GIS tutorials

Welcome to the GIS for Landcare video tutorial series. In these tutorials you will learn how to use the open source mapping software QGIS for the purpose of environmental conservation and Landcare. Most of the techniques and concepts covered in the tutorials can also be applied to other applications of GIS. The videos are usually around 10-15 minutes long and are accompanied by some written notes detailing the main points covered.

Important notes:
By design, the videos are recorded without sound. Please follow the on-screen captions.
QGIS software versions are regularly updated, and consequently the version that appears in the video may be slightly older than the version you are using. Most of the steps demonstrated in the videos will be the same regardless of the software version.\

Your questions and feedback helps us to make the videos as useful as possible. Please contact us if you have any questions or suggestions: http://www.nillumbiklandcare.org.au/contact
Stay tuned, more videos are coming soon!
