Base map CR 1:25,000 - colour seamless - 09750705

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数据集采用源自捷克共和国基础地理数据核心库（Fundamental Base of Geographic Data of the Czech Republic, ZABAGED®）与捷克共和国地理名称数据库Geonames的数字技术完成生产。该数据集直接提取自IS SMD技术线路的制图数据库Data10。其栅格数据分辨率为800dpi，位深度为24比特。数据集以TIFF格式分发，采用LZW压缩算法。导出单元为边缘与S-JTSK基准轴平行的5×5千米地理区块，此类区块通过文本文件（TFW）实现地理配准，适配S-JTSK Krovak EN与WGS 84 / UTM 第33N带两种投影坐标系。
