[GRASS-user] Re: TIN (Linear interpolation) from points

[Daniel Lee]

Hi Danny,

Theoretically that should be fine. I doubt that your points are less than a
meter apart. To tell the truth, I'd need to take a look at the data a bit
more to be able to say much more about it. Your command looks fine to me.
You could also try expanding the region by a hundred meters or so, just to
take a look at whether the points perhaps aren't being converted because
they're right on the edge of your raster. I honestly don't think that'd do
it, but it would be an easy experiment that I would try.

Daniel
