In introductory geoscience courses, a profile is appropriate when you are asked to construct a cross-section. Topographic profiles are used to understand what a topographic map is telling you in a specific area (or, you can think about it as giving you a "side view" of the landscape along a specific line on the map). Interestingly, many geologists ...
Examine the topographic map image to the left (you can click on the image to make it larger, or you can download the map and a profile (Acrobat (PDF) 2.3MB Jul18 11) to try the steps below on your own). Before you start, you might want to review some of the rules about topographic maps (you can find rules at Idaho State U.'s field exercise, U. of M...
Topographic profiles are used in many applications in the geosciences. Some of the topics where you will need to recognize and draw a topographic profile are: 1. topographic maps 2. earthquakes 3. structural geology (and geologic cross-sections) 4. glacial geology 5. coastal geology 6. geomorphology
Several universities have tutorials on how to construct a topographic profile. Here are just a few: 1. University of Wisconsin, Stevens Point, has a flash animation to walk you through the construction of a profile. 2. Idaho State University has step-by-step instructions for constructing a topographic profile. 3. University of Texas at Austin has s...

Aug 31, 2019 · If the topographic map in Figure 3.6 has a fractional scale of 1:12,000 then 1 inch is equal to 12,000 inches or 1000ft; this 1inch = 1000ft equivalency is for the horizontal scale. When we hold a ruler to the y-axis of the topographic profile in Figure 3.6, we see that 0.5 inches = 50ft, which means 1 inch = 100ft on the vertical scale.
To graph out topographic profiles, you will have to enable the 3D extension. You’ll also have to add the 3D toolbar. The interpolate line lets you draw a line to analyze the slope and create topographic profiles. You’re going to start drawing a line where you want the elevation profile. We free-hand the line across the meteor crater.
If needed, tape paper together to a long enough sheet; make sure the grid lines line up. On the graph paper, draw a horizontal line the length of the profile line. Draw vertical lines above your starting and ending points. Label the y-axis (vertical lines) with elevation. It is important to consider the scale, use the noted highest and lowest ...

To begin constructing the topographic profile, take a strip of paper and align its edge along line A-A’ on the topographic map. At each intersection point between a contour line and a stream, place a tick mark on the paper’s edge. Simultaneously, record the elevation value corresponding to each contour line next to its respective tick mark.
