NTERPOLATING CONTOURS GRAPHICALLY. The accompanying sketch shows a tract of land which has been subjected to a topographic survey. The elevation of critical points are as indicated in the sketch. Assuming uniformity of slope from corner to corner and from the center to each corner, plot the contour lines by the graphical method (use a template). The contour line with an elevation of 30m should be shown as an index contour and drawn about twice the thickness of the intermediate contours. Plot all the contour lines using a 2-m contour interval. Copy and enlarge the given sketch on a separate sheet of bond paper.

INTERPOLATING CONTOURS GRAPHICALLY. The accompanying sketch shows a tract of land which has been subjected to a topographic survey. The elevation of critical points are as indicated in the sketch. Assuming uniformity of slope from corner to corner and from the center to each corner, plot the contour lines by the graphical method (use a template). The contour line with an elevation of 30m should be shown as an index contour and drawn about twice the thickness of the intermediate contours. Plot all the contour lines using a 2-m contour interval. Copy and enlarge the given sketch on a separate sheet of bond paper.
