Integration of GIS:A showcase study on GML based WebGIS
The growth of Geographical Information Systems (GIS) emerges as analytical decision-making tools utilizing highly specialized geographic data.However,a simple system still does not exist for the integration/sharing information among GIS.Different organizations working within various domains have built their own data models for collecting and analyzing data.Many data storage,analysis,and delivery issues have prevented these organizations from effectively sharing their data.This presentation aims to show how to share the geo referenced information by utilizing GML (Geography Markup Language) technology among heterogeneous GIS.At present,the updates are retrieved manually;often failing entirely results in information loss and major inconsistencies or referenced data set can be purchased from geographic information producers.The problems and expense associated with the integration of updates for geographic databases are documented.Moreover,a showcase study on a GML based Web-GIS application system has also been developed in order to show how to share geographic information by using GML.The application includes various coverage layers online maps,important textual information and selected case studies
