You can find the gradient of a path using information from Google Maps, but it requires a little math on your part. To calculate the vertical gradient of point A to point B, subtract the elevation of B from the elevation of A, then divide the difference over the horizontal distance betwee...
Elevation acts as a basic yet efficient tsunami barrier. Aim for a place at least 100 feet above sea level. This altitude is generally considered safe from even large tsunamis. If you cannot properly estimate altitude, your goal should be to reach as high as possible because every foot of ...

First, you need to find out the declination variance from your map. Let's say it's 10° west. Start by taking a bearing as normal using your map, then, holding the compass fixed against your hips, turn your body until the red end of the compass needle points to 10° on the ‘W....
These thermal updrafts are relatively weak; to lift your larger human body, you’ll need to find a stronger source of rising air. Some of the strongest updrafts near the ground happen near mountain ridges. When wind encounters a mountain or ridge, the airflow can be diverted upward. In...
If you started your video recording while the drone was on the ground, you can use the fields namedSensorLongitudeandSensorLatitudeto navigate on the map to find the elevation of your launch point and follow the procedure described above. If the video started on the ground, the altitude ...

find your way out. A topographic map offers a wealth of orienteering information, too. It not only shows elevation and distance, but also human-made structures and changes in vegetation. There’s enough information on a topo map to plan an entire trip in advance and also find your bearings...
The following are a few aspects to understand before navigating: Contour lines: The thin (usually brown or black) lines on the map running hither and yon are known as contour lines. Each line represents a certain elevation above sea level. Typically every fifth line will be thicker and is ...
