Yeah, looks like find edges. Could be a 3D technique which does the same thing, but highlights the lines for the 3D model/terrain - that would be done in the 3d renderer/engine, but you could do the same "scan" effect using find edges and a moving mask in AE:
load your footage into AE and drag to the timeline in your project
select the footage, duplicate it, then choose the effect (Effect >> Stylize >> Find Edges) - may want to adjust the effect-ed layer to give the right look
Add mask as needed to make the effect "move" through your footage.
