NETWORK PERSPECTIVE FOR SPATIAL DATA DISTRIBUTION ON WIRELESS ENVIRONMENTS

With regarding to web GIS, OGC promotes WFS allowing a client to retrieve geospatial data encoded in GML which is a modeling language to encode the semantics, syntax and schema of geospatial information resources. Even though GML provides benefits for geographic description, it is too heavy to be processed by mobile devices. In order to address the issue, this paper evaluates GML service with WFS server and GML viewers. Through this paper, we get analyses of properties of GML geospatial data and the effects on wireless environments, which are expected to be fundamental materials onto a design of mobile applications.
