DBTL — Provincial Technical Paper 1:10,000 grayscale (Section C7A1)

Provincial Technical Paper scale 1:10000 grey scale produced by Topographic Database. The CTP is available both as a WMS service and as individual download sections. Each section on scale 1: 10,000 covers a territory of 8 km by 5 km. They are all oriented to the north, with the long side of the format in the East West direction. The sections are cut according to the current regional format and therefore maintain the current identifier (example C2d4). As the cut is set on the Gauss-Boaga cartographic system, it will happen that the UTM-WGS84 kilometre netting will not match with the cartographic cut.由地形数据库生成的1:10000比例尺灰度省级技术图纸（Provincial Technical Paper，以下简称CTP）。该数据集可通过网络地图服务（Web Map Service，WMS）获取，也可单独下载分幅文件。每份1:10000比例尺分幅覆盖8千米×5千米的制图区域。所有分幅均采用北向上方位，图幅长边沿东西方向延伸。分幅裁切遵循现行区域分幅规范，因此保留原有标识符（例如C2d4）。由于分幅裁切基于高斯-博埃加（Gauss-Boaga）制图坐标系，UTM-WGS84公里网格与制图分幅范围可能无法完全匹配。
