minimizes.
1. Area - equidistant
2. Shape - conformal
3. Distance - equidistant
4. Direction - conformal - ANSWER 3. Distance - equidistant
Which of the following Is not part of the 5 principles of relational databases?
1. There is significance to the sequence of columns and rows
2. Each row is unique
3. There is only one value in each cell
4. All values in a column are about the same subject - ANSWER 1. There is significance
to the sequence of columns and rows
What is the difference between ecological fallacy and Modifiable areal unit problem? -
ANSWER Ecological fallacy is making inappropriate inferences or assumptions from
aggregate data about the characteristics of individuals and a modifiable areal unit
problem is the issue of scale and how aggregated data is a result of breaking shapes
apart spatially.
Projections and Coordinate Systems are used in the same way in ArcGIS. - ANSWER
False
All of the following are Classes of Projections except:
1. Conformal
2. Equidistant
3. Equal-aread.
4. True-directione.
5. Dispersal - ANSWER 5. Dispersal
, Which of the following best describes a positive spatial correlation?
1. Randomly spread blocks
2. Clusters blocks
3. Dispersed blocks
4. Blocks that are as unclustered as possible - ANSWER 2. Clusters blocks
In your own words describe the concept of an ecological fallacy. - ANSWER Ecological
fallacy is when conclusions are wrongly made about individuals within a group based on
that groups data.
The biggest challenge with GIS data is that we live on a sphere that we are displaying
on a flat screen!: - ANSWER True (could be interpreted as false, as we live on an
'ellipsoid.')
Only one value in each cell, all values in a column are on the same subject, each row is
unique, and there is no significance to the sequence of columns/rows are the 5
principles of relational databases. - ANSWER True
What is not a type of Spatial Autocorrelation?
1. Dispersed or Unclustered
2. Random
3. Undefined
4. Grouped Together or Clustered - ANSWER 3. Undefined
What does a spatial reference not need?
1. A map projection type
2. A datum
3. A coordinate system
4. A map description - ANSWER 4. a map description
Describe Waldo Tobler's First Law of Geography, and provide an example: - ANSWER
Waldo Tobler's First Law of Geography states that "everything is related to everything
else. But near things are more related than distant things." An example of such
occurrence is rain, where assuming one stands at a given spot, looking at a different
spot only a meter away is likely 'more related' than a place a kilometer away, given
proximity and time to events happening at one's original location.
Spatial autocorrelation says individuals are more likely to be similar while ecological
fallacy says the group does not always represent individuals - ANSWER True
Joining data is critical in GIS because it allows you to combine data together - ANSWER
True
The terms ________ and ________ are used interchangeably
1. A line and point
2. projection and coordinate system
