Re: [udig-users] Georeferencing

[andrea antonello <andrea.antonello@xxxxxxxxx>]

Hi Mathieu,
sorry for jumping in late, been abroad yesterday.

As Ugo states, this is what you are searching for:
http://svn.refractions.net/udig/udig/community/net.refractions.udig.imagegeoreferencing
I have looked with interest at the time it was developed (by Graham I
think) but then no feedback ever came back to the list. I don't know
if it even works.
If you try it out, please give us some feedback on that.

You are not the first one to say that :)

Given the fact that from your first request JGrass is not what you
need, I will anyway answer the following :)

We have documentation for importing those data on the JGrass website:

Cool, that is what it is for.

Hei, thanks for that, I will have to investigate. Didn't know that.
