Aerial and Planimetric Tile Index

The tile index boundaries created at a scale of 1:1200. The dataset contains polygons used to partition the DC area into delivery units for aerial imagery, LiDAR, and planimetric mapping projects. Tiles are evenly divisible by the GSD.本数据集包含以1:1200比例尺生成的瓦片索引边界。该数据集包含用于将DC区域划分为航空影像、激光雷达（LiDAR）及平面制图项目交付单元的矢量多边形。所有瓦片均可被地面采样距离（Ground Sample Distance, GSD）整除。
