NR 319 Exam Review Questions With
Correct Answers
What is geospatial science
What is geographic information systems - ANSWER Measurement, analysis, and
presentation of geographic information
A tool that provides spatial framework to capture, store, manipulate, analyze,
manage and present geospatial data
What are the components of geographic information systems - ANSWER
Geographic: Data on some location in space
Information: Attributes of the data to provide insight into a given location
System: A seamless operation linking the information to the geography.
(Hardware and software)
Explain the difference between the toolbox, database, and organization of GIS -
ANSWER Toolbox: A powerful set of tools for collecting, storing, and retrieving
spatial data from the real world
Database: A system in which most of the data is spatially indexed to answer
queries about spatial entities in the database
Organization: An automated set of functions that provides professionals with
advanced capabilities for storage, retrieval, manipulation of display of
geographic data.
What are the six components of gis - ANSWER Database, Software, Hardware,
Network, Management/procedures, and people
Explain how GIS has evolved - ANSWER GIS has developed from integrated
projects, to coordinated systems, to cooperative networks, to collaborative
societal functions
What are the general steps of GIS - ANSWER Input of data
, Modeling of data
Creation of an output based off the modeling
What is cartography? - ANSWER the science that deals with the construction,
use, and principles behind maps
What are the five cartographic principles - ANSWER Maps
Scale/Resolution
Coordinate systems
Cartographic designs
Projections
What's the difference between physical, thematic and political maps - ANSWER
Physical: topographic
Thematic: Emphasizes a theme like roads of vegetation
Political: Country, state, county boundaries
How do you calculate scale on a map - ANSWER Scale =map distance/ground
distance
What are the three ways we can express a map scale - ANSWER Ratio (1:24,000)
Verbally (2.54 inches to a mile)
Visually (Scale bars
Difference between small and large scales - ANSWER Small scale: Less detail
over a larger area. Denominator is a bigger value and the map is more zoomed
out
Large scale: More detail over a smaller area. The denominator is a smaller value
and the map is more zoomed in.
What is marginal information and where can you find different information -
ANSWER Marginal information is information about the map that is found outside
of the neatlines. Information can be found on the top sides and bottom of the
map
Top: Author title, adjacent quads
Sides: Tic Marks (Coordinates) and Adjacent quads
