Projection refers to a projected coordinate system based on a map projection such as transverse Mercator, Albers equal area, or Robinson, all of which (along with many other map projection models) provide various mechanisms to project maps of the earth's spherical surface onto a two-dimensional Cartesian coordinate plane. Projected coordinate systems are sometimes referred to as map projections.

- on the fly reprojection
On-the-fly reprojection is a process that takes data stored in latitude and longitude format (unprojected data) and transforms its visual representation to match other projected datasets. - spatial reference
A spatial reference is a set of parameters, typically defined by a WKID, that define the coordinate system and spatial properties for geographic data. Applications use a spatial reference to correctly display the position of geographic data in a map or scene.
