May 19, 2016 at 12:20 comment added Ant6n What about trying to get a kml of an underground subway tunnel, where no GPS is available, while riding the train?
Apr 3, 2014 at 6:09 comment added Brendan Heywood Yup exactly. These are commonly hand draw in guide books and quality is pretty variable. I don't want to get down into the SDK land, I'm after a generic mobile app that you just turn on and start recording a line exactly like most GPS apps like MotionX. Then locate those recorded shapes as best as possible and export as KML / GPX, or worst case just a shape in SVG etc. Same app would have have heaps of uses like domestic surveying. Being able to record a high fidelity shape, even with a low fidelity location, and then open in Sketchup / google earth to fine tune then export again would be gold
