[ckan-dev] GIS dataset import

Fri Jan 17 09:01:15 UTC 2014

Hi Phillippe,

This is indeed awesome. We are currently actively working on a big new
feature for improving resource views, to allow users to customize them
and crate dashboards with them ([1], to go into 2.3), and geo previews
is something that has been requested a lot, so the timing is great.

I'm keen on moving the geospatial previews to a separate ckanext at
some point so it's easier to contribute to and not so tied in to the
rest of ckanext-spatial, which is only related conceptually but not in
code. This should in no way affect your work!
