Methods LIDAR Matching Error Transformation Three-dimensional Block
2015/12/8
For achieving high-quality LIDARgrammetry and performing surface reconstruction by 3D point clouds acquired at different locations or in different coordinate systems, a novel method was proposed and i...
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 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...
An Evaluation on the Data Quality of Srtm DEM at the Alpine and Plateau area, North-Western of China
DEM Shuttle Radar Topographic Mission (SRTM) evaluation Inferometric SAR (InSAR) land cover
2015/11/23
This paper evaluates the quality of SRTM3 data for alpine and plateau areas in Northwestern (NW) China against DEM data extracted from topographic maps. These SRTM data were obtained from both the ESR...
A Progressive Quality Control to Improve the Accuracy of LIDAR Data Processing
LiDAR Quality control Accuracy analysis Strips Adjustment
2015/11/20
Quick data acquisition using LiDAR, is a way to generate dense accurate DEM. The difference with an image recorded by a standard digital camera is that the LiDAR recorded points do not have a regular ...
