Quality checking of ALS Projects Using Statistics of Strip Differences
LIDAR Laser scanning Analysis Inspection Accuracy Quality
2015/12/8
We present an automatic method for checking the geometric accuracy of ALS points. First for each strip a DEM is interpolated using the moving planes method. The accuracy of the interpolated height at ...
LIDAR Data Reduction for Efficient and High Quality DEM Generation
LiDAR Laser Scanning DEM Interpolation Catchment Data Reduction
2015/12/8
Airborne Light Detection and Ranging (LiDAR) - also referred to as Airborne Laser Scanning (ALS), provides means for high density and high accuracy topographic data acquisition. LiDAR data have become...
Cartographic maps can only contain a certain amount of information. If the information density is too high, the map becomes hard to comprehend for a human viewer. A common solution for this problem is...
An Evaluation on the Data Quality of Srtm DEM at the Alpine and Plateau area, North-Western of China
