Integration and Share of Spatial Data Based on Web Service

Integration and share of spatial information is a fundamental technology for Web based Geographic Information System (GIS), but it is difficult to implement due to the heterogeneity of spatial data. Therefore, we propose a web service based solution to facilitate the integration and share of spatial data. The solution utilizes Geography Markup Language (GML) to encapsulate spatial information, uses Web Service Description Language (WSDL) to describe XML Web Map Service (WMS) and the method for service publication and registry is introduced. Based on this solution, we develop a system with practical value in logistics information industry for its good performance in heterogeneous spatial data sharing and service integration.
