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

N N N N N N N N N N N N
scale between one or two points to every other point on the map, or along every meridian. Distance
N N N N N N N N N N N N N N N N N N
is correct, but distortion is constant
N N N N N N
An equidistant projection preserves and distorts which properties? - ANS >> Preserves direction from
N N N N N N N N N N N N N
one or two points to every other pointPreserves direction from one or two points to every other
N N N N N N N N N N N N N N N N N
point

Any distance or direction measured from the center of the map will be accurate, but any distance or
N N N N N N N N N N N N N N N N N
direction measured from any other point will be inaccurate
N N N N N N N N N
Any distance or direction measured from the center of the map will be accurate, but any distance or

N N N N N N N N N
Compromise projection - ANS >> A projection that does not have equal area, conformal, or
N N N N N N N N N N N N N N
equidistant characteristics, but rather seeks to minimize and balance distortion overall.
N N N N N N N N N N N
Geodatabase - ANS >> A database or file structure used primarily to store, query, and manipulate
