Shameless Plug: Contribute to digital cartography with OpenStreetMap
I've been trying to write an article for opensource.com for the last year dealing with open source cartography. I finally got around to finishing the article and it was published yesterday. I'm not exactly happy with the way it turned out so I'm hoping to do a part two discussing more than just the OpenStreetMap project and perhaps comparing various open source projects to those that are just crowd-sourced.
I appreciate feedback!
