GISP Actual Questions and Correct Answers
Q1
Cartography
Answer: The art and techniques of making maps. Cartography requires the
identification of who, what, where, and how.
Q2
3 Ways to specify color
Answer: RGB: Red, green and blue CMYK: Cyan, magenta, yellow, black
Q3
HSV: Hue, saturation, value
Answer: HSV: Hue, saturation, value
Q4
RGB
Answer: Red, green and blue is the additive color system. The absence of each color
creates black and the max value of 255 of each color creates white. The combination
of 2 colors creates a subtractive color.
Q5
RGBA
Answer: The A is for "Alpha". This value indicates transparency. 0 is fully transparent.
255 if using 8-bit color, is fully opaque.
Q6
Opacity
Answer: Lacking transparency or translucence.
,Q7
CMYK
Answer: The subtractive color system creates colors with the bases: Cyan, magenta,
yellow and black. The absence of all bases is white light. Subtractive colors absorb
parts of the light spectrum leaving the rest of the spectrum behind. Mixing all
subtractive colors creates black.
Q8
HSV
Answer: Hue, saturation, value is another additive color system. Hue is the additive
color base determined by amounts of primary colors. Saturation is the intensity of the
color. Less
Q9
Feature Map
Answer: Show real world features represented by cartographic objects. Used for
navigation and reference maps. Also called reference maps.
Q10
Thematic Map
Answer: A map of a particular subject matter or theme. A thematic map usually
visualizes properties of geographic features that are not visible such as temperature,
language or population. It's best to use an equal area projection for a thematic map.
Equal area conic projections are used for the US, and equal area cylindrical projections
are used for the world.
Q11
Thematic Map Types
Answer: Choropleth Map Dasymetric Map
Q12
Choropleth Map
Answer: A thematic map that uses shading, colors, or patterns to show quantitative
data about geographical areas. Each color or pattern represents a range of values.
, Q13
Dasymetric Map
Answer: Ancillary information is used to model internal distribution of the
phenomenon. A dasymetric map is just a choropleth map where the areas have been
divided into more areas using another layer.
Q14
Isarithmic or Isopleth Maps
Answer: Maps with lines of equal value are drawn (contour lines) or ranges of similar
values are filled with similar colors or patterns. Represents a continuos surface.
Q15
Dot Density Map
Answer: Shows distribution of quantitative phenomena where values and locations are
known. Dots are placed where locations of variables are.
Q16
Multivariate Displays
Answer: More than 2 sets of data on a single map
Q17
Proportional Symbol
Answer: Size of the symbol corresponds to the magnitude of the mapped feature
Q18
Graduated symbol
Answer: The size of the symbol represents a range of values
Q19
Divergent Color Ramp
Answer: Shows when values are above or below a central value. Example: elevation
above or below sea level.
