I'd like to find some people to contribute to Bezitopo or PerfectTIN. They are in the initial stages of incubation. They're both on my GitHub site, https:// github.com/phma/. Bezitopo also has a website at http:// bezitopo.org.
For Bezitopo, I'd like to define an internal (and maybe an external) representation of raw data files for both total stations and GPS systems. The input for least-squares adjustment will be in this format; I'll use a survey I've done as test data. Anyone interested in designing the data structure, please join the Bezitopo mailing list. If you can enter instances of projections (Lambert conformal conic and Gauss- Krüger transverse Mercator), that would help the program be usable in more locations. Also, if you know benchmarks in the Alaska panhandle or in Switzerland, that would help me make sure that oblique Mercator is correct. See testprojection() in bezitest.cpp for how I used Oakland and BV067202 as test data for conformal conic and transverse Mercator, respectively. Also, any ellipsoids that Bezitopo doesn't already have, to go with the projections, would be a help. Both programs need button icons drawn for the different feet. They have icons, but they're all the same, so the only way to see which foot you've selected is the tool tip. Even if you just want to understand the code, to increase the bus number, I'd appreciate that. Some of the methods have quite high McCabe numbers, and the quarter function which I'm writing (I still have to make it lock the TIN) is pretty complicated.
