Base map CR 1:25,000 - colour seamless - 09900785

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地理数据基础库（Fundamental Base of Geographic Data of the Czech Republic，ZABAGED®）与捷克共和国Geonames地理名称数据库的数字技术完成生产。其数据直接提取自IS SMD技术线路的制图数据库Data10。该数据集的栅格数据分辨率为800dpi，色深为24位，以采用LZW压缩的TIFF格式进行分发。导出单元为边缘与S-JTSK基准轴平行的5×5千米分幅区块，各分幅区块通过文本文件（TFW）分别针对S-JTSK Krovak EN投影与WGS 84 / UTM第33北带投影完成坐标系地理配准。
