Abstract

Abstract: The production of terrain-level geographic scene is one of the important tasks of Shandong pilot project of national new basic surveying and mapping system construction. As the main component of topographic-level geographic scene, DEM is generally produced by airborne LiDAR point cloud data. The surveying mapping institute of the author in is as a pilot area, and uses Leica CityMapper to obtain the point cloud data with aspacing of less than 1 meter, tests the flight quality and point cloud quality, and checks the point cloud vertical and horizontal accuracy. The Gaomi LiDAR project verifies the accuracy and efficiency of Leica the City Mapper, and it provides a technical solution for 1-meter spacing point cloud data acquisition and processing for Shandong land aera, and provides a guarantee for DEM and terrain-level geographic scene production.

Key words: new basic surveying and mapping, CityMapper, airborne LiDAR, point cloud, DEM
