• TEST
• In your assigned lab period ONLY (Thursday or
  Friday)
• 2 hr time limit
• Description of test
• Types of questions

• Review of weeks 1-5
• Go over student questions

3
Student questions

• See handout
• I will go over as much as possible after slides
• Thanks for your input
• Come see me if you have questions
• Office hours Wed 100-300 pm or by appt.
• 2010 Ag Science

Test 1

• Covers ALL material through end of last week
• Does not include Wednesdays lecture on imagery
• Format
• 30 multiple choice, matching etc.
• 60 short answer (up to 5 sentences or so)
• 10 longer answer (two paragraphs or so)
• Worth 20 of your final class grade

5
Sample test questions

• Multiple choice
• Question X. Which of the following datasets
  would typically be stored in a vector data
  format?
• Aerial photo
• Streams
• Scanned topo map
• None of the above

6
Sample test questions

• Short answer
• Question. List four specific aspects of spatial
  data that may become distorted by using a map
  projection
• Answer Shape, area, distance, direction (SADD)

7
Sample test questions

• Longer answer
• Question. Based on the reading by Goodchild that
  talked about spatial uncertainty, as well as the
  lecture on spatial errors, describe at least
  three sources for spatial uncertainty. Next,
  describe how these forms of uncertainty might be
  avoided or minimized.
• Answer Make sure you list three (or more)
  logical sources of spatial uncertainty. They
  dont have to be exactly from the article, but
  they do need to make sense! Make sure you also
  answer the 2nd part, and describe how to get
  around them.

8
Sample test questions

• More open ended question
• Question In terms of cartography, what makes a
  good map?
• Answer Here I will be looking to see if you can
  communicate some ideas you picked up from the
  lecture and the lab exercise on cartography
  (both). Ideas from the readings would be great
  too!

9
Sample test questions

• Lab related questions Will not be on software
  specifics (like names of tools or tool options),
  but may cover general concepts / ideas behind the
  labs

Lecture 4. Map scale, projections
Example 1 inch (on printed map) 1200 inches
(on ground) map of stadium is 11,200 scale

• What is map scale?

• What are some common projections?
• Understand longitude and latitude coordinates
• Any other topics from slides
• Also see Exercise 2 (lab)
• Also see assigned required readings (USGS)

15
Lecture 5. Map accuracy, errors, metadata

• What is spatial uncertainty?
• What causes uncertainty or errors?
• Avoiding uncertainty
• Metadata (know definition and why it is used)
• Any other topics from slides
• Also see assigned required readings by Goodchild
  and FGDC (metadata)

16
Lecture 6. Spatial data resources

• Understand where spatial data comes from (many
  different ways to obtain it!)
• Be familiar with some of the standard national US
  datasets
• NED (DEM)
• NLCD
• Aerial photography (DOQ)
• Topographic maps
• Any other topics from slides
• Also see exercise 2, 4, 5

DEM
17
Lecture 7. Cartography

• Readings

You will not be responsible for supplemental
readings. The final project and final exam will
cover practical use of GIS (more lab knowledge).
