GIS final exam Questions and
Answers 100% Pass
What does GIS stand for? - ✔✔Geographic information system
Given a good definition for GIS, list the four components and put a star next to the most
important one - ✔✔software, hardware, spatial data, people*
List four things GIS can do - ✔✔enter data, store/display data, analyze data,
manipulate data
Name the two general types/kind of data - ✔✔attribute and spatial
example of spatial data - ✔✔spaulding hall, room 217, UNH, Durham NH
example of attribute data - ✔✔there are 30 cats in a veternarian clinic. 15 of the cats are
black
spatial data - ✔✔geometric, coordinates, location
attribute - ✔✔non-spatial characteristics
nominal (descriptive), ordinal (range), interval/ratio (order and distance)

, uses lines, points(x,y) and polygons to make up spatial features on a map. The topology
is CREATED using attribute tables and features. More complex but more visually
pleasing - ✔✔Vector format data
topology - ✔✔what is next to what and what is connected to what. the spatial
relationship between cartographic features. defines adjacency and connectivity.
equal grid cells or pixels. larger cells show poorer spatial resolution. easier to
manipulate but uses A LOT of storage space - ✔✔raster format data
topology in raster - ✔✔topology in raster data is IMPLICIT through the cartesian
coordinate system. you know that (2,1) is connected to (2,2) because it is implied
what is the purpose of database structures - ✔✔to manipulate, query, analyze, and
organize tabular data
what is the main difference between network and hierarchal database structures -
✔✔network database is more flexible due to having multiple parents and multiple
children all connected. however, it shares data and can be complex. hierarchal is harder
to manipulate having a 1:1 parent children ratio, it is very defined.
what is a relational database - ✔✔data and information is formally structured through a
set of connected tables. MOST COMMONLY USED IN GIS
