Open Source GIS 101, Part 2: GRASS

GRASS (Geographic Resource Analysis Support System)

Just as every skilled craftsman accumulates a variety of tools for the daily work, GIS professionals continually expand and evolve their software knowledge base.

While ArcGIS users are accustomed to working within the framework of Basic, Standard, and Advanced levels of licensing, open source GIS users gather their tools from a multitude of places. GRASS will be the first of the desktop applications this series will cover.

GRASS is the granddaddy of all open source GIS applications. With roots almost as old as ESRI’s ARC/INFO, it was originally developed by the U.S. Military as a tool for managing military-owned lands in the early 1980s. Today, GRASS’ software development is managed by a multinational team, licensed under the GPL.

GRASS is free, extremely powerful, and contains over 350 programs and tools for managing and analysing data. There is a learning curve for first time use; luckily, not too long ago, GRASS’ coordinator Markus Neteler uploaded this introductory full day workshop with videos. Plenty of supporting documentation is also available on the homepage, and there is a useful book on the subject.

If GRASS’ learning curve isn’t for you, fret not. The other upcoming software applications covered in this series are gui-driven and extremely user-friendly.
