In above Figure, what is the contour interval of the map? When the vertical dimension of your graph is different from the horizontal dimension on your map, you may end up with a graph that shows a vertical exaggerationand the features of the Earth represented by your topographic profile may be deformed such as in Figure 3.7. The Contour Interval of the above map us 20 Units. How were you able to come to this conclusion? The difference between adjacent contour lines. As a rule, hilltops will be slightly rounded to show a slight increase in elevation to represent the crest of the hill, but be careful not to draw the hilltoptoo high on your graph paper. You can figure out the elevation of Mathematically, a contour line is a curve in two dimensions on which the value of a function f (x, y) is a constant.

Be sure to only plot those elevations that are at the intersection of the contour line with line A-B. It is impossible to determine which location is higher. (Hint: Speed= Distance/Time). The contour interval is 20 meters ( Figure 10-2 ), thus each one of the intermediate contour lines crossed to get to point (a) adds 20 meters to the 500-meter index contour line. Want to create or adapt books like this? Figure 2 is based on a more complicated landscape that I contoured using a dark pen at a 10 m contour interval and using a lighter pen at a 5 m contour interval. of a hill (or hills). View Source. Creating If you examine the graph showing the topographic profile in Figure 3.6, can you imagine what would happen to your profile if we changed the spacing for elevations on the y-axis? Contour: Definition and Methods | Contour |Surveying Answered: 1. What is the contour interval of the | bartleby At 2900 Km the S wave velocity falls to 0. Contour lines Choose the appropriate profile below. For 1:25 000 scale maps the interval between contours is usually 5 metres, although in mountainous regions it may be 10 metres. It is south of Mammoth Cave. A standard topographic map uses contour linesto express elevations above sea level and show the shape of the land. Map Example slope percent = (120ft / 1000ft) 100 = 12% On large-scale maps with a lot of topographical detail, the contour interval is usually smaller, while on small-scale maps with less detail, the contour interval is larger. British Columbia Topographic Map 092G095. The highest point on a topographic map is marked as 345m. topographic profiles: Remember that topographic maps represent By using a ruler, you can transfer these elevation points from your topographic map straight down onto your graph paper such as shown in Figure 3.6.
