That's really cool! I've always wanted to map my yard and house like that, but I imagine it would be quite expensive. I'm on a hill and it would make it so easy to play around with landscaping ideas without having to measure a ton.
Also, it's crazy how easy it is to recognize homes from SF!
if you have a drone or have a friend with one, it's pretty easy to do this with aerial photogrammetry. Something like dronedeploy.com makes this very easy with a DJI drone.
Draw the area you want to capture as a polygon on google maps in DroneDeploy, deploy the drone, off it goes, takes the photos and lands without you needing to do anything. Then just upload the photos, and you get a 3d model processed on their servers an hour or so later.
