Orientation and Dem Extraction from Alos-prism Images Using the Srtm-dem as Ground Control
This paper presents a methodology of image orientation and DEM extraction from ALOS-PRISM stereopairs without the use of GCPs. It uses the approximate geo-location information derived from the sensor navigation instruments and the SRTM-DEM. The method consists in the extraction of a relative DEM, which initially is not correctly geo-referenced. This relative DEM is then matched to the SRTM-DEM,...
متن کاملReconstruction of 30m Dem from 90m Srtm Dem with Bicubic Polynomial Interpolation Method
This work presents a methodology for the refinement of 90m digital elevation model (DEM) of Shuttle Radar Topographic Mission (SRTM) data. The SRTM DEM is publicly available through the Seamless Data Distribution System (SDDS) at two resolutions: 30m for the United States, and 90m for the areas between 60N and 56S of latitude including the US. The selected test areas stretch eastwest from gentl...
متن کاملInSAR Kalman Filter Phase Unwrapping Algorithm Based on SRTM DEM
PU (phase unwrapping) is the key step and important problem in DEM (digital elevation model) extraction and the measurement of surface deformation of InSAR (Interferometric synthetic aperture radar). The CKFPUA (conventional Kalman filter phase unwrapping algorithm) can obtain reliable results in the flat terrain areas, but it caused error transmission not making the accurate inversion of surfa...

متن کاملUse of the Srtm Dem as a Geo-referencing Tool by Elevation Matching
This paper presents a methodology for planimetric adjustment of elevation data to the SRTM Digital Elevation Model (SRTMDEM), by correlation. It can be applied to geo-reference any geographic dataset with an elevation component, such as rasterised maps with contours or DEMs. The accuracy around 5 meters was achieved by this geo-referencing method assessed using elevation data from Portugal deri...
