Got questions?

For any questions or clarifications about the topic of a tutorial, please leave a comment on that tutorial. I will try and answer that as quickly as I can.

For general questions on QGIS that don't relate to any of the tutorials, you can post them at and tag them with 'qgis'. That's is the official forum for QGIS users. I am user spatialthoughts in the forum.

For any other comments, or if you want to reach out to me, feel free to ask add me on Google+, twitter or email me at ujaval [at] spatialthoughts [dot] com
