FAQ: What are the new map projections for ArcGIS 8.1 Service Pack 1?
What are the new map projections for ArcGIS 8.1 Service Pack 1?
The new map projections are:
· Craster Parabolic
· Flat Polar Quartic
· 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.
