How do I record a route that does not follow a mapped street or road? Fr example, hiking or canoeing on trails and rivers, or even city park paths? At work, it would be useful for measuring the lengths and elevations of all kinds of features of interest on the Google Maps aerial photos, but not mapped.
There's a radio button to the top left, with the heading "Draw route". Choose the "Manually" option, and it will place the point where ever you click it, drawing a straight line from the previous point.
