A Geographic Information System (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. With the advancement of technologies and internet it allows for the emerging of GIS to be considered as a WebGIS. In order to build a WebGIS for connecting to geo-data sources the authors need commonly acceptable standards for understanding of Web interfaces. OGC standards (WMS and WFS) for Web services interfaces and data interchange are used in WebGIS. For Data access and exchange, the OGC (Open GIS Consortium) WFS is used to access and manipulate feature-level data. The main advantages of this approach are interoperability and feature-level data sharing.
