a grid-based architecture for earth observation data access
A huge quantity of Earth Observation (EO) and geospatial data is daily produced by several organizations. These heterogeneous data are very useful in several scientific, civil, military and industrial applications.Securely and transparently storing, managing and accessing this huge quantity of data spread over distributed systems is a challenging problem. Grid computing offers today a way to achieve secure access to geographically spread storage and computational resources.In this paper we present the Distributed Earth Observation System Information Service (DEOSIS) a distributed information service, developed by CACT/ISUFI at the University of Lecce which aims at managing and accessing EO and geospatial heterogeneous data sources, in a grid environment.
