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 ...

Spectral remote-sensing indices based on visible, NIR, and SWIR wavelengths are useful in predicting spatial patterns of bare soil. However, identifying an effective combination informative or spectral for mapping soil a complex urban/agricultural region is still challenge. In this study, we developed new bare-soil index, the Hyperspectral Bare Soil Index (HBSI), to improve accuracy mapping. We...

Climate change and human activities have been heavily affecting oceanic inland waters, it is critical to a comprehensive understanding of the aquatic optical properties lakes. Since many key watercolor parameters Qinghai Lake are not yet available, this paper aims study spatial temporal variations water clarity (i.e., Secchi-disk depth, ZSD) suspended particulate matter concentration (CSPM) in ...

The characterization of vineyard soil is a key issue for crop management, which directly affects the quality and yield grapes. However, traditional laboratory analysis properties tedious both time cost consuming, not suitable precision viticulture. For this reason, fast convenient technique needed assessment management. Here, spectroscopy appears as alternative to assist analysis. This work foc...

abstract the assessment of ripeness is a major part of quality evaluation and depends on several factors such as soluble solid content (ssc), acidity and firmness. most of the methods that measure these qualities are destructive. so it is essential to develop an efficient and nondestructive method for measuring internal attributes of fruit. the objective of this study was to investigate visible...

• A band selection model - MSI for efficient and accurate vegetation mapping was described. Selecting principles: maximize separability of the target from other, information combinations. SWIR, NIR Red bands (with SWIR in particular) are effective separating mangrove other vegetation. is more suitable land cover extraction applications than full classification. described remotely-sensed cloudy ...

Accurate measurement of the radiative properties clouds and aerosols is great significance to global climate change numerical weather prediction. The multi-angle polarization imager (MAPI) onboard Fengyun-3 precipitation satellite, planned be launched in 2023, will provide multi-angle, multi-shortwave infrared (SWIR) channels multi-polarization satellite observation aerosols. MAPI operates a no...
