[talk-au] Proposed Data import - Queensland, Australia: Peaks and Mountains

[Ian Sergeant]

Hi,

The overall import strategy looks good to me.

I can, however, personally see absolutely no point in adding SRTM data
to mountain elevations.  None will be accurate.  None will be official
mountain heights. You could equally well add ele data to every single
node in OSM using SRTM.

If there is an official survey height that we have access to, we
should add that.  Or even an actual measured height.

Ian.
