Hello!

I have several curving lines which I would like to "buffer" with radiating lines instead of the usual polygon; as illustrated in the attached, finely drawn, picture ;) Is this possible? I use ArcGIS and Manifold - any extensions that could do this?

Thank you!

Is it just going to be a visual trick? No analysis with that buffer? In that case, you could try setting a really big line width on a dashed line with a really short dash and a really long gap.

Unfortunately It's going to invole an analysis, so they have to be real lines. Otherwise a very interesting idea :D

Search the forum for a thread on riparian zone buffering, I seem to remember a discussion not too far back involving just this sort of analysis. I believe Gretchen Peterson was the post author.

Sounds like you have a river thalweg and want to add lines perpendicular to it that have a specified length. I've done this using tools from www.ian-ko.com/ - Ian builds tools for ArcView (cost is about $250). Otherwise, you might have to scour the ESRI site for VBA code.

This can be done relatively easily with Manifold spatial SQL. I'm pretty sure there was a threat about this sort of thing on Georeference.org not too long ago.

I haven't had time to try out any of the suggestions yet, but I am sure some of them will work - thanks!
