Any ideas on where I could find freely available college campus
footprint data? I'm looking for building footprints but also the
footprints of the campuses. I noticed that the basic google maps
layer has most college campuses shaded in grey and I'm wondering if
they got those layers from a publicly available source. If you know
where they got this (whether it was bought from someone like TeleAtlas
or another company, or whether there is a free repository for this
data somewhere) I'd appreciate a helping hand.
