Base map CR 1:25,000 - colour seamless - 11300520

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库（Fundamental Base of Geographic Data of the Czech Republic, ZABAGED®）及捷克共和国地理名称数据库（Geonames）的数字技术完成生产。数据直接取自IS SMD技术线路的制图数据库Data10。该数据集栅格分辨率为800 dpi，色深为24位，以TIFF格式（LZW压缩）进行分发。其分发单元为边与S-JTSK大地基准轴平行的5×5千米图幅，各图幅基于S-JTSK Krovak EN与WGS 84/UTM 33N带投影坐标系，通过文本文件（TFW）完成地理配准。
