INTRODUCTION

This course is intended to provide an introduction to spatial databases in general and PostGIS in particular to GIS professionals who are interested in expanding their skillset to multi-user enterprise level spatial databases. This course uses the latest versions of PostgreSQL, PostGIS, and QGIS.

COURSE OBJECTIVES

Upon course completion, participants should be able to:

• What a spatial database is and why you would want to use one.
• What SQL is, why you would want to use it, and how it can be applied to geospatial concepts.
• How to install PostGIS locally for development purposes and how to access a production version via a network or the internet.
• How to load your spatial data into PostGIS and access it from a variety of clients, especially QGIS
• The basics of SQL for both spatial and non-spatial queries
• How to validate data and control user access with the tools built-in to PostGIS
• Optimizing your queries for the best performance
• How to work with raster data in PostGIS
• The basics of programming custom functions with PL/pgSQL
• The basics of database administration to keep your database operating smoothly
