It is a three-dimensional coordinate system with a
International Terrestrial
well-defined origin (the center of mass of the Earth)
Reference System (ITRS)
and three orthogonal coordinate axes (X,Y,Z)
transforming coordinates from a curved earth to a flat
Map projection
map
model of the earth as a spheroid (2 components,
reference ellipsoid and a set of survey points both the
Horizontal datum
shape of the spheroid and its position relative to the
earth)
reference point for elevations of surfaces and features
Vertical datum on the Earth - could be based on tidal, seas levels,
gravimetric, based on a geoid
NAVD88 gravity based geodetic datum in North America
set of control points whose geometric relationships
Geodetic datum
are known, either through measurement or calculation
World Geodetic System - reference coordinate
WGS 84
system used by the Global Positioning System (GPS)
spatial reference system id numbers, including EPSG
SRID integer codes defined by the International Association of Oil
and Gas Producers
4 distortions Distance - Direction - Shape - Area
Preserves shape and direction, area gets distorted -
Mercator Projection
projecting earth onto a cylinder tangent to a meridian
planar (tangent) - used for air route distances -
distances measured from the center are true -
Azimuthal Equidistant
distortion of other properties increases away from the
center point
preserves area, shape and distance gets distorted
near the upper and lower regions of the map -
Cylindrical equal-area
straight meridians and parallels - meridians are
projections
equally spaced and the parallels are unequally
spaced
