topographical mapping tool

[robo100]

Has anybody ran across a topographical mapping tool that will allow VB programmers to make mapping applications? I ran across one from thinkgeo.com that looks nice but it's not a topographical type map, just flat 2D (and it's $5,000). I have looked around a little but have not found one that is .NET compatiable.

If you can find a COM component you can still use it in .NET apps, although it would obvioulsy be nicer to find a managed component.
