Definition

Distributed geospatial computing (DGC) refers to the geospatial computing that resides on multiple computers connected through computer networks. Figure 1 illustrates DGC within the client/server (C/S) architecture (Yang et al. 2006a): where the geospatial computing is conducted by the geospatial components, which can communicate with each other or communicate through wrapping applications, such as web server and web browser. The geospatial components can communicate through application level protocols, such as the hypertext transfer protocol (HTTP) or other customized protocols.
