Abstract

Nowadays developing geo-metadata with the capacity for DATA QUALITY management and dissemination plays an important role in GIS/Geomatics world. DATA QUALITY information embedded in geo-metadata helps the users to decide whether the available dataset does fit the intended use. Standardized METADATA for geo-spatial data is a key in data sharing and finding information on the web and crucial in building Geospatial Data Infrastructure (GDI). The main aim in this paper was to develop a web-based geo-metadata dissemination system for IN-SITU SENSORs based on, most importantly, interoperable, standard and open technologies introduced by Open GIS Consortium (OGC) namely Geography Markup Language (GML). To do this research at first a use case diagram was developed to demonstrate the user's requirement. Then an application XML schema based on user's requirement was created. To build this schema some GML schema documents (developed by OGC) were imported into the application schema. System architecture was designed based on client/server model so a UML class diagram is developed to present all classes and their attributes, operations and associations within the system. Implementation was conducted using GML, XML, XMLHTTP, DOM, ASP, and VBScript that brought out a web-network-based IN-SITU SENSORs METADATA application. This application provided a user friendly interface to do search and find sensor related information. Based on this research it was found that although GML and XML are powerful tools to build geo-metadata and also embedded quality information but it is important to note that GML document size may be a problem when dealing with huge amount of data.
