Abstract

The need of spatial data sharing is increasing with the rapid urban expansion. However, the methods for spatial data sharing have not been well developed so far. In this paper, we establish a tri-layer geoinformation service framework using the Grid, SOA and web service. First, we integrated three modes that use geoinformation, which were: 1) the simple mode of viewing spatial data, 2) the analysis mode of querying and analyzing geoinformation, and 3) the peer mode of complex computing capabilities. Second, we designed a reasonable, flexible architecture of geoinformation service according to the three modes and expatiated the principles of each part. Then we argued that the middleware should be context-sensitive to provide intelligent services. We also discussed how to decide context detailedly and illustrated the principles of context-sensitive middleware. We found that the service-oriented grid architecture could realize data sharing and service more smoothly and accessibly.
