The difference in elevation between 2 contour lines. On topographic maps each contour line connects points at the same elevation.

Look carefully at the sample map. The intervals are increasing therefore the contours indicate a hill. Pplementary contour lines do not CONTOUR INTERVALS Printed below the bar scales in the middle of each map is the contour interval.

What is the difference in elevation between index contours. Be sure you set your compass before you begin. Maps changing topographic contour intervals.

The next two maps will illustrate some additional interpretations of contour lines. Give the correct answer or letter for each question. Largest scale map printed.

The contour interval is 5 feet and the highest point elevation 760 feet is located near the center of the map. The numbers 25 and 36 are related to the Public Land Survey System. 1 inch 2000 feet.

What is the contour interval of the map. Geolab 9 - Exercise Using a blank sheet of paper trace Map 1. How many feet are there in an inch on a map if the scale is 112000.

You should review a brief power point presentation about topographic maps A Topographic map shows the variations in elevation of the area represented on the map with contour lines. What is the fractional scale of the topographic map. The elevation for each contour line is sometimes marked on the line.

The contour interval of the map is 25 feet and the index contours are every 100 feet. Contour Interval bottom center of the map Contour interval is the difference in elevation between two adjacent contour lines. Possible contours include 500 520 540 560 580 600 620 etc.

Different maps use different intervals depending on the topography. What is the Bruton compass used to measure. 30 November 2012 Determine Hilltop Elevation To determine the elevation to a hilltop add one-half the contour interval to the elevation of the last contour line.

You can estimate or determine the elevation of a point on a map by following the steps indicated below. For example if your map uses a 10-foot contour interval you will see contour lines for every 10 feet 3 meters of elevation lines at 0 10 20 30 40 and so on. The contour interval of the map is 25 feet and the index contours are every 100 feet.

We call this spacing the contour interval. Because the stream flows south contour a which lies downstream of contour b must be the lower of the two. On USGS maps contour intervals are usually 1 5 10 20 40 and 80 feet.
