Exercise 1.2:
Open the Lab 1 Digital Map: and answer the following questions. You may also access this map from Canvas. Go to the Santiago Canyon College Bookmark. Using the Measure Distance Tool, answer these questions:
1. The Red Pushpin is the location of the lab classroom. Imagine that you were to exit the building (Green pushpin) and walk to your car (Blue pushpin). You can only walk along the sidewalk until you get to the parking lot. How far is it in feet from the building’s exit to your car?
2. What is the difference in miles between Newport Boulevard and Jamboree Rd, if you were to drive along Chapman versus Santiago Canyon Rd?
How accurate are your measurements? Let’s find out. Go to the Valencia High School Bookmark and measure the length of the football field. Note: Football fields are 100 yards between the goal lines. I marked the goal lines in yellow on this image:
3. How close were you to the actual length?
Change the Basemap to Imagery and Return to the Santiago Canyon College Bookmark,
4. Using the measure area tool, measure the area of the field I labeled. How many sq. miles is it?
Challenge Question:
5. What percentage of our campus is part of the built environment? The built environment includes parking lots, buildings, sidewalks, and concrete areas. Basically, everything that is not grass or vegetation. How would you go about answering this question? What is the answer?
Part 2: Converting Units of Measurement
Exercise 1.3:
Show your work, but check your answers with an online conversion tool.
English System
1 foot = 12 inches (in)
1 mile (mi) = 5280 feet = 63360 inches
1 gallon (gal) = 4 quarts
Système International
1 meter(m)= 100 centimeters (cm) = 1000 millimeters
1 kilometer (km)= 1000 meters
1 kilometer = 100,000 cm =1,000,000 mm
1. 28 in * ft = ___________ ft
in
2. 6 km * ___________m = _____________ meters
km
3. 16 quarts = ___________ gallons
4. 0.25 meters = ___________ millimeters
5. 500000 centimeters = _________ kilometers
Practice converting between English System and Système International, using the following conversion factors. Show your work.
Conversion Factors:
1 kilometers (km) = .621 miles(mi)
1 kilograms (kg) = 2.205 pounds (lbs)
1 liter = 1.057 quarts
If given Celsius= (1.8 * °C)+32 ° = ° F
If given Fahrenheit = (° F – 32°) = °C
1.8
6. 100 miles * _________km = ____________ km
miles
7. 0.5 lbs * ________kg = _____________ kg
lbs
8. 4 quarts = _____________ liters
9. 13 ° C = _____________ ° F
10. 20 ° C = _____________ ° F
11. 77 ° F = _____________ °C
12. 50 ° F = _____________ °C
Part 3: Rounding
Exercise 1.4:
Round the following numbers to the nearest tenth.
1. 1.3556 = ______________
2. 21.4333 = _____________
Round the following numbers to the nearest hundredth (two decimal places).
3. 3.546 = ______________
4. 24.9312 = _____________

5. 24.589 = ______________
6. 12.158 = _____________
Part 4: Identify types of distortion on map projections
Exercise 1.5:
1. Map A is most likely which type of projection? Explain your reasoning.
2. Map B is most likely which type of projection? Explain your reasoning.
3. Map C is most likely which type of projection? Explain your reasoning.
4. Out of the three types of projections (Conformal, Equivalent (or equal area) or
Compromise), which projection would be the best for measuring the extent of a Tropical Rainforest? Explain your reasoning.
5. Out of the three types of projections (Conformal, Equivalent (or equal area) or Compromise), which projection would be the best for a general reference world map? Explain your reasoning.
Exercise 1.6:
