[mapserver-users] projection question

[Michael Scharber]

Hi there,

Does anyone know if it's possible to get mapserv to use new lat_0 and/or
lon_0 parameters for a projection defined in a PROJECTION section of a
.map file, on subsequent user requests?  I'm using the following initial
parameters with mapserver 3.5 (cvs from 2001 08 01) and proj 4.4.3:

PROJECTION
  "proj=ortho"
  "lat_0=0"
  "lon_0=-110"
END

How can each call to mapserv re-center the next image, in the given
projection, at the location clicked by the user?

Thanks in advance.

Michael
