Subject [jira] [Created] (SIS-213) Lambert Conic Near-Conformal (EPSG:9817)
Date Fri, 10 Jul 2015 11:31:05 GMT
Martin Desruisseaux created SIS-213:

             Summary: Lambert Conic Near-Conformal (EPSG:9817)
                 Key: SIS-213
             Project: Spatial Information Systems
          Issue Type: Sub-task
          Components: Referencing
            Reporter: Martin Desruisseaux
            Priority: Minor

Quoting from § from _Geomatics Guidance Note number 7, part 2 – April 2015_:

The Lambert Conformal Conic with one standard parallel formulas, as published by the Army
Map Service, are still in use in several countries. The AMS uses series expansion formulas
for ease of computation, as was normal before the electronic computer made such approximate
methods unnecessary.

This is a projection used mostly for legacy data.
