GeoTecWorkshop2007

Abstract

This workshop features the creation of a complete spatial data management system using only open source components. The course materials will provide an overview of the PostGIS/PostgreSQL spatial database, uDig desktop GIS application, MapGuide Open Source Web mapping platform, and the FUSION AJAX framework. Participants will have an opportunity to install the software, load demonstration data, publish cartographic maps to the Web, use the desktop application to view and edit the spatial information, and publish the live data to Google Earth, all on their own laptop.

Spatial Data Management System
