RE: [OSGeo-Discuss] RE: Open source TIN code?
Yeah, I have anecdotal evidence Isenburg gave the OK (Hobu noted it on the liblas list), but he didn't specify exactly for *what* he was okay with from the tools collection which makes me nervous. If he were to say all of it, then we're all set (I just care about the TINner inside lasview). Sometimes it's a pain when you try to play by the rules :-( -mpg -Original Message- From: discuss-boun...@lists.osgeo.org [mailto:discuss-boun...@lists.osgeo.org] On Behalf Of Mateusz Loskot Sent: Monday, March 23, 2009 4:55 PM To: OSGeo Discussions Subject: Re: [OSGeo-Discuss] RE: Open source TIN code?

Again this is GPL, not BSD, but GRASS GIS has TIN support: http://grass.osgeo.org/grass64/manuals/html64_user/v.delaunay.html --Wolf On 02.03.2009 20:34, Traian Stanev wrote: Not sure about the BSD licensing part, but here are some cool TIN triangulators which are open source.
