The accompanying tabulation gives elevations of points over the area of a 50 m by 60 m tract of land. The elevations were obtained by the grid method using 10 - m squares. Point A – 1 is located at the northwest corner of the lot and point G– 6 at the southeast corner. All elevations are in meters. Construct a contour map using any horizontal scale with a contour interval of 20 meters. The proportional spacing of contour lines must only be determined analytically.

Analytical Method of Plotting Contours |
Transcribed Image Text:The accompanying tabulation gives elevations of points over the area of a 50 m by 60 m
tract of land. The elevations were obtained by the grid method using 10 - m squares. Point A – 1
is located at the northwest corner of the lot and point G– 6 at the southeast corner. All elevations
are in meters. Construct a contour map using any horizontal scale with a contour interval of 20
meters. The proportional spacing of contour lines must only be determined analytically.
