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...
The High Resolution Stereo Camera (HRSC) onboard the European Space Agency’s (ESA) Mars Express (MEX) has been orbiting Mars since December 2003. One of the main aims is to cover Mars globally in colo...
Detailed high-resolution digital terrain model can be obtained in open area using airborne laser scanning technique. But in forested area, how to extract high accuracy digital terrain model still need...
In Digital Terrain Models (DTM) interpolation is actually a surface fitting problem. For the estimation of heights of points with known X-Y coordinates there are many interpolation methods. Besides, t...
Cartosat-1 is the first Indian Remote Sensing satellite able to collect in-track high resolution stereo images with a 2.5m pixel size. Since Cartosat-1 has no multispectral cameras, it was mainly deve...
THE EFFECTS OF GIS ARCHITECTURE, DATA MODELS AND DATA SOURCES ON THE ACCURACY OF DIGITAL MAPS: AN EXAMPLE OF DIGITAL TERRAIN MODEL OF IBADAN REGION.
It’s noticed a significant increase in the development of orbital and airborne sensors that enable the extraction of three-dimensional data. Consequently, it's important the increment of studies about...
Currently, the Digital Terrain Model (DTM) and orthoimages have become standard geospatial products. However, photogrammetric systems used for generating them still remain desktop or workstation based...
