W-09: Quantum GIS and PostGIS: Solving Spatial Problems and Creating Web-Based Analysis Tools 

Home > Workshops > W-09

Quantum GIS (QGIS) is a powerful open source GIS desktop application.  It excels at viewing and manipulating a wide variety of GIS data and services, performing geographic analysis and preparing data for MapServer and GeoServer applications.  QGIS has an extensible "plug-in" architecture and now provides comprehensive support for using and managing PostGIS databases.  This workshop/tutorial will give students hands-on experience for applying QGIS to real-world spatial analysis problems and the development of PostGIS tools for web-based mapping and services.

The first part of the workshop/tutorial will provide a brief overview of the QGIS interface and then have students run various GIS analysis tasks to solve real-world problems, access WMS and WFS services and create a MapServer configuration file.  After a short break students will learn how to manage and populate PostGIS databases, create their own re-usable GIS analysis tasks and how to deploy these tasks for MapServer-based mapping applications.  Time permitting, the plug-ins for creating terrain profiles, connecting to GPS devices and performing statistical analysis will also be reviewed.

Students should have some experience with other GIS desktop applications and possess a basic understanding of spatial databases and/or "Geodatabases".  Some experience with writing SQL database queries would be helpful but is not required.
