This blog contains tips and tutorials on the tools and techniques we use as part of our research, which focus on remote sensing of vegetation. Many of the tools we use day to day we’ve developed ourselves (see software page) or have been developed by our collaborators (e.g., RIOS, TuiView) so a lot of posts will be about these. As a lot of time in remote sensing research is spent on data preparation tasks we’ll also include some useful bits of general computing we use, generally for UNIX-like systems such as Linux and OS X.

If you have questions about any of the posts, we have a google-groups mailing list: https://groups.google.com/forum/#!forum/rsgislib-support (note you need to be a member to post).
