Ditch Assist can display kml polyline features on the map. This may be useful to define features or to guide the operator where they need to cut a ditch or other feature. All that is required is a simple 2-dimensional kml polyline file (no elevation or other info is needed as the file is only displayed, we don't use it for anything else).

You can test that any kml files you generate will load and display correctly by downloading the Ditch Assist App and using the manage layers button to import them.
