Hoping this is an easy one...
I want to build a web/mobile app for a college project which allows the user to enter a start point and a distance to travel e.g. distance to travel = 6km and the site would then plot a 6km circular route which brings the user back to where they started without (if possible) backtracking on any of the route already travelled.
I've been looking at OpenStreetMap and OpenLayers or Leaflet.js.
I'm not sure if this explains it very well but I suppose the app might work by calculating a 3km "end" point with a 1.5km waypoint on the east and a 1.5km waypoint on the west. Prefer to use open source technology.
I'm new to this so appreciate advice.
