Which of the following topological relationships describe the arc-node relationship in the
coverage model?
Connectivity
Which of the following is true about the vector data model?
-The model uses points, lines, and polygons to represent simple spatial features.
-The representation of spatial features using the vector data model depends on map
scale.
-The model uses x-, y-coordinates to store the geometry of spatial features.
Select the following statements that are true about a GIS database:
-Real world data is represented as separate thematic layers
-Data from different thematic layers are combined through analysis
-Thematic layers organize spatial and attribute data
Multipart features are used to represent multiple geographic objects that represent parts
of the same entity
True
A geological map showing bore holes, faults, and rock outcrops that emit radon (in that
order) could be captured into the GIS as:
Points, lines, and areas.
Topological data layers often ease data processing and maintain spatial integrity, at the
cost of more complex data structures.
True

height of the tallest tree in a city?
Interval/ratio
What type of attribute is human population (the number of people in a state) in a data
layer for the U.S.?
Interval/ratio
What type of attribute is political party of the current governor for a states data layer for
the U.S.?
Nominal
Which of the following is true about a line feature?
, - A line feature is made of line segments (arcs).
- A line connects two end points (nodes).
- The shape of a line is defined by arcs connected by vertices.
Choose all of the statements that are true about attribute tables:
-An attribute table is associated with each thematic layer in a vector data model.
-A single row in the attribute table corresponds to each feature
-Each feature is given a unique numeric identifier within the attribute table.
A line digitized in a vector GIS is considered a ___ object.

You have a spatial data layer for country life expectancy rates, with boundaries and an
attribute table. What type of data (nominal, ordinal, interval/ratio) are rankings for life
expectancy contained in the data table?
Ordinal
In the vector data model, starting and ending points of a line are referred to as nodes,
with vertices representing the intermediate X,Y coordinates in a linear feature.
True
Topology is:
The spatial relationship between features on a map
You have a spatial data layer for Minnesota school districts, with boundaries and an
attribute table. What type of data (nominal, ordinal, interval/ratio) are rankings for
graduation rate, contained in the data table?
Ordinal
The cell coordinate of a raster cell is usually defined as a point at the center of the cell.
True
If a raster has the cell dimension of 30 meters, then the area of a cell in this raster
measures:
