A quick write-up of the geo-open space session held at Plone Conference
Giorgio Borelli presented collective.geo.* the collection of libraries to integrate geo-information in any Plone content-types.
They use zgeo.* packages as base-products, so collective.geo.* are mainly plone intregation layers.
We have also talked about other Plone products that provide map integration like Products.maps, and when asked about that, Giorgio has told us that he didn't want to stick always to Google Maps, so he developed this product that uses OpenLayers, and also that Products.maps doesn't support lines or polygons.
If I missed something, please post a comment! Photos tomorrow or on sunday, the USB cable is in my hotel room :(
