Water level fluctuations of inland lakes are related to regional-scale climate changes, and reflect variations in evaporation, precipitation and glacier meltwater flowing into the lake area in its catchment. In this paper, Ice, Cloud and land Elevation Satellite (ICESat) altimeter data and Landsat imagery (2002–09) are used to estimate Nam Co lake (Nyainqentanglha range, Tibetan Plateau) water ...

Estimating forest canopy height from large-footprint satellite LiDAR waveforms is challenging given the complex interaction between LiDAR waveforms, terrain, and vegetation, especially in dense tropical and equatorial forests. In this study, canopy height in French Guiana was estimated using multiple linear regression models and the Random Forest technique (RF). This analysis was either based o...

Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM), one of onboard sensors carried on the Advanced Land Observing Satellite (ALOS), was designed to generate worldwide topographic data with its optical stereoscopic observation. The sensor consists of three independent panchromatic radiometers for viewing forward, nadir, and backward in 2.5m ground resolution producing a triplet st...

In this study, the vertical accuracy of Shuttle Radar Topography Mission Digital Elevation Model Version 2.0 (SRTM30), Advanced Spaceborne Thermal Emission and Reflection Radiometer Global DEM (ASTER GDEM2), Land Observing Satellite World 3D Surface 2.1 (ALOS AW3D30) was statistically assessed using GPS data. The Fergana Valley area chosen as a study region, where land surface can reflect tecto...

[1] The discovery of hydrocarbon lakes in the polar regions of Titan offers a unique opportunity to compare terrestrial lakes with those in an extraterrestrial setting. We selected 114 terrestrial lakes formed by different processes as analogs for comparison with the 190 Titanian lakes that we had mapped in our previous study. Using the Shuttle Radar Topography Mission (SRTM) C-band backscatter...

The tectonic structures of the Mako area in Kédougou-Kéniéba inlier (KKI) were mapped with tele-analytical investigation which is validated by field data. This study based on different images processing particular: 1) colored combinations (1 to 5) and panchromatic (8) thematic mapping bands Landsat-8 (ETM+) satellite; 2) Digital Elevation Model (DEM) image Space Shuttle Radar Topography Mission...

Abstract Glacier surge is a special form of glacier displacement caused by the instability glacial dynamic system. It quasi-periodic oscillation behavior, which affects estimation overall change glaciers in region and potentially threatens infrastructure human life downstream regions. Most experience mass loss with rising air temperatures recent decades, but little attention has been paid to in...

In spaceborne dual-antenna (i.e., single-pass mode) interferometric synthetic aperture radar (InSAR) system, the alignment of the master and slave antenna beam is crucial. In order to achieve the best interferometric performance, antenna beams should be coincided with each other between the master and slave. The beam alignment of the first spaceborne dual-antenna InSAR system, the Shuttle Radar...

Digital Terrain Models (DTMs) used for the representation of the bare earth are produced from elevation data obtained using high-end mapping platforms and technologies. These require the handling of complex post-processing performed by authoritative and commercial mapping agencies. In this research, we aim to exploit user-generated data to produce DTMs by handling massive volumes of position an...
