Base map CR 1:50,000 - colour seamless - 07001100

Since 2002, the ZM 50 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. The data are derived directly from Data50 cartographic database of IS SMD technology line. These files are by the application server service rasterized with resolution of 800 dpi, 24 bit colours and unified raster palette. The distribution is in TIFF format (LZW compression). The export units are 10x10 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 50数据集依托捷克共和国基础地理数据基础库（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。 该数据直接源自IS SMD技术体系下的Data50制图数据库。 应用服务器服务对上述文件进行栅格化处理，栅格分辨率为800dpi，色彩位深为24位，并采用统一的栅格调色板。 数据分发格式为TIFF（采用LZW压缩算法）。 数据导出单元为边界与S-JTSK基准坐标轴平行的10×10千米图幅。 上述图幅通过文本文件（TFW）针对S-JTSK Krovak EN与WGS 84 / UTM 33N投影坐标系完成地理配准。
