格数据的分辨率为800 dpi，色彩深度为24位。数据以TIFF格式（采用LZW压缩算法）进行分发。导出单元为边长平行于S-JTSK基准轴的5×5千米幅块。各幅块均通过文本文件（TFW）完成地理配准，适配S-JTSK Krovak EN与WGS 84 / UTM zone 33N两种投影坐标系。
