Inventorying linear assets– really high resolution orthos

I have been contemplating all sorts of varied uses of Structure from Motion techniques. One of those outputs, in addition to using sUAVs (drones) is just to orthorectify and generate 3D meshes from ordinary photos. This has really great potential for linear assets like streams and rivers, trails and roads. We’ll have to being to contemplate how we’ll use (and summarize!) the incredible amount of data and information that will suddenly be available to us, e.g. this subset of an orthophoto of a multi-purpose trail:
