Generation of high precision DEMs of the Wadden Sea with airborne interferometric SAR
نویسندگان
چکیده
This paper describes how high-precision DEMs are obtained over the Wadden Sea using the AeS-1 airborne interferometric radar. The Wadden Sea is an intertidal zone along the coast which has height variations less than 5 m over 30 km and is free of vegetation. The resulting DEM has a grid spacing of 2.5 m and an absolute height accuracy of 5 cm rms, as verified by theodolite measurements. The paper describes the radar system, the processing techniques, the test area, the results, and the verification procedure. accepted for publication in IEEE Transactions on Geoscience and Remote Sensing, Vol. 38, Sep. 2000

COMPARISON OF DEMS FROM STAR-3i INTERFEROMETRIC SAR AND SCANNING LASER
Within the past few years there has been a significant increase in the use of Digital Elevation Models (DEMs), for applications as varied as telecommunications and precision agriculture, forestry and flood-risk assessment. Additionally, one may expect that externally-supplied DEMs will be used increasingly for ortho-rectification of high-resolution satellite imagery as it becomes available. The...
متن کاملQUALITY ASSESSMENT OF INTERFEROMETRIC SAR DEMs
A new interferometric SAR (InSAR) procedure for DEM generation was employed to generate different DEMs from ERS SAR image pairs. The procedure was validated comparing the InSAR DEMs with a suited reference DEM. In the first part of the paper the principal features of the procedure are briefly summarised. The second part is focused on the quality assessment of the InSAR DEMs. They cover the same...
متن کاملExperiences with Multiresolution and Multifrequency InSAR Height Model Generation
Interferometric synthetic aperture radar (InSAR) has become a broad field encompassing the use of both airborne and spaceborne sensors operating at a range of wavelengths and resolutions. This paper derives general conclusions from experiences at the Remote Sensing Laboratories of the University of Zürich with a variety of airborne and spaceborne InSAR sensors. Results from multiple systems ope...
متن کاملSpectral Diversity Methods Applied to DEM Generation from Repeat-Pass P-Band InSAR
Single-pass SAR interferometry is an established method for generation of precise digital elevation models (DEM). Although being a well established technique, it has one main disadvantage: At X-band, the penetration of the waves into vegetation layers is very small; the interferometric phase centre, which is measured by the interferometer, lies close to the top of the vegetation. An alternative...
متن کاملHigh Resolution Sar Imagery for Surface Deformation Assessment
The geodetic information of the terrain can be measured using remote sensing techniques such as photogrammetry, airborne laser scanner (ALS) and interferometric synthetic aperture radar (InSAR). They are considered to be more cost-effective and complementary to conventional ground-based surveying methods. Differential InSAR (DInSAR) can be further used to monitor the dynamic change of the terra...
