GIS Stack Exchange

GIS Stack Exchange is a question and answer site dedicated to helping people figure out GIS (geographic information systems) problems. It’s part of a larger Stack Exchange network of Q&A sites about various topics.

I received some helpful replies in response to a query I posted earlier this year, and have found useful information there as a result of other searches, too. So, in an effort to “learn by teaching”, I’ve decided to try contributing answers on a regular basis (at least weekly). I’m not qualified to address most of the topics that come up, but there is a large backlog of unresolved questions to peruse, and I’ve already found a few of interest. Even if I can’t provide authoritative answers, I hope that providing pointers to relevant references might help people figure things out.

Here are the comments I’ve offered so far:

• Cartograms: making base maps and facilitating size comparison (previously, here)
• Shapefiles: clarifying whether polygon features may intersect themselves (no)
• Projections: finding an implementation of space oblique mercator (PROJ.4 supports a Landsat-specific subset; sparked some more ideas for gtg)

One of my answers even got an upvote! So, yay. My geography degree was good for something.
