Ontology-based geospatial XML query system
Nancy Wiegand, Naijun Zhou, Isabel F. Cruz, William Sunna · International Conference on Digital Government Research · 2004
This demo illustrates querying heterogeneous geospatial data over the Web. The Geospatial community is in the process of developing Web sites that enable coordinated access to geospatial data. A new example is the Federal government's Geospatial One-Stop portal [GOS03]. The purpose of this Federal initiative is to have all geospatial data accessible from one site. There are many other examples of geospatial Web sites including the Wisconsin Land Information System [WLISsite] and the Alexandria Digital Library project [ADL]. These Web sites allow keyword search of data sets but do not have a query capability for full data manipulation nor do they accommodate heterogeneous data.
