[ckan-discuss] About Geospatial Features (and DataStore): a question from a CKAN newbie

Thu Jun 28 15:57:42 BST 2012

Hi Luca,

The ability to plot geographic locations from a datasets (like on this
case [1]) is powered by the Recline Javascript library [2], and it is
completely independent from ckanext-spatial (which is more focused on
providing spatial support for the datasets metadata, eg extent of the
dataset). If you are using the datastore, you will be automatically
able to preview csv based datasets. See the documentation for more
details [3], and make sure you are using the ckanext-datastorer
extension to automatically push new datasets to the datastore.

Hope this helps,

Adrià
