Projection and Location
Example
of How the Albers Projection is Derived:
Projection Information for
the Project Area:
All coverages and images were
projected into Albers Equal Area (This conic projection uses two standard
parallels to reduce distortion. Although neither shape nor linear scale are
truly correct.)
First, I re-projected one coverage into the desired Albers Equal Area
projection using ArcToolbox and saved the (output) projection file. This file was then used for all subsequent
coverage re-projections. The following
is the projection file (.prj) created in Toolbox:
(*NOTE* is was not necessary to have the input
projection definition in the projection file (.prj), as each coverage was in
the same initial projection.)
