For the advanced crowd (Alyssa and friends), you can perform analysis
using the GRASS plugin.
Pros and Cons
Let's look at some of the pros of QGIS:
• Support for a wide range of both vector and raster data
• Editing capabilities
• Good set of tools for symbolizing and visualizing your data
• Good documentation
• Strong community support through forum, mailing lists, and IRC
• Extensible through plugins
• Includes a plugin for working with GPS units
• Good integration with GRASS visualization, editing, and analysis
functions
• Customization using Python in order to write new tools and plug-
ins (requires version 0.9.0 or higher)
Here are a couple of cons:
• Simple feature labeling (no collision detection)
• Limited map composition and printing capability
• Doesn't include all features of a desktop GIS
• Still maturing
QGIS likely has a place in your visualization and editing toolbox, espe-
cially when you consider the wide range of formats supported, the inte-
gration with GRASS, as well as the extensibility provided by the Python
bindings.
