Frequently Asked Questions (FAQ)
Who are you?
I'm Robin Wilson, a freelancer in GIS, remote sensing and data science. For more information see my freelance website and blog.
Why did you create this?
I kept coming across GIS datasets online that looked like they might be useful - for my research, my friends research, or just for fun! I thought I'd keep a list of the ones that looked good - and then decided to put it online so that other people could benefit from it too. Fast-forward a few months and this is what you have: over three-hundred links, and hundreds of hits per day.
Where did you find the datasets?
A variety of places really. Some I knew about already, and some I had used in my research (or read about in the scientific literature). Others I came across online, particularly through GIS.SE and the GIS LinkedIn group. A number of items came from a wide-range of people who sent me links, asking me to add them to this site.
What are the requirements for a dataset in this list?
As you might guess from the title - I only list free GIS datasets here. That word is rather ambiguous (just ask Richard Stallman!), but here I use the meaning of 'free as in beer', and I include sites that provide data free for non-commercial purposes. Funnily enough, given the title, I don't link to datasets that cost money!
Is there anything I can do to help?
I'm glad you asked - of course there is! Three things really: you can tell your friends and colleagues about the site (see the Facebook and Twitter links on the top-right?), you can email me information about new datasets to link to (see below), and you can donate some money (see that button on the top-right?) to help me cover the costs of hosting this.
How can I contact you?
Email me at firstname.lastname@example.org and I'll get back to you as soon as possible.
Please don't email me about commercial datasets (I'm not interested) or to ask me if I can get hold of data on a particular topic. Every dataset I know about is listed on this site!
