Set Compass
is a Google Maps tool for the plotting and recording of compass bearings, distances and magnetic declination or variation for single or multiple Google Map routes.
Choose a single-leg or multi-legged route, use the search bar to select the starting point and Set Compass then overlays an interactive Silva compass on a Google Map. The compass can be dragged and positioned to point in any direction and routes can then be plotted.
The compass will automatically adjust for differences between magnetic and true north for any location and also provide the distances and latitude and longitude coordinates of your routes. Your Google Maps compass routes can be shared and saved for later retrieval.
