Base map CR 1:25,000 - colour seamless - 11800500

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核心库（ZABAGED®，全称为Fundamental Base of Geographic Data of the Czech Republic）及捷克共和国Geonames地理名称数据库的数字技术完成生产。数据直接源自IS SMD技术线路的Data10制图数据库。该数据集栅格分辨率为800dpi，色彩深度为24位。数据分发格式为TIFF（采用LZW压缩）。导出单元为边长平行于S-JTSK基准轴的5×5千米分幅区块。所有分幅区块针对S-JTSK克腊索夫东北向（S-JTSK Krovak EN）与WGS 84 / UTM第33N带两种投影坐标系，通过文本文件（TFW）实现地理配准。
