Managing a Geographic Database from Mobile Devices Through OGC Web Services

چکیده
We present in this paper a system for the management of geographic databases from mobile devices. The architecture of the system is extensible in the sense that it can be adapted to the particular characteristics of a wide variety of heterogenous mobile devices. This is achieved by the incorporation of an extensible middleware between the limited GIS applications running at the Mobile devices and the general purpose web services used at the data tier. The interfaces of these web services are compliant with the well-known Web Map Service(WMS) and Web Feature Service (WFS) specifications proposed by the Open Geospatial Consortium (OGC). A first prototype of the system for a specific PDA hardware with a specific software configuration was also implemented. We believe that the system has many practical applications in wireless environments with connectivity problems.

Integrating WebGIS with WFS and GML
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 geodata sources we need commonly acceptable standards for...

متن کاملNetwork 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 W...
