Hello Sean,
The Chart for .NET Editions Comparison List is available on the website and in the help documentation. If you were in conversation with someone at Nevron about the editions, you should have been informed that the Triangulated Surface series is part of the Enterprise edition.

Anyways, you can contact our Sales Team regarding the upgrade from Professional to Enterprise edition. They will surely provide a cost effective option for you.

Best Regards,
Nevron Support Team

I have a dilemma where I spent a ton of time building out an app that plots a surface map using a data file containing latitude, longitude, and elevation points. The data is acquired by radio controlled boat that performs a grid pattern on a reservoir. 

After some discussions with the folks in this forum, it was suggested that I use the triangulation interface. I implemented the triangulation interface and was able to plot the surface map.I had a conversation with the folks at Nevron about purchasing the Nevron Chart for .Net package and it was apparent at the time that the professional edition would be the right fit. Wel I purchased the package a few days ago and discovered that the triangulation feature is not a part of the professional edition.

I only need the surface map feature. Is there a way to plot the data without the use of triangulation. I suppose the list is ordered if the boat is running a grid pattern. Is there a way that I can convert my latitude / longitude to an ordered list? Maybe there is a library out there that does this. I have a client that is not happy with the fact that he might have to pay another $1000 just to use the triangulation feature. Please help.
