2018 Maryland Lidar: Ellicott City, MD

Products: This project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at an aggregate nominal pulse spacing (ANPS) of 0.35 meters (8ppsm). Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.3. The data was developed based on a horizontal projection/datum of NAD83...

项目涉及对激光雷达数据在0.35米（8ppsm）的聚合名义脉冲间隔（ANPS）下进行规划、采集、处理以及派生产品的制作。项目规范参照了美国地质调查局国家地理空间计划的基础激光雷达规范，版本1.3。数据开发基于NAD83水平投影/基准面进行。
