Hawaii DTM

Digital Terrain Model (DTM) for portions of the Hawaiian islands based upon lidar data collected by State of Hawaii and its data partners from 1999-2017. The DTM is a representation of "bare earth." The DTM is processed to digitally remove all surface objects including vegetation, leaving only the "bare earth," or underlying terrain. Elevation values are in meters.针对夏威夷群岛部分区域的数字地形模型（Digital Terrain Model，DTM），其数据基于夏威夷州及其合作数据伙伴于1999年至2017年间收集的激光雷达（lidar）数据。该DTM为"裸地表层"的数字化表征模型，经数字化处理移除了包括植被在内的所有地表物体，仅保留"裸地表层"即下方的基底地形。高程数值的单位为米。
