I guess I'll just have to study up on the tech. IIRC there was a fairly quick LIDAR demo put on by a team at MIT that scanned the campus and surrounding areas in a relatively brief amount of time using a drone, I think.

My ignorance on the subject of LIDAR has me wondering why we can't use a faster traveling vehicle, or would it be possible to do perform scans with something like a fleet of balloons that stream the data back vs one static device.

Some rudimentary googling, MIT campus is 168 acres or .26 sq miles. So the 810 sq miles in 3 years is still pretty impressive.

MIT also has wifi. And power outlets.

LIDAR data requires precise location-information of the scanning-device, otherwise the data you collect is at best useless, and at-most wildly skewed. This is because all the points are in-reference to the location of the device. A faster traveling vehicle inherently means less-accurate location measurements.

Can SLAM be applied in this case?

It definitely can, though accuracy would always be a big concern.

IIRC, the Google self-driving car used LIDAR. Though their localization algorithms included many sensors, with the LIDAR data was just one of them.
