There is no direct link other than I created both of them. The 180m
DEM was generated from an older and more error-prone version of the
base data, utilising different software, while I was working for a
different organization, and using a *much* slower computer! :)
The 180m DEM should be considered an inferior product and is not
recommended for use unless you need a DEM at that pixel size and
lack the facilities to resample the 90m DEM to ~200 meters.
I guess I should add all that to the 180m download page. :)
> I have described your license as Public Domain - is that correct?
Essentially. It is public domain with a non-binding entreaty to be
courteous and responsible in crediting the source:
"License Terms
The DEMs are free, in both the sense of cost and of liberty.
You are free to use these DEMs in any way you see fit including
commercial endeavours. It would be courteous to inform us what
you are doing with them and to credit the Yukon Renewable
Resources Geographic Information System or Yukon RRGIS where
applicable."

Thanks for the added emphasis Jan.
Cheers and a Happy New Year to All!
