Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. It's 100% free, no registration required.

I wish to familiarize myself with the capabilities of QGIS.

I have downloaded the program, but apart from basic loading of data, I am lost (even after reading the help file).

Can you recommend me some good web resources and tutorials that would show me QGIS' capabilities?

I am particularly interested in developing applications using QGIS.

Here you have great manual for beginning: A Gentle Introduction to GIS Brought to you with Quantum GIS, a Free and Open Source Software GIS Application for everyone; by T. Sutton, O. Dassau, M. Sutton

Video lectures for that manual can be found here

  1. GISTUTOR.COM site offers well-made tutorial "step by step" with the information how to perform each task (not only about Qgis)
  2. On the Quantum Wiki there is section How do I do that in QGIS

I can highly recommend "the QGIS book" Desktop GIS: Mapping the Planet with Open Source Tools by Gary E. Sherman http://www.pragprog.com/titles/gsdgis/desktop-gis

The Geospatial Desktop book is revised version of the book you mentioned. –  radek Jan 24 '12 at 16:07

Check out the:

  • QGIS Manual - all features are described in detail
  • PyQGIS Cookbook - if you want to dive into creating python scripts and plugins

The Free QuantumGIS Training manual by Tim Sutton at linfiniti is excellent.

I have used and still use Ujaval's tutorials for almost all my tasks with QGIS. This page is highly recommended for those who are starting with QGIS along others who are more familiar. His tutorials are well connected and makes everything easier. –  Gus Velasco Aug 27 at 12:15

QGIS was my introduction to all of this, and I got my self started with the material on the QGIS site - http://www.qgis.org/en/documentation/manuals.html

The development of the software in recent months has left quite a lot of the third-party tutorial material behind but the changes have all been added features rather than a radical re-design so working through some of the older tutorials will give you a good grounding in the basics and prepare you to dip into the manuals when you're ready to do more adventurous stuff.

As you get more confident, its worth having a good GRASS reference to hand, like "Opensource GIS a GRASS Approach" by Neteler and Mitasova, and "PostGIS in Action" by Obe and Hsu (Manning).

And finally, its worth tracking the "QGIS Planet" blog for more technical and development stuff.

For QGis C++ development there is little information, but still here is what I've found:

-Official API doc

-GitHub code example (pretty old, 2008, if I'm not mistaken it's for QGis 1.8 and earlier versions)

-Coding Compilation guide (pretty old too. For Qgis 1.6, called before Quantum Gis)

-QGis C++ plugin development examples

A very good source is locate Press. The company specialized in books about the Qgis and GIS. It has some titles that have come out and some that are under publication and of course all is printed and e-book. The book of locate Press is:

  • The Geospatial Desktop Open Source GIS and Mapping The QGIS Training
  • Manual A Comprehensive Introduction to Quantum GIS
  • Geospatial Power Tools Open Source GDAL / OGR Command Line Utilities
  • The PyQGIS Programmer's Guide Extending QGIS with Python

I wouldn't recommend using sources from 2007. Too much has changed since then. –  underdark Nov 19 '10 at 8:04

And the web site is dead!! –  Vassilis May 3 at 8:37

I found this, but it seems to be a bit too old, but maybe it should be in this list anyways.
