COMPARISON OF SEMI AUTOMATIC DTM FROM IMAGE MATCHING WITH DTM FROM LIDAR
Automatic DTM Image Matching LIDAR
2016/7/27
Nowadays DTM LIDAR was used extensively for generating contour line in Topographic Map. This method is very superior compared to traditionally stereomodel compilation from aerial images that consume l...
VOLUME BASED DTM GENERATION FROM VERY HIGH RESOLUTION PHOTOGRAMMETRIC DSMS
digital surface model digital terrain model multi-directional ground filtering
2016/7/27
In this paper we propose a new algorithm for digital terrain (DTM) model reconstruction from very high spatial resolution digital surface models (DSMs). It represents a combination of multi-directiona...
BARE-EARTH EXTRACTION AND DTM GENERATION FROM PHOTOGRAMMETRIC POINT CLOUDS WITH A PARTIAL USE OF AN EXISTING LOWER RESOLUTION DTM
Photogrammetry Point cloud DSM DTM Ground filtering Image matching
2016/7/27
A method of extracting bare-earth points from photogrammetric point clouds by partially using an existing lower resolution digital terrain model (DTM) is presented. The bare-earth points are extracted...

Pleiades 1A and 1B are twin optical satellites of Optical and Radar Federated Earth Observation (ORFEO) program jointly running by France and Italy. They are the first satellites of Europe with sub-me...
Digital aerial triangulation for DTM and orthophoto generation
Digital aerial triangulation DTM orthophoto generation
2016/5/20
Automatic Digital Aerial Triangulation has been implemented at the Institute of Geodesy and Cartography in 1997 on the ImageStation 6487 INTERGRAPH. Several blocks of B/W aerial photographs in the sca...
