Heterogeneity of Geographic Information brought by
inconsistencies of the following aspects:
第 3 页
Is it possible to SHARE DATA directly and online instead of downloading, transformation or manually transfer?
Is it possible to SHARE processing algorithms directly and online, to get processing results (INFORMATION)?
Problem Statement
Is it possible to integrate distributed processing algorithms online to form a Geoscience model (KNOWLEDGE), and SHARE this model and the results of this model?

Geospatial Service Web (GSW) tries to provide a highly intelligent geospatial middleware that integrates various geospatial resources through the Internet based on interoperable Web services technologies.
The development of the GSW will focus on the establishment of a platform where data, information, and knowledge can be shared and exchanged in an interoperable manner.
