The document is about GeoGRID, which is a grid computing infrastructure for geospatial data. Some key points:
- GeoGRID was launched in 2005 and uses the ASTER satellite imagery archive (100TB) for geospatial data processing and analysis.
- It utilizes grid and cloud computing resources to process and analyze large geospatial datasets through open standards-based web services.
- Major applications include natural hazard monitoring, simulation modeling, and providing geospatial data and services to users.
The document discusses GEO Grid's activities during the 2011 Tohoku earthquake and tsunami in Japan, including providing satellite imagery, hazard maps, and geological data through online portals and services. It describes how GEO Grid established a disaster task force to process and deliver satellite data from NASA, JAXA, and other sources to support response and recovery efforts. Key services and data included satellite imagery of damage areas from ASTER, crustal deformation maps from PALSAR interferometry, and shaking maps from the QuiQuake system.
