Difficulties of Interoperability
Heterogeneity of Geographic Information brought by
inconsistencies of the following aspects:
 Data sources
 Data Models
 Supporting Systems
 Coordinate Systems

Problem Statement
 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)?
 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?

Conceptual framework - definition
 Geospatial service web is essentially a web service-based virtual
platform that integrates geo-spatial resource acquiring, intelligent
information processing, and knowledge discovering services,
with high performance computing infrastructure and sensor web
supported at the back end.

Conclusion
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.
