Not sure if this qualifies as an info graphic, but it's not a map so I guess this is the best place for it.
At the SGC we always struggle with getting researchers to understand the issues involved with the differences between accuracy and precision; as well as false precision with too many decimal paces in a coordinate; and understanding why we don't measure in geographic coordinates.
This single page graphic is my attempt to provide a quick reference or cheat sheet for those issues in GIS. I found a few simialr sheets around online but nothing that put it all together.
Let me know what you think. This is not a primer on projections and coordinate systems, that graphic is still under development!
