I can suggest to use collective.geo to manage georeferenced data and develop a subscriber for IGeoreferencedEvent (you can find it in collective.geo.geographer package) to store this data in external 'catalog' that provides a simple spatial index as mongodb or solr for instance. You also have to develop a map widget (see. collective.geo.mapwidget) to query the external catalog. Somebody have developed a spatial index for Zcatalog (https://svn.plone.org/svn/collective/collective.geo.index) but I never tried it.
