资源简介:

Bridges and Tunnel Entrances. The dataset contains polygons representing planimetric Roads, created as part of the DC Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO). These features were originally captured in 1999 and updated in 2005, 2008, 2010, and 2013. The following planimetric layers were updated: - Building Polygons (BldgPly) - Bridge and Tunnel Polygons (BrgTunPly) - Grate (GratePly) - Horizontal and Vertical Control Points (GeoControlPt) - Obscured Area Polygons (ObsAreaPly) - Railroad Lines (RailRdLn) - Road, Parking, and Driveway Polygons (RoadPly) - Sidewalk Polygons (SidewalkPly) - Stairs (StairPly) - Swimming Pools (SwmPoolPly) - Wooded Areas (WoodPly) METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.

《桥梁与隧道入口》。本数据集包含表征平面道路的多边形要素,其作为华盛顿特区地理信息系统(DC Geographic Information System, DC GIS)的组成部分,由华盛顿特区首席技术官办公室(Office of the Chief Technology Officer, OCTO)开发。该类要素最初于1999年完成采集,并分别于2005年、2008年、2010年及2013年进行更新。本次更新涉及以下平面图层: - 建筑多边形要素(Building Polygons, BldgPly) - 桥梁与隧道多边形要素(Bridge and Tunnel Polygons, BrgTunPly) - 格栅多边形要素(Grate, GratePly) - 水平与垂直控制点(Horizontal and Vertical Control Points, GeoControlPt) - 遮蔽区域多边形要素(Obscured Area Polygons, ObsAreaPly) - 铁路线路要素(Railroad Lines, RailRdLn) - 道路、停车场与车道多边形要素(Road, Parking, and Driveway Polygons, RoadPly) - 人行道多边形要素(Sidewalk Polygons, SidewalkPly) - 楼梯多边形要素(Stairs, StairPly) - 游泳池多边形要素(Swimming Pools, SwmPoolPly) - 林区多边形要素(Wooded Areas, WoodPly) 元数据内容尚处于验证阶段,可能会发生变更。
