Rubbersheeting problems

Dear all,

It seems that Rubbersheeting (maybe the most powerful option out of Raster
Design weaponry) is not working correct when given a file of 1 or 2 Mbs and
more than 20 control points (should be polynomial equiation to the 5th or
6th degree). Either it doesn't work (draws circles and ellipses), or just
says that there's "not enogh virtual memory" to perform such operation.

How to overcome this "memory" problem? Can't RD just flush the data onto the
disk? Is out there anybody who tried to use DLLs and OCXs comming out with
the old Imaging software? I need it for raster callibration purposes with 60
or even 100 control points.

Regards,

Raster Design has a limit of 2GB in it's swap file.
Depending on the amount of imagery you have loaded, the size of the ultimate
rubbersheeted image, and the free space on the drive that is being swapped
to, you may be hitting this boundary,

Alos, 60 to 100 points is a large number for a polynomial solution. Raster
Design 3 and up can do a "triangular" rubbersheet that will accept the
number of points you are looking for and likely give much better results.

Thanks, Jeff. Such large number of control points is simply a result of
"very precise" rubbersheeting that goes down each quadrangle "tick mark"
appearing on geodetic plans and maps. Alas, I'm using Autodesk Map 5/6 and
the old CAD Overlay 2002, that doesn't come with Triangular function
implemented. Now I have to think of some "new mathematics" that will try to
rubbersheet every quadrangle and, finally, "glue" them together as SoftDesk
Imaging did.
