Generation of Dtm from Stereo High Resolution Sensors
Digital terrain models (DTMs) were extracted from high-resolution stereo images (SPOT-5, EROS-A, IKONOS-II and QuickBird) using a three-dimensional universal physical model developed at the Canada Centre for Remote Sensing, Natural Resources Canada. DEMs were generated using an area-based multi-scale image matching method and then compared to 0.2-m accurate lidar elevation data. Elevation linea...
متن کاملQUALITY ASSESSMENT OF HIGH RESOLUTION RADAR DSMs
Radar remote sensing has a significant role in remote sensing technologies and develops rapidly. A series of new synthetic aperture radar (SAR) satellites has been launched to space having various operation modes which offer different resolutions and advantages. A very actual SAR satellite is German TerraSAR-X (TSX), launched on 15 June 2007. This satellite is a revolution for the SAR technolog...
متن کاملPhotogrammetric Perspectives on Challenges/developments in Mapping from Very High Resolution Imaging Satellites
Photogrammetric mapping has moved from its classical objective, which is the process of reconstructing objects from analog frame cameras to more contemporary objectives such as automatic generation of spatial and descriptive information from digital imagery. The advent of Very High Resolution (VHR) imaging satellites opens new challenges and potentialities to geo-spatial mapping community, espe...
متن کاملVery High Resolution Stereo Dtm Extraction and Its Application to Surace Roughness Estimation over Martian Surface
We have developed a processing workflow to extract very high resolution DTMs up to 0.5-4m grid-spacing from HiRise (Kim and Muller, 2007) and 12-18m gridded DTMs from CTX stereo pairs. This workflow relies on combining these data with the outputs of the UCL HRSC stereo processor, which is capable of producing 30-100m DTMs. This provides a unique capability to observe Martian topography at multi...
متن کاملAdvanced Dtm Generation from Lidar Data
The introduction of laser scanning has triggered off a revolution in topographic terrain capturing, especially in the generation of digital terrain models (DTM). In this article refined methods for the restitution of airborne LIDAR data are presented which have been developed at the Institute of Photogrammetry and Remote Sensing (Institut für Photogrammetrie und Fernerkundung, I.P.F.) at Vienna...
