Good idea but - I would like to urge some degree of caution on this in the UK. In north-west Hampshire a year or two ago, someone erroneously added a series of footpaths from aerial imagery, which turned out not to be footpaths but maybe hedges or drainage ditches. Same happened in the Fareham area of Hampshire in around the same time scale. So if you're deriving footpaths or tracks from aerial imagery, please only add them if it is *absolutely obvious* that they are paths or tracks. Thanks, Nick
