Sketch the Take time to review the descriptions to help you in preparing the map. Also note that the elevations for the survey points have been truncated and should be 58Xx feet. Coordinates most extreme points have been provided to help establish the scale of the drawing which should be noted on the completed drawing. 37 +829 N-5.926.98 E-5,324.17 +81.5 +82.5 83.1 57 +79.2 +81.4 36 +81. +78.3 +84.4 +80.8 +79.8 +77.5 FL +812 Toe +82.5 +79.7 T0B +78.9 +84.5 63 +82.6 +81.3 +77.1 +81.4 +78.9 TOB 81.3 +81.3 +26.6 +83.2 82.5 +83.9 +80.4 + 78.5 TOE +77.9 ??? +77.8 16 TOe +77.9 TOE +75.8 +786 +77.3 +78.6 +825 +81.6 +78.7 19 +78 +80. +70.0 ?

Explanation / Answer

1. Find the points having same elevation leval.

2. Draw the line joining the points having same elevation.

3. Please note that no contour will intersect each other.

4. U can take elevation of points between points given with scale.

5. U can take the scale as 0.5 m and at every 0.5 m elevation u will be getting a contour.eg. if you are starting with 76 m then u have to draw line having same elevation. next contour will have elevation of 76.5 and so on. Just keep in mind that no contour will intersect.
