WebThe deviation of the compass from true north is an angle called "declination" (or "magnetic declination"). It is a quantity that has been a nuisance to navigators for centuries, especially since it varies with both geographic location and time. It might surprise you to know that at very high latitudes, the compass can even point south!

WebAug 10, 2024 · For example, low points adjacent to the main channel are often abandoned, creating relic channels in meandering rivers. One technique used to study these topographic variations is the creation of a relative elevation model, or REM. An REM is created by removing the overall downward trend in river elevation, leaving behind the local …
