Abstract

We report our experience in using GML for integrating heterogeneous geo-spatial datasets in building an experimental geographic information system (GIS). A GML application schema is developed to serve as an application profile that includes 1:1000 scale topographic maps, urban land-use zoning maps, and digital terrain models (DTM). In addition to using and modifying open source data conversion tools to transfer dgn-, shp-, and grd-formatted datasets to GML-coded documents, we have also developed our own query tools to retrieve collections of geo-spatial features from large GML documents. The retrieved collection of GML-coded geo-spatial features is rendered to SVG at the server-side and sent to the client-side for visual presentation and navigation.
