Deck 8: How to Perform Spatial Analysis in Arcgis Pro

Question 1

When examining the distribution of crime locations in an area, you perform a Moran's I calculation. A Moran's I value of 0.75 indicates the crimes are:

A) Evenly distributed
B) Random
C) Clustered
D) Uncorrelated

Answer 1

C

Question 2

A summation spatial join will append which of the following fields onto an attribute table after the join takes place?

A) Result
B) Total
C) Sum
D) Count

Answer 2

D

Question 3

The Getis-Ord G statistic allows you to determine:

A) The number of points that contribute to a "hot spot" in spatial analysis
B) The degree of randomness in a dataset
C) The total number of points that show properties of clustering
D) The degree of clustering in a dataset

Answer 3

D

Question 4

What makes a spatial query different from a regular Select By Attributes query?

A) A spatial query cannot return as many objects as a Select By Attributes query can.
B) A spatial query is based on location rather than attributes.
C) A spatial query can be performed only with a feature class, while a Select By Attributes query can be performed on any data type (i.e., feature class, shapefile, etc.).
D) A spatial query is more accurate in its results than a Select By Attributes query.

Question 5

Which of the following spatial analysis questions would be answered by performing a "summation" type of spatial join?

A) What is the total number of historic bridges in each county of a state?
B) What is the soil type that underlies a proposed road construction project?
C) What is the wastewater treatment plant closest to a new subdivision?
D) Within which county is a particular public swimming pool located?

Question 6

A spatial join can be used instead of a regular attribute join when:

A) The two tables do not have a common field
B) The two tables have more than one common record
C) The two tables have multiple common fields
D) The two tables are in separate data formats (i.e., one is a shapefile and one is a coverage)

Question 7

Hot spot analysis is used to:

A) Determine spatial clusters of high values and low values
B) Find the most "suitable" sites as the solution to a spatial analysis problem
C) Determine whether or not point values are clustered together
D) Find the values that recur the most often (are the "hot" values) in a dataset

Question 8

In a spatial join, the concept of "find how many wastewater treatment plants are within each county" would be which of the following join types?

A) Distance summarized join
B) Contains summarized join
C) Intersects summarized join
D) Inside summarized join

Question 9

Which of the following spatial analysis questions would be answered by performing a "distance summation" spatial join?

A) How many bridges cross a particular river?
B) What road is closest to a lake?
C) Which ranger station is closest to each campground?
D) How many schools are closest to each library?

Question 10

Which of the following Select By Location procedures is used to select the parcels that are completely or partially on the floodplain?

A) Are within a distance of the source layer feature
B) Are identical to the source layer feature
C) Contain the source layer feature
D) Intersect the source layer feature

Question 11

A spatial join represents which of the following?

A) Appending attributes from one layer to another based on the spatial relationship of the layers
B) Joining fields from the table of one layer to the table of another
C) Clipping the extent of one layer using the boundaries of a second layer
D) Merging two or more layers together using Catalog

Question 12

The answer to a query such as "Which culverts are contained within the county boundaries?" can be found by using which method?

A) Select By Attribute
B) Select By Coordinate
C) Select By Location
D) Select By Spatial Join

Question 13

When examining the distribution of crime locations in an area, you perform a Moran's I calculation. A Moran's I value of 0 indicates the crimes are:

A) Evenly distributed
B) Random
C) Clustered
D) Regionalized

Question 14

In a Select By Location query, "source" refers to:

A) The layer from which the query results will be drawn
B) The layer to which the query results will be found in relation
C) The layer that contains the final selected features
D) The layer from which one or more records will be retrieved

Question 15

In a spatial join, the concept of "finding the closest first aid station to a hiking trail" would be which of the following join types?

A) Distance join
B) Distance summarized join
C) Contains join
D) Contains summarized join

Question 16

Spatial autocorrelation refers to:

A) The strength of a relationship between two items (or variables)
B) The measure of the similarity of objects in an area
C) The distance for which occurrences stop affecting other occurrences
D) The percentage of similar events in an area

Question 17

Which of the following Select By Location procedures is used to select the weighted centers of land parcels within the boundaries of the floodplain?

A) Contain (Clementini) the source layer feature
B) Have their centroid in the source layer feature
C) Are within (Clementini) the source layer feature
D) Intersect the source layer feature
