The quickest way to determine your location is to look for significant landmarks, both next to yourself and off in the distance. Next, lay the compass on your map so that the long edge/direction of travel arrow is aligned with the north-south meridian lines. Ensure that the compass bezel...
This is a "location by resectioning" technique where the bearing comes from a GPS instead of a compass sighting. It's useful when you are working on a map that does not have a coordinate grid. Lecture Slides - MapWithNoGridkeypptpdf ...
Theway you adjust for declinationvaries with different compass brands (some use a small tool) and you'll need to follow the provided instructions. Once the declination is set for a trip, you don't have to think about it again until you travel to a faraway place. 3. Orient Your Map Map...

Using device compass on the map, find your correct heading toward the target(destination). MyMap is to find the correct device heading to the target. While the app continuously displays current location with heading, the target can be set by 1. Latitude/Longitude or 2. Address, or 3. Reco...
There is no compass rose for orientation, no place names, no handy scale for distance ratios so that a reader might be able to tell how far one location is from another. There are barely even locations. Even the perspective is different—not a bird’s eye view, but something closer and...
