The sharing and interoperability of geospatial data are important issues for spatial information grid (SIG). Based on an existing SIG platform, we tentatively propose a three-level overview SIG layout. Within this new architecture, some grid service entities (GSEs) complying with Open GIS Consortium (OGC) interoperability specifications, such as Web Map Service (WMS), Web Feature Service and Web Coverage...
MODIS (Moderate Resolution Imaging Spectroradiometer) is an advance earth observation system, which is the world's best remote sensing data of free receiving. However, there is a serious problem about duplicated establishment of MODIS data receive station in China, and it has brought a tremendous waste of money. Utilizing data grid technology could take advantages to integrate and share heterogeneous...
How to manage and utilize huge amounts of spatial data more efficiently is very important for data sharing and applications. This paper presents the research work of a general model of data service in China Spatial Information Grid. This project is to provide a foundational infrastructure for sharing large quantity of earth observation data and earth science applications in grid environment. It is...
Every day, space missions involve the download, from space to ground, of many raw images that are stored in the ground station. These data are stored in geographically distributed and heterogeneous database systems, which make these resources access and share difficult. Data grid technique can hide the difference of storage systems and makes the isolated data resources be shared in the grid environment...
