comment Are there any open source network analysis tools?
Once this is closed, it would be helpful to combine the other two under a useful title. Alternatives to pgRouting has better answers, but its title is less informative.

Oh, you're right. My cursory glance for questions didn't turn those up. Let's vote to close before more answers show up.

comment Given a terrain, how to draw the stream flow path?
Okay. When you said "I am less clear on how to execute this", I assumed you wanted practical advice on how to do this. Presumably the workflow used by these software packages could provide a guide to the overall structure of your algorithm. From there I suggest you consult the academic literature about specifics. For example, Tarboton, 1997 was referenced several times in my search for flow direction algorithms.

It's be nice to have a more specific description of what your raster now looks like and what you'd like it to look like. What specifically bothers you about it? The pixelated edges?

Well, this seems to be the procedure used by most GIS packages. TerraFlow is an open source option, but I have never used it. What are you planning on using to handle the TIN?

Do you want to interpolate between the points or only represent the points you have?

What happens if you open a form, rather than a combo box? Or you could just change the HintText to your message.
