Abstract
A GIS (Geographic Information System), is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data. In other words, GIS is the merging of statistical analysis, database technology and cartography that can be integrated into any enterprise information system framework. But despite all these advantages, geographic information systems that used in organizational structures, is faced with some problems such as lack of interoperability, business alignment, and agility. This paper first analyzes the connotation, model structure and main features of GIS and Service Oriented Architecture (SOA). Then we propose a service oriented GIS platform which uses SOA concepts as the basic architectural concept and employs OGC (Open Geospatial Consortium) standards to support GIS concerns in the organization. Our combinational approach, using features such as loose coupling, integrity, independence and etc., can overcome the most of GIS problems such as lack of interoperability, business alignment, and agility.
