Questions and CORRECT Answers
Discrete data - CORRECT ANSWER - Represents real-world features that have well
defined boundaries. A discrete feature is distinct from the other features around it.
Example: A river is a discrete feature: there is a distinct place where you stop being dry and
begin getting wet.
Continuous data - CORRECT ANSWER - Represents real-world features that do not have
well-defined boundaries.
Examples: Elevation, temperature, rainfall.
There are no distinct places where the phenomena simply stop; values may change abruptly, but
the phenomena continue to be measured.
Hint: if it makes sense to take an average of the values, it is likely continuous data
Geographic Coordinate System (GCS) - CORRECT ANSWER - Uses a spherical model to
identify points or areas on the surface of the earth. Each coordinate system is commonly
illustrated with a network of intersecting lines of latitude and longitude called a graticule
Graticule - CORRECT ANSWER - a network of intersecting lines representing meridians
(longitude) and parallels (latitude), on which a map or plan can be represented
Four components of a coordinate system - CORRECT ANSWER - Angular units of
measure
Prime meridian: Zero value for longitude
Spheroid: Mathematical model that estimates the size and shape of the Earth
Datum: A frame of reference for measuring locations on the surface of the Earth. It defines the
origin and orientation of latitude and longitude lines.
, Why are there multiple spheroids in use for geographic coordinate systems? - CORRECT
ANSWER - The Earth's surface is not symmetrical, causing the semi major and semi
minor axes that work for one geographic region to not work for another region
Projected coordinate system - CORRECT ANSWER - A system that defines locations on a
flat map based on x,y coordinates
Projection types - CORRECT ANSWER - cylindrical, conic, azimuthal (planar)
Cylindrical projection - CORRECT ANSWER - a map created by projecting Earth's image
onto a cylinder. Meridians and parallels intersect at right angles, as they do on the globe
Conic projection - CORRECT ANSWER - Created by setting a cone over a globe and
projecting light from the center of the globe onto the cone. In general, distortion increases north
and south of the standard parallel
Azimuthal/planar projection - CORRECT ANSWER - When projected on either of the
poles, longitude lines radiate outward from the pole at their true angle. Latitude lines appear as a
series of concentric circles. Most often used to map the polar regions.
Most suitable projection for map areas that extend north-south - CORRECT ANSWER -
Cylindrical projection
Most suitable projection for map areas that extend east-west - CORRECT ANSWER -
Conic projection
Most suitable projection for map areas that have equal extent in all directions - CORRECT
ANSWER - Azimuthal/planar projection
Map properties - CORRECT ANSWER - Shape, area, distance, direction
