Base map CR 1:25,000 - colour seamless - 11100475

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®）与捷克共和国地名数据库（Geonames）的数字技术完成生产。其数据直接取自IS SMD技术线路的制图数据库Data10。该数据集的栅格分辨率为800dpi，色深为24位，以TIFF格式（采用LZW压缩）进行分发。输出分幅单元为边缘与S-JTSK基准轴平行的5×5千米图幅，所有图幅均通过针对S-JTSK Krovak EN投影与WGS 84/UTM 33N带投影的文本文件（TFW）完成坐标系地理配准。
