The digital elevation model derived from SAR Interferometry is prone to atmospheric, penetration into soil medium, system noise and decorrelation errors. Eight ASAR images are selected for this study which have unique data set forming 7 InSAR pairs with single master image. It is expected that all the DEMs should have the same elevation values spatially with in the noise limits. However, they d...

The Japan Aerospace Exploration Agency (JAXA) has produced the world's first 10m resolution L-band SAR global mosaic datasets. These data sets were generated to monitor forest changes from the 1990s to present time. SRTM-3 (90m resolution) DEM was used for correct for terrain-induced SAR image variations and for ortho-rectification. Both corrections were applied for geometric and radiometric ca...

The objective of this paper is to provide an update on a program to create a single uniform DEM (Digital Elevation Model) for Western Europe and for the USA over the next two years. This program is referred to as NEXTMap and utilizes airborne InSAR (Interferometric Synthetic Aperture Radar) technology. In this paper the technology and the platforms with which this program is to be accomplished ...

DEM can be generated from a wide range of sources including land surveys, Photogrammetry, and Remote sensing satellites. SRTM 30m by The Shuttle Radar Topography Mission (SRTM), the Global Digital Elevation Model Advanced Spaceborne Thermal Emission Reflectance Radiometer (ASTER GDEM) global surface model called ALOS Worldview 3D 30 meter (AW3D30) Land Observing Satellite (ALOS) are satellite-b...

A large percentage of the Costa Rican territory is covered with high evergreen forests. In order to compute a 1″ Bare-Earth Digital Terrain Model (DTM) for Rica CRDTM2020, stochastic Vegetation Bias (VB) was reduced from NASADEM, Elevation (DEM) based on Shuttle Radar Topography Mission (SRTM) data. Several global models such as: canopy heights Global Forest Canopy Height 2019 model, year 2000 ...

Uzaktan algılama uygulamaları, aktif tektonik çalışmalarında yapısal unsurların belirlenmesi ve diri fay haritalarının hazırlanmasında saha çalışmalarına kolaylık sağlamaktadır. Bu çalışmada, Türkiye’nin en önemli unsurlarından biri olan Doğu Anadolu Fay Zonu’nun (DAFZ) orta kısmı konu edilmiştir. SRTM, Landsat 8 OLI ASTER gibi açık erişimli uydu görüntüleri uzaktan yöntemleriyle işlenerek rol ...

Shuttle Radar Topography Mission (SRTM) and Ground Penetrating Radar (GPR) data collected over an area north of the town of Hico, central Texas, have been used to map disturbances in the surface topography and subsurface stratigraphy. The Radar topography results confirm the presence of multiple rings suggestive of an impact crater. Correlation between the orbital SRTM and on-the-ground GPR fie...
