ASSESSMENT OF THE QUALITY OF DIGITAL TERRAIN MODEL PRODUCED FROM UNMANNED AERIAL SYSTEM IMAGERY
Unmanned Aerial Systems Aerial Imagery Digital Terrain Model Assessment of Quality Application
2016/7/5
Production of digital terrain model (DTM) is one of the most usual tasks when processing photogrammetric point cloud generated from Unmanned Aerial System (UAS) imagery. The quality of the DTM produce...
DIGITAL TERRAIN ANALYSIS USING AIRBORNE LASER SCANNER (LIDAR) DATA FOR NATURAL HAZARD ASSESSMENT
DEM Thematic maps Aerial Survey Visualization Numerical Simulation Hazard Assessment
2015/12/29
The airborne laser scanner (LiDAR) adopted recently permits creation of a more high resolution digital elevation model (DEM). Since the airborne laser scanner can measure the elevation under vegetatio...
Automated Quality Control of Digital Terrain Models
Photogrammetry DEM/DTM Error Quality Correlation
2015/12/3
The paper demonstrates modified cross-correlation methods to detect height errors of DTM points based on stereo-pairs of aerial images. The usual cross-correlation method is extended using dynamic dim...

This paper looks into the latest achievement in the low-cost Unmanned Aerial Vehicle (UAV) technology in their capacity to map the semi-development areas. The objectives of this study are to establish...
Methodology of Cloud Height Estimation over Rugged Terrain using Landsat TM Imagery
cloud shadow solar position scan direction ortho-rectificaation
2009/3/17
Horizontal distance between a cloud and its shadow appeared in a satellite image over flat terrain has been used to estimate the cloud height. This paper describes methodology of the cloud height esti...
