atmospheric correction of the satellite data, for example correction of visible and near-infrared spectral bands, requires removing the adjacency effect that is due to the reflection from contiguous pixels. To evaluate the accuracy of the ATCOR software atmospheric correction method of Terra/ASTER data (Jun 30, 2002) we compared the NDVI parameters taken from different sources, such as ground m...

ASTER stereo and ASTER infrared (IR) retrieved cloud top heights (CTHs) at 90 m spatial resolution are compared to operational Multi-Angle Imaging SpectroRadiometer (MISR) stereo and MODerate Resolution Imaging Spectroradiometer (MODIS) thermal IR techniques at 1100 m and 5000 m spatial resolution, respectively. ASTER data availability limits this study to trade wind cumulus clouds only. ASTER ...

Glaciers in High Mountain Asia (HMA) have a significant impact on human activity. Thus, detailed and up-to-date inventory of glaciers is crucial, along with monitoring them regularly. The identification debris-covered fundamental yet challenging component research into glacier change water resources, but it limited by spectral similarities surrounding bedrock, snow-affected areas, mountain-shad...

[1] A three-dimensional absolute velocity field on the isopycnal surface in the northwest Pacific subtropical region in the summer is calculated from the Navy’s Generalized Digital Environmental Model (GDEM) climatological temperature and salinity data on a 0.5 0.5 grid using the P-vector method. GDEM for the area was built from historical (1930–1997) temperature and salinity profiles. The basi...

As the impacts of global climate change, rapid economic development, and anthropogenic activities on environment are intensifying, it is becoming increasingly apparent that we need to understand ecological conditions their responses change human disturbances. The objective this study was present an assessment Kaikukang–Walagan District using remotely sensed index (RSEI) newly introduced integra...

A new Global Digital Elevation Model is being generated at 30" resolution by combining the best available ground truth with a unique global database of satellite altimeter derived heights. This model, ACE (Altimeter Corrected Elevations) demonstrates radically improved spatial accuracy and resolution over large parts of the globe, in particular over Africa and South America. The independent alt...

The aim of the study is to assess the limestone (LS) exploitation area and its negative impacts on natural resources using geo-spatial techniques. LS is an important constituent of cement manufacturing which is extensively used in the construction of infrastructure such as roads and buildings. The Margalla Hills National Park (MHNP) is situated around Islamabad and contains a large amount of LS...

We developed an on-demand processing service on the GEO Grid system to generate Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (DEM) and ortho-rectified images. The latest algorithms of radiometric and atmospheric corrections are also supported on this system (Sekiguchi et al., 2008). We implemented the MODTRAN3.7-based atmospheric correction for ...

TerraSAR-X add-on for Digital Elevation Measurements (TanDEM-X) mission is designed to generate 3-D images of the Earth as first bistatic synthetic aperture radar (SAR). However, few quantitative studies TanDEM-X digital elevation model (DEM) quality validation have been conducted specifically in China. This article presents an iterative method high-resolution DEMs and assesses vertical accurac...

An analysis of the landscape spatial structure and diversity in mountain ranges Northeast Siberia is essential to assess how tundra boreal landscapes may respond climate change anthropogenic impacts vast mountainous permafrost Arctic regions. In addition, a precise map required for knowledge-based territorial planning management. this article, we aimed explore enhanced methods analyse Orulgan R...
