This is a screenshot from Google Maps' 3D mode. How would I go about "tracing" this; that is, accurately use it as a reference image to produce new geometry?

I'm assuming it will involve carefully setting the camera, matching perspective, etc. I also assume it will be marginally easier than it would be with a real picture, since I won't need to worry about lens distortion.

(Another option might be to attempt to actually extract the 3D data and use it directly; for now I'll assume that's not an option.)

I have Blender and Modo available, but looking for a general technique overview rather than package-specific steps.
Match camera, build blocks, detail scene.
>Match camera
Thanks anon, "camera matching" was the magic phrase I needed. I had been googling variations on "3d trace image perspective" without success.
Blender has a very useful addon for that called BLAM.
You could also extract the models from OpenStreetMap if the area you want to recreate is available in 3D. I'm pretty sure it's also possible to extract the models from google maps (it was a few years ago when I tried) but since their API keeps changing finding up-to-date tools might be hard.
i used to use glextractor but the quality is so poor I ended up doing it from scratc
