Intro to GIS Exam Questions with Correct
Answers | Updated (100% Correct Answers)
GIS Answer: System of hardware and software that links mapped
objects to attribute information
why use gis Answer: make assumptions and draw conclusions
aspatial data Answer: data that is not tied, or is only incidentally
tied, to a location on the earth's surface, ie. billing for a company
spatial data Answer: data with a discrete location and coordinates.
discrete data Answer: objects existed in a defined location, ie. lines
and points, uses vector data
Continuous Data Answer: data exists everywhere, ie. elevation, uses
raster
vector model Answer: each feature is linked to a data table in a 1
to 1 relationship, consists of points, lines, and polygons.
raster model Answer: breaks geographic areas into small cells or
pixels, stores continuous data. can also use reclassified discrete data.
geometric accuracy Answer: how closely x-y values of a data set
correspond to an actual location

, 2
thematic accuracy Answer: accuracy of attributes stored in a table,
ie. population. includes potential bias.
planimetric feature Answer: physical manifestations that can be
seen from above, in real life and on a map.
Cadastral Features Answer: politically/legally defined features, no
real manifestations.
statistical classificatiotn Answer: puts same number of features in
each class using standard deviation, good for income data.
MAUP Answer: Modifiable Areal Unit Problem. The same basic data
will map differently when aggregated in different ways
Two types of effects:
- Zonation: Major differences in result depending on how the study
area is divided up (i.e. neighbourhood/ward), even at the same scale
- Scale: Major analytical differences depending on the size of units
used (local variation missing from the big picture)
Solved through Normalization
projections distort Answer: shape, area, distance, direction
coordinate space Answer: an agreed upon range of coordinates
used to portray features
