	To convert this to something like TopoJson, I can use the TopoJson utility, which I installed as part of making my [[D3 Map]] (see http://charlesreid1.com/wiki/D3_Map#GeoJson_to_TopoJson).		==Shapefile to TopoJson==

			==Downloading Data==

			Selecting a location for which I wanted topological data, I faced the dilemma of not knowing which data set to select.

			I narrowed the view down to a specific region. I then clicked the download data link at the top.

			I was presented with an array of choices, and I chose "Contour" data. This gave me multiple shape files, two of which covered the region of interest. I went through the checkout process to download these two shapefiles.

			The region that I'm looking at is the Barry Goldwater Bombing Range outside of Yuma, Arizona, on the southwest Arizona-Mexico border.

			==Loading into QGIS==

			Here is what the shapefile looks like when loaded in QGIS... woah!
