An architecture for open and scalable WebGIS
نویسندگان
چکیده
This paper discusses an architectural model that is used in implementation of Ginis framework for realization of open and scalable Web-based geographic information systems (WebGIS). WebGIS system is considered as a whole that consists of a WebGIS portal and many Web-enabled GISs. For developing of all application components of an overall WebGIS, we introduced and developed unified model of geoinformation systems. Unified model leads to implementation of Ginis framework that further produces configurable GIS application components. Realization of systems using configurable components involves usage of explicit semantic descriptions of application domains for their configuring. For encoding of these semantic descriptions we defined Ginis Application Definition Language (GADL).

متن کاملAn SVG-based method to support spatial analysis in Web environment --Spatial analysis in XML/GML/SVG based WebGIS
This paper discusses how to provide spatial analysis for XML/GML/SVG based WebGIS. In recognition of current XML/GML/SVG based WebGIS’s insufficiency of providing spatial analysis, we focus on two important issues. First, based on the theory of spatial data modeling, we propose an SVG-based spatial information representation model to represent the needed spatial data in SVG on the browser side....
