GISP Actual Questions and Correct Answers
Q1
What are some ways generalization can be achieved in a map?
Answer: Aggregating - combining into a new composite feature Only selecting certain
features to be displayed Removing detail Dissolving/Merging (e.g. combine similar
neighbor elements) Exaggerating - make features larger than they are Smoothing out
detailed /complicated features (e.g. rivers do not need every curve)
Q2
What are some arguments why government-owned GIS data should be freely available to the
public?
Answer: Citizens should have access to information government uses in order to have
effective input into decisions. Costs can be prohibitive to any but very large
organizations. Government branches may horde data for bargaining power with other
agencies. Liability increased if data sold in commercial transaction. Research
opportunities lost due to expense Sales don't really recoup the costs for the agency
anyway. Distribution is cheap.
Q3
What are some basic trends in geospatial technology?
Answer: COMPUTING CAPACITY for Research, Apps EXPANDING Wireless and Web
NETWORKS REAL TIME Data MINIATURIZATION of Technology MOBILE Geospatial
Sensor PLATFORMS
Q4
What are the three general categories that temporal data may refer to?
Answer: DISCRETE events (e.g. lightning strikes) MOVING objects (e.g. trains)
REPEATED observations (e.g. counts from traffic sensors)
Q5
Data
Answer: symbols that represent measurements of phenomena
, Q6
What are some GIS-related work activities that are regulated by specific policies and
procedures?
Answer: editing, storing, and archiving data
Q7
Datum Shift
Answer: A change from one datum to another, such as from NAD27 to NAD83, which
can result in substantial horizontal shifts of point positions
Q8
What are the three main transfer constructs (based on data models)?
Answer: logical constructs solely pertaining to this standard constructs relating to the
implementation method constructs solely pertaining to the transfer media
Q9
Dot map
Answer: Uses uniform point symbols to show partial data, with each symbol
representing a unit value Create a visual impression of density by placing a dot or
some other symbol in the approximate location of the variable being mapped.
Q10
What is georeferencing?
Answer: Associating a map (eg pdf or jpg without spatial information) or image (e.g.
aerial image without spatial information) with spatial locations
Q11
What are the ways you can SELECT features based on ATTRIBUTE?
Answer: Add to Selection Clear Selection New Selection Remove from Selection Subset
Selection Switch Selection
