  • Your TA will provide brief comments where applicable, if you need more feedback you can follow up with your TA.
Score Category Details
0% Missing N/A
40% Insufficient Minimal effort, missing major key points, or serious logical flaws
60% Below Expectations Missing a few key points or minor logical flaws
80% Met Expectations Hits key points and mostly well constructed
100% Exceeds Expectations Clearly thought out, concise, and astute

File Uploads

Maps and file uploads will be evaluated for completeness following the rubric below. Later in term, maps will be evaluated for correctness and cartography. For now, as long as you can make a map with the necessary elements, you’ll get full credit!

Lecture Content Questions

1) What is redlining and what are some of its long lasting impacts?

2) A __ is a naturally occurring magnet. They were first used by the __ civilization in present day Mexico to orient their buildings and towns.

3) The __ projection revolutionized navigation because mariners could use it to navigate anywhere in the world by following a constant __. However, it is problematic for modern day use because it exaggerates the size of landmasses farther from the equator.

4) In your own words, what is belief perseverance? Give your own example of belief perseverance. This can be a historical example or one from your own personal experience.

5) The __ aimed to map lands in Canada based on their suitability for agriculture, forestry, recreation and wildlife. It was the first digital __.

6) The first step in creating an abstraction of the earth is to simplify it to a geoid. The geoid is an abstract representation of the earth that smooths out __ but preserves elevation differences due to __ differentials. Once we have a geiod, we can fit it to an oblate spheriod using either a local or global __

7) If you are mapping a city like Vancouver, a __ datum is best. When mapping the whole world, you’ll want to use a __ datum.

8) __ is a measure of angular distance North/South of the equator and __ is a measure of angular distance from the prime meridian. Together, they form a __, describing locations on the surface of a simplified model of the earth known as a __ which represents the earth as an oblate spheroid.

9) The Mercator projection should never be used to calculate:[Area/Distance/Bearing] . (select all that apply)

10) This type projection is great for displaying a small area like the city of Vancouver, but it should not be used to display all of Canada on one map.

  • Universal Transverse Mercator
  • Conic
  • Cylindrical
  • Planar

11) A map displaying UBC campus would be a __ scale map. A map displaying the whole world would be a __ scale map.

Lab Application Questions

12) Upload your Central_Wellington_Layout.pdf.

13) What does the select layer by attributes tool do?

  • Find features that meet specific criteria.
  • Find features that are in a specific area.
  • Find features based on their spatial relationship to other features.

14) A __ in ArcGIS Pro is a way to put a map on a page and map elements like a north arrow, legend, scale bar, and extent indicator.

15) What tool was used to create the 1500 meter zone around the campsites?

  • Buffer
  • Select by location
  • Intersect
  • Select by attribute

16) What is the first step when creating a new point layer?

  • Create a polygon feature class in the project geodatabase
  • Create a raster dataset
  • Make sure you are zoomed into your area of interest.
  • Create point feature class in the project geodatabase

17) Metadata is __ about __.

18) What does Project “On the Fly” do?

19) What spatial unit is the Shape_Area of the CAN_albersEA in? (hint check the Spatial Reference Info).

  • Meters
  • Kilometers
  • Miles
  • Degrees

20) What is the population density of the CAN_albersEA layer and how does it compare to the CAN_webMercator layer? Which layer do you think has the most accurate Population Density?

21) We are multiplying by 1000000 to convert the units to population per square __.

22) In your own words, what does georeferencing do?

23) How many cholera deaths were recorded in this outbreak? __ How many locations (points) are in the dataset? __ What is the highest number of deaths at one location? __

31) What do the mean center and directional distribution tell us about a set of points? Why might Kernel Density be more useful for identifying the source of a source(s) of a cholera outbreak outbreak than the mean center and directional distribution?

33) Upload your Kernel_Density.pdf.
