چکیده
This paper has proposed GML-GIS, which is a prototype system for geographic information service over the Web based on GML (Geography Markup Language). This system generates geographic information into GML document by user requests through URL and provides them with various styles applied to the document on the Web browser. This proposed system converts geographic information of a spatial database into GML documents for interoperability of diverse GIS engine. The architecture of this system is composed of User Interface Module, CGI/Script Module, Application Schema Generator, GML Translator, XML Analyzer, and Documents Pool. By the usage of this system, general users can access easily geographic information of multiple data server with different data type by Web browser

Designing a Volunteer Geographic Information-based service for rapid earth quake damages estimation Introduction The advent of Web 2.0 enables the users to interact and prepare free unlimited real time data. This advantage leads us to exploit Volunteer Geographic Information (VGI) for real time crisis management. Traditional estimation methods for earthquake damages are expensive and tim...
متن کاملA multi-agent system architecture for geographic information gathering.
World Wide Web (WWW) is a vast repository of information, including a great deal of geographic information. But the location and retrieval of geographic information will require a significant amount of time and effort. In addition, different users usually have different views and interests in the same information. To resolve such problems, this paper first proposed a model of geographic informa...

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...
متن کاملAn SVG-based method to support spatial analysis in XML/GML/SVG-based WebGIS
XML/GML/SVG based approaches are promising for building Web-based geographic information system (WebGIS). However, current XML/GML/SVG based WebGISs are lacking in spatial analysis. Some of them are designed for web mapping only. Others adopt a server-side solution for spatial analysis, which suffers from the “bottleneck” problem, and results in a high network transmission load. Load balancing ...
متن کاملA Spatio-Temporal Query Language for a data model based on XML
The recent emergence of eXtensible Markup Languge (XML) as a new standard for data representation and exchange on the World-Wide Web has drawn considerable attention in the Geographic Information Systems (GIS) world. OCG (OpenGIS Consortium) is contributing with a XML specification to the representation of geographic information (called GML Geographical Markup Language). GML allows the exchange...
