Rotated Orthographic View?

[Ed McNierney]

Your description is a little confusing.  Why do you need to rotate it
into the "right position"?  What's wrong with the original position?  If
it's "wrong", are you simply trying to generate a different projection
than the orthographic?

MapServer should be able to project your original shapefiles from any
projection to your desired output.  I don't see any reason why you'd
need to modify the shapefiles from the original lat/lon distribution
format.

You simply need to be able to accurately describe the desired output
projection.  Please give us the complete details of the orthographic
projection you're choosing in ArcMap.

Subject: [UMN_MAPSERVER-USERS] Rotated Orthographic View?

I have a US lower 48 state/county map view in ESRI ArcMap that I have
exported shapefiles out of, and use them in MapServer/PerlMapScript to
generate maps for the Web.  When using a Mercator projection, everything
works fine, but now I need to use an orthographic projection.  When
using ortho in ArcMap, the map appears rotated, but I can use ArcMap's
Rotate Data Frame tool to get it in the right position.  Exporting the
rotated map to a shapefile and processing it in MapServer/PerlMapScript
however doesn't maintain the corrected rotation.

How can I have MapServer/PerlMapScript rotate the map prior to
generating an image from it?

Thanks!
