Lab 5 Introduction to Maps

Question 1

National Topographic System (NTS)

Answer 1

• Have unique names (number and letter)

- Pretty much the same

Question 2

Large-scale and small-scale (fractional)

Answer 2

• LS: 1:20 000 - small range means zooming in more to one area
• SS: 1:1 000 000 - large range by zooming out to cover a large area

Question 3

Prime Meridian Location

Answer 3

Through Greenwich, England

Question 4

Y and X co-ordinates for UTM

Answer 4

• Y: 0 at equator and extends to 10 000 000 at North Pole

- X: assigned 500 000m at each centre zone and extends from 0 to 999 999 on either side (avoins negatives)

Question 5

Find relief

Answer 5

• Find the highest elevation
• Find the lowest elevation
• Subtract two numbers to find relief

Question 6

Calculate slope

Answer 6

• Determine the elevation difference between the two points
• Use horizontal scale to find distance between two points (straight line or curved line)
• Divide vertical dist by horizontal dist to find slope

Question 7

Determining vertical exaggeration

Answer 7

VE = horizontal scale / vertical scale

Question 8

Making profile maps

Answer 8

• Choose line on map to draw profile of
• Trace the edges of the contour lines on a piece of paper
• Mark elevations along the top of the page using for the profile graph
• Draw the lines connecting the elevations marked
