Base map CR 1:25,000 - colour seamless - 11600545

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（ZABAGED®）与捷克共和国Geonames地名数据库的数字地理数据进行生产。其数据直接取自技术线路IS SMD的制图数据库Data10。该数据集的栅格（raster）数据分辨率为800像素每英寸（dpi），位深度为24位，分发格式为TIFF（采用LZW压缩算法）。导出单元为边平行于S-JTSK基准轴的5×5千米图幅，各图幅均通过文本文件（TFW）完成S-JTSK克瓦克EN投影与WGS 84/UTM第33N带投影坐标系下的地理配准。
