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'm just a user of GPS and GoogleMaps/OpenStreetMap.

I don't have the maths to understand how they work, but am curious to learn.

Is there a good, newbie-accessible article that explains in simple terms how GIS work?

Thank you.
