What are the new map projections for ArcGIS 8.1 Service Pack 1?

Last Published: April 25, 2020


The new map projections are:

· Aitoff
· Craster Parabolic
· Flat Polar Quartic
· Gnomonic
· Hammer-Aitoff
· Orthographic
· Times
· Vertical Near-side Perspective
· Winkel Tripel

Supporting PRJ files are available in the Polar and World folders under Projected Coordinate Systems folder.

Vertical Near-side Perspective is only supported for spheres. If your data does not completely close at the edge of the projection, check that the geographic coordinate system is based on a sphere.

The Winkel Tripel inverse is not working correctly. See Related Information.
