In component-based software development, it is necessary to measure the reusability of components in order to realize the reuse of components effectively. There are some product metrics for measuring the reusability of ObjectOriented software. However, in application development with reuse, it is difficult to use conventional metrics because the source(More)
We have designed Global Earth Observation(GEO) Grid, which is an infrastructure for archiving and processing huge satellite imagery and GIS geographical data sets. Users can immediately access the full archive and process the desired data areas on demand using the latest calibration and analysis algorithms through standardized web services interfaces on(More)
Synergistic applications of multi-resolution satellite data have been of a great interest among user communities for the development of an improved and more effective operational monitoring system of natural resources, including vegetation and soil. In this study, we conducted an inter-comparison of two remote sensing products, namely, visible/near-infrared(More)
We assessed the compatibility of three Advanced Spaceborne Thermal Emission and Reflection Radometer (ASTER) based Enhanced Vegetation Index (EVI) products generated in the GEO Grid system to Moderate Resolution Imaging Spectroradiometer (MODIS) EVI. The three products were two forms of the two-band EVI with ASTER red and NIR bands but without a blue band(More)
Rapidly changing environments of urban region impact local and regional energy balance, resulting in phenomenon of heat islands. One of the major factors is less amount of evaporative cooling by vegetation in cities than surrounding rural regions. Thus, a key to an estimation of mitigation effects by green vegetation is accurate retrieval of biophysical(More)
Understanding the impact of natural fractures in unconventional plays has been limited by the difficulty of describing fractures and intergrading this information from different scales. On one end of the scale, we have information from seismic that can allow the visualization of large fault systems or highlight areas of high tectonic displacement. On the(More)
National Institute of Advanced Industrial Science and Technology (AIST) developed an on-demand processing service on the GEO Grid system [1] to generate a Digital Elevation Model and orthorectified images from an ASTER data [2]. It is designed to support the latest algorithms for radiometric and atmospheric corrections developed by researchers as well as(More)
