●● Continuous data
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)
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
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
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?
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
Answer: A system that defines locations on a flat map based on x,y
coordinates
●● Projection types
Answer: cylindrical, conic, azimuthal (planar)
●● Cylindrical projection
, 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
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
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
Answer: Cylindrical projection
●● Most suitable projection for map areas that extend east-west
Answer: Conic projection
●● Most suitable projection for map areas that have equal extent in all
directions
Answer: Azimuthal/planar projection
●● Map properties
