6 days ago · Exercise 2: Determine Elevations from Topographic Maps a) In Figures 1 and 2, there is a red “X” marked on the North West Side of the map. Estimate the elevation of this point using the topographic map. It is _____ feet. b) In Figure 1, determine the following elevations. The highest point on Loring Hill is _____ feet.
A topographical map contains curved lines called contour lines. Each contour line corresponds to the points on the map that have equal elevation (Figure 1). A level curve of a function of two variables [latex]f\,(x,\ y)[/latex] is completely analogous to a counter line on a topographical map.
Topographic map diagram 2 . The topographic map above shows a hill with a peak elevation of 2574 feet above sea level. Four valleys and four ridges radiate from the peak. 1. Using a blue colored pencil, draw a line along the middle of each valley, showing where streams would run if there were a stream in each of the valleys.

Part 6: Contour Lines. A contour line (also known as a level curve) for a given surface is the curve of intersection of the surface with a horizontal plane, z = c. A representative collection of contour lines, projected onto the xy -plane, is a contour map or contour plot of the surface. In particular, if the surface is the graph of a function ...
Tape the overhead sheet to the top of the plastic lid. Place the lid on the box and then using a marker; trace the shoreline onto the plastic overlay (SEE BELOW). Remove the lid and add water until it reaches the next centimeter marking. Replace the lid and trace again. Maps Worksheet 2 L3. 9.

These marks should generally be at the same scale as the map (e.g., 1 cm per 10 m if the scale of the topographic map is 1:100,000). Place the profile paper between you and the line on the topographic map, with the x-axis of the profile paper parallel to the line on the topographic map (as shown in Figure 7.5).

Activity Sheet #4, page 3. Find the hill that rises steeply on one side and more smoothly on the other. On the topogrpahic map, draw a path up the gentler slope of the hill to the highest point. (Hint: remember that when contour lines are close together, the ground is very steep.) Draw a path showing a very steep way up the hill.
