Doug --

For an avocational interest in ancient Greek history, I recently purchased a mapping program from a group down under. It's available as shareware, but much less expensive than commercial packages, and I suspect that they would do volume discounting (a shareware author's dream!). Nice system developed in Delphi.

There's no real programming capability, per se. However, the ability to create layers of maps and selectively show them adds an interactive ability. I don't think it exposes an OLE interface. You'd work with it as a separate application, and generate data files for it to use.

If you're interested, I can give you contact info (that's all on my home system).
