Bezitopo consists of several programs: * Bezitest is the test program. * Bezitopo is a command-line program, which I use mainly to check closure and to convert pointlists from PENZD to PNEZD. Eventually it will be renamed bezitopo-cli and what is now ViewTIN will take over. * Clotilde computes approximations to Euler spiralarcs. * Convertgeoid converts geoid files from one format to another, resamples them, and makes excerpts of them. * Pangeoid does nothing yet. It's going to be a GUI version of Convertgeoid. * SiteCheck reads a TIN file and is supposed to let you walk around with a GPS system and check it for accuracy, but I have no interface to a system yet. * Transmer computes coefficients for transverse Mercator projections. * ViewTIN reads a list of points, breaklines, and criteria for including or excluding points, makes a TIN, and draws contours. Once it can also draw line segments and has the drawing object list and layers working, I'll rename it to Bezitopo. It's intended to be a CAD program for land surveying (as distinct from a general-purpose CAD program with surveying tacked on), but it isn't there yet.
You can download it from http://bezitopo.org/bezitopo-0.1.5.html . If you'd like to contribute, please see http://bezitopo.org/developers.html and join the mailing list. You don't have to be a coder. Some tasks you could do are: * Draw the three foot icons (PerfectTIN needs them too) * Translate strings * Enter map projections (SPC and whatever is used in other countries) * Find samples and specifications of geoid file formats * Find information about the offsets of ellipsoids.
