[Qgis-user] Re: Azimuth and Distance Plugin (was Re: your old qgis plugins)

[Maurício de Paulo]

Hi Darren,
Could you give me an example of the precision problem (azimuths and
distances).
Ah, the Zenith is a vertical angle measured from the terrain's normal vector
on the point i'm measuring.
In short, it's the vertical angle measured on old optical equipment. It's
there just to be a way of drawing 3D geometries (even though it's not really
available yet). At 90 degrees the line is drew on the horizontal plane.
Ok, I can see people have interests on different ways of input coordinates.
They're not as important as the bugs reported, but I'll keep an eye on these
sugestions. Maybe inserting a new box to let the user choose from many input
types. For now, let's work only with standard azimuth and let the user do
the conversions. At least until the plugin is working properly so I can
focus on new features.
One thing: The snap is already implemented. It worked fine here. I'm going
to try to reproduce the bug you reported but I'd really apreciate the data
you used as input. Is it possible?
Thanks for the inputs.
Mauricio de Paulo
