4/29 UE: Next Lab- by 10 points for each hour late Topographic Map Test-GOL 105 Name Part I: Construct a topographic map by contouring these elevations Start at 10 feet and use a contour interval of 10 feet. 2 n .51 50 25 ID Part II: Refer to the map on back to answer the following questions SHOW ALL WORK FOR FULL CREDIT on this sheet or on a separate sheet. 1) The numerical (ratio) scale on this map is inches) on this mapequals inch(es) on the ground. This means that 2) What is the elevation of Mount Trouble? 4) Calculate the gradient of Raging River from Point "x"to point "A."(Measure the distance along 3) What is the height of Mount Trouble? the "V's in the river) 5) The latitude at of the top of Mount Trouble is closest to 228 22 5 45°44 45° 40 6)For longitude, this map covers degrees minutes. (No decimals) 7) The longitude of point A (located at the mouth of Raging River) is closest to 8) What is the distance in miles between the top of Mount Trouble and Point A. 9) Which is steeper, South Mountain or Mount Trouble? Explain using the topographic map rules that 22 6 22 1 4535, 45 40 were covered in lab. 10) Raging River flows in the 11) Using twe contour line rules (see lab book), explain how you know the river flows in this direction direction (Be specific. eg NE, SW, etc). 12) Topographic Profile: Show all work for full credit. USE THE LINED SHEET PROVIDED. Construct a straight line topographic profile from the southwest corner of the map through the top of Mount Trouble to the edge of the map Remember to use the whole left margin of the lined sheet provided

Explanation / Answer

1. the numerical scale on this map is - 1:63360 inches ( where 1 mile = 63360, so we can say that 1 inch on this map is equals to 1 mile on the ground)

this means that 1 inch(es) on this map equals 63360 inch( es).

2. elevation of the mount trouble is 420 inches on tha map and in reality it will be = 420 * 63360 = 26611200 inches

4.. lattitude of the map is around 45' because its changing vertivally and longitude of the map is around 22' because its changing horizontally.

so the top of the mount trouble is closest to 45'44".

5. there is a difference of the longitude of this map is 15'. and the 1 degree og the longitude is equals to 4 min, so we can say that 1' is equals to 1 min or 60 seconds.

this map cover 0 15'00" and 1 minute.
