COURSE CHARTING AND ANGLE MEASUREMENT
Use the navigational compass to chart courses on various maps:
- Place the compass so the starting location lies at the center of the tool.
- Ensure due north is set to 0 degrees.
- Rotate the red degree measurement line toward an intended destination.
- View the resulting degree measurement.
User sets the compass on a map and measures angles. Then the user switches to desktop mode to measure a map loaded in a web browser.
The tool can also be used to measure corners of buildings (an ordinary angle, an obtuse angle, an acute angle or a straight angle) and similar objects.
