Geographic data sets are often very large in size. Interactive visualization of such data at all scales is not easy because of the limited resolution of the monitors and inability of visualization applications to handle the volume of data. This is especially true for large vector datasets. The end user's experience is frequently unsatisfactory when exploring such data over the Web using a naive application...
A variety of free, open source GIS tools is now available for geo-related processing. The Web processing service (WPS) uses Web service technology for spatial calculations or easy access to models on the Internet in contrast to traditional geospatial processing, which is standalone, inefficient and often requires purchase of expensive software. A number of standards-compliant geospatial Web services...
With tremendous increase in data from earth and space based sensors, there is growing realization within geoscience community that technologies like Web services and allied technologies need to be leveraged for geospatial data analysis and management. Traditionally, standalone geographic information systems software was used for these tasks. Adaptation of this software for use in Web services raises...
The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor has provided valuable information on various aspects of the Earth System since March 2000. The spectral, spatial, and temporal characteristics of MODIS products have made them an important data source for analyzing key science questions relating to Earth System processes at regional, continental, and global scales. The size of the MODIS...
Geospatial data is playing an increasingly important role in many areas. But there are still many problems associated with the effective use of geospatial data. One is that geospatial data is usually large in volume and is archived at geographically distributed data centers. Another is that the low-level geospatial data contains raw data instead of information that can be directly applied by users...
