Hi Bill, super interesting work you've done here. Would you be interested in adding a link to this site on the gallery.openlayers.org page? Or can you think of another, better way to share this information with people?
I have thought it over a couple of times and I can't seem to come up with any good place to plug this info in... yet I feel it might be of big help to someone else down the line.... I guess the best I can do is suggest making a wiki tutorial for it. cheers! e On Sat, Aug 23, 2008 at 6:33 PM, Bill Thoen <[EMAIL PROTECTED]> wrote: > A while ago I asked a question here about how I could simulate pipeline > flow in a live, animated way.
