This is a true Delaunay, but which necessarily introduces new Steiner points along edges. There is also a notion of a constrained Delaunay, which isn't true Delaunay but which doesn't split edges. JTS does not have code to compute this.Dr JTShttps://www.blogger.com/profile/02383381220154739793noreply@blogger.comtag:blogger.com,1999:blog-2420860529344694449.post-50778384751200740042011-01-10T08:33:10.218-08:002011-01-10T08:33:10.218-08:00Hi Martin,

It is easy to use and very quick. <br /><br />However, I did not find how to compute a conforming Delaunay triangulation without creation of new points on the constraint edges. I know in this case the triangulation is no more a 'Delaunay' triangulation, but is it possible to get it?ouiouihttps://www.blogger.com/profile/16444699787688927403noreply@blogger.comtag:blogger.com,1999:blog-2420860529344694449.post-58856910394674944592010-01-07T14:57:28.549-08:002010-01-07T14:57:28.549-08:00Hello Martin,

My interest is in nterpolating surface with a VERY large number of data points, using the Delaunay triangulation.<br /><br />Thanks,<br /><br />Alex Molochnikov<br />Kelman Technologies Inc.Alexanderhttps://www.blogger.com/profile/02278314022763541741noreply@blogger.comtag:blogger.com,1999:blog-2420860529344694449.post-76190791870085591462009-08-12T21:29:36.747-07:002009-08-12T21:29:36.747-07:00Julia,

It is being used in production for computing watersheds for the BC stream network, and has worked well for that application. As long as there was a suitable driver to read the USGS data, I expect it would be able to run on it as well.<br /><br />You're right about there being a lack of information & code available, though. As you know, it takes a bit of effort to package up an application along with documentation to make it usable by a wider audience. Unfortunately the client sort of lost interest in doing this, and we haven't devoted the time to doing so up til now. <br /><br />I can provide the presentation easily - in fact, I'll make it available online. The source could be available too - with the proviso that it will probably need some work to make the inputs & outputs more generally usable. What I'd like to do is to provide WaterBuG as a JEQL extension - that will make it much more easily configurable for inputs, outputs and parameters.<br /><br />Feel free to contact me directly for more info.Dr JTShttps://www.blogger.com/profile/02383381220154739793noreply@blogger.comtag:blogger.com,1999:blog-2420860529344694449.post-28922541010184413072009-08-12T20:30:53.020-07:002009-08-12T20:30:53.020-07:00Hi Martin

Never was able to find a copy of your presentation from FOSS4G 07 or GeoTec07 anywhere online - just a couple of "teaser mentions" here & there. Is WaterBuG still alive ? If so, any information available about it? Would it be possible to use it on USGS NHD format stream network data ? <br /><br />Thanks,<br /><br />Juliajlhgishttps://www.blogger.com/profile/08159627766378190128noreply@blogger.comtag:blogger.com,1999:blog-2420860529344694449.post-11343957736277113892009-05-17T02:09:00.000-07:002009-05-17T02:09:00.000-07:00Hello.

But research will pick it up for sure.mentaerhttps://www.blogger.com/profile/06337822862621103715noreply@blogger.com
