Georeferencing -
CORRECT ANSWER: Associating a map (such as a pdf without spatial
information) or image (such as an aerial image without spatial
information) with spatial locations.
QUESTION: Control Points -
CORRECT ANSWER: Consisting of multiple points, points come in
pairs that match the spatial location with a point on an unreferenced
image or map.
QUESTION: Spatial Reference System (SRS) or Coordinate Reference
System (CRS) -
,CORRECT ANSWER: A coordinate-based local, regional or global
system used to locate geographical entities.
QUESTION: International Terrestrial Reference System (ITRS) -
CORRECT ANSWER: It's a three-dimensional coordinate system with
a well defined origin (the center of mass of the Earth) and three
orthogonal coordinate axes (X, Y, Z).

CORRECT ANSWER: Transforming coordinates from a curved earth
to a flat map.
