Looking at contour lines helps you picture what a terrain feature would look like on the ground from a given distance. For example, if a map depicts a long, oblong hill with contour lines converging to a point
The top-left map shows an example of a hill/mountain structure – the contour interval on this map is 500 feet/contour line. As you start in the north-west (point A) and move south-east along the line you begin to increase in elevation from around 8500 feet at the start. You will ...
I focused on how to use Gaia GPS’s web browser interface to plan trips before heading out. This time, I’ll look at how to use Gaia GPS during the adventure itself—navigating your route, adapting to conditions on-the-ground, and using the app’s features to stay safe ...
Look in the margin of your map to find out its contour interval. To make topographic maps easier to read, every fifth contour line is an index contour. Because it's impractical to mark the elevation of every contour line on the map, the index contour lines are the only ones labeled. ...
If you have a printed map, look for the contour interval listed on the bottom. If you are looking at a digital map, you can usually click (or right-click) on a point to get the elevation based on the contour lines.Here's a flat topographic map laid over a Google Map 3D model. ...
On the topographical map below is a crater on the Moon. We want to determine the slope of the elevation difference between the two points listed (H =... Learn more about this topic: Map Projection Overview, Scale & Types from Chapter 2/ Lesson 3 ...

Put it this way, learning to utilize a map and compass develops you as an adventurer, while a reliance on technology actually deskills you. Technology is also fallible. Cold can wipe your device’s battery out with alarming speed, rendering you unable to navigate. Drop or lose your device ...
Topographic maps (topo for short) are a type of planimetric map, a map as observed perpendicular to the ground, like a birds-eye view. Planimetric maps contain symbols, roads, rivers, and other distinguishable landmarks but lack any way to determine elevation. Topo maps add contour lines ...
Knowing how to read a map is as basic to survival as knowing how to make a fire or how to build an emergency shelter, and that’s because it could be lifesaving in perilous scenarios. Maps and compasses keep us on the right track while helping us determine distance, time and the ...
