Just noticed that photo geocoding app RoboGeo is up to version 3.4 — it can now export your GPS tracklog as AutoCAD 2000 DXF files (in addition to doing ESRI shapefiles, blogged previously).
What’s so special about DXF files? SketchUp supports them. This leads to some interesting possibilities. Thinking aloud, you could, for example, take geocoded pictures of existing buildings, and then try to recreate those buildings inside SketchUp using your tracklogged image locations as vantage points, for comparison. (Caveat: I haven’t tried this.)
