I was looking at http://www.gelib.com/aeronautical-charts-united-states.htm, where you can download shape files for Google Earth that show US airspaces. I'm writing some software that has a similar need and need to find a source for this data. I'm looking for data that defines the extents of airspaces including MOAs, restricted areas, etc.
I have been pouring through the FAA's website with no luck. The link I referenced above says its source was the National Aeronautical Charting Office (NACO), which I'm having very little luck finding as well. I think it may have been renamed, thus the poor results. I also called the FAA and can't seem to find anyone there that knows where to transfer me.
So, does anyone here have any helpful pointers on finding said information? I want to pull it directly from the source to make sure it is always up-to-date and accurate.
