Re: technique for changing map projections within a display??

Hi Stuart-

Hi Don, thanks for the pointer. Yes, I see that that class uses the same approach that I was using, keeping displayrealtype names unique using a counter. Obviously (??) any existing displayrealtypes are just discarded when the scalar maps are removed. Your class really does have much that i need, I'll consider subclassing it.

There are existing subclasses already (MapProjectionDisplayJ3D,
MapProjectionDisplayJ2D) so I'm not sure you need to create your own.

On a related note, is there any form of 'tutorial' or docs on IDV for developers? The user's guide seems more of a manual for the IDV app itself. The class library looks very powerful, it might just be that people don't know what there is available and/or where to look.

Unfortunately, no.  It's on the list of things to do. ;-)
Your best be now would be to join and post to
idvdevelopers@xxxxxxxxxxxxxxxx and we can answer specific questions
there.
