Base map CR 1:25,000 - colour seamless - 11150450

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（Fundamental Base of Geographic Data of the Czech Republic，ZABAGED®）与捷克共和国地理名称数据库（Geonames）的数字技术进行生产。数据直接源自技术线路IS SMD的制图数据库Data10。其栅格分辨率为800 dpi，色彩深度为24位。数据集以TIFF格式（采用LZW压缩）进行分发。导出单元为边平行于S-JTSK基准轴的5×5公里图幅。针对S-JTSK Krovak EN与WGS 84 / UTM 第33N带投影，各图幅通过文本文件（TFW）完成坐标系地理配准。
