I'm currently working on a python plugin for QGIS which deploys points
along lines on a given distance basis. The lines, say transects, are
created placing an initial point and then providing a bearing for the
line. Then, n stations/smapling points are deployed in its place.
I'm using Vincenty's Formula to get the coordinates for the points. So
far, I've found an python implementation for this, but I haven't been
able to know under which license is released the code, as far as I have
found the code in a forum
but the link provided in the message for the original code can't be
As far as I know, in QGIS API there is no direct Vincenty's formula to
compute in this way (point, azimuth/bearing + distance to destiny), and
I want to make the plugin dependence-free as possible, so my questions are:
1) Do you know if, in QGIS API, is there and usable implementation of
Vincenty's direct formula?
2) Is it fair to copy the code posted in the forum as is? (auto-answer:
I don't think so....)
3) In this case, how should it be credited in my code?
4) Should be better to reimplement it in a class apart and release it
under GPL3? is this possible?
By the way, the plugin name will be Transectizer... any better ideas?
