DBTL — Provincial Technical Paper 1:10,000 grayscale (Section B7D2)

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（Topographic Database）生成的1:10000比例尺灰度省级技术图纸（Provincial Technical Paper，简称CTP），既支持以Web地图服务（WMS）的形式提供，也可通过单独的下载分幅获取。每幅1:10000比例尺的分幅覆盖8千米×5千米的区域，所有分幅均采用北向上的方位，图幅长边沿东西向排布。分幅按照当前区域制图标准进行裁切，因此保留原有标识符（例如C2d4）。由于分幅裁切基于高斯-博伊达制图坐标系（Gauss-Boaga cartographic system），因此通用横轴墨卡托-WGS84（UTM-WGS84）公里网格与该制图分幅可能无法对齐。
