GRSM_LIDAR TILES_2016_2017

In 2016, counties in east Tennessee were flown to derive a lidar point cloud of ground elevations at approximately 8 points per square meter. In 2017, counties in west North Carolina were flown to derive a lidar point cloud of ground elevations at approximately 8 points per square meter. The lidar tiles represented in this feature service can be used to locate the most recent lidar data collection efforts in Great Smoky Mountains National Park. The corresponding Integration of Resource Management Applications (IRMA) NPS Data Store reference is Great Smoky Mountains National Park Lidar Tiles.2016年，针对田纳西州东部各县级区域开展机载激光雷达航空扫描作业，获取地面高程的激光雷达（lidar）点云数据，点云密度约为每平方米8个点。2017年，针对北卡罗来纳州西部各县级区域开展同类作业，同样获取了密度为每平方米8个点的地面高程激光雷达点云数据。本要素服务（feature service）中展示的激光雷达瓦片，可用于检索大烟山国家公园（Great Smoky Mountains National Park）最新的激光雷达数据采集成果。其对应的资源管理应用集成（Integration of Resource Management Applications, IRMA）美国国家公园管理局（National Park Service, NPS）数据存储参考标识为：大烟山国家公园激光雷达瓦片。
