**Exercise 6- Calculating Slope from a Contour Map**

The two lines are perpendicular if the product of their slopes is -1 (i.e. m1 x m2 = -1) or one has a slope of 0 (a horizontal line) and the other has an undefined slope (a vertical line) i.e m1 = 0 and m2 = âˆž or m1 = âˆž and m2 = 0.... may find it easier to draw these if you first enlarge the map on a photocopier.) On completion, explain in a couple of On completion, explain in a couple of paragraphs any similarities and differences in the two cross-sections, and what this tells you about the terrain in each

**VERTICAL EXAGGERATION**

geostac@gmail.com April 8, 2008: Calculating a Slope. Determining the average slope of a hill using a topographic map is fairly simple. Slope can be given in two different ways, a percent gradient or an angle of the slope.... The "slope" of a vertical line. A vertical line has undefined slope because all points on the line have the same x -coordinate . As a result the formula used for slope has a denominator of 0, which makes the slope undefined..

degrees from the new vertical angle. In this example, the new angle is 120 degrees, so the slope angle is 30 degrees (120-90 = 30). To be as accurate as possible, you should sight along the protractorâ€™s edge to a point the same height above ground as your eye. (It helps to imagine someone of your height standing at the bottom of the slope.) Over a long distance, this discrepancy wonâ€™t... Measuring Slope Steepness. The easiest way to determine the percent slope of an area is to measure the change in height (elevation over a measured distance), then calculate the percentage of slope.

## How To Find Vertical Slope Geography

### 4. The slope of a line is called the gradient. It may be defined as: The change in vertical distance or elevation* over a given horizontal distance, or the change in horizontal distance over a given vertical â€¦

- Work out the vertical exaggeration of a cross-section if the vertical scale is 1cm represents 20 metres, and the scale of the map is 1:100,000. Work out the vertical exaggeration of a cross-section if the vertical scale is 1cm represents 50 metres, and the scale of the map is 1: 250,000.
- The slope at any point on one of these profile is the same as the corresponding slope on the ground only if the horizontal and vertical scales are the same. In most cases, however, it is both
- gives the slope angle in degrees in the ArcGIS Slope function. In physical geography, the orientation of the land surface is defined by its aspect, which is analogous to the azimuth used in land surveying.
- Finding Steep Slopes. Contour lines show us the change in elevation between points. If we find an area on the map where the elevation changes a lot in a very small space, that indicates a steep slope.
