This instance of the Seme4 Platform hosts a number of datasets released by Hampshire County Council under the Open Government Licence for public sector information.

During the Blue Light Camp 2014 we took a selection of raw datasets and utilising Seme4's technology stack converted them into Linked Data which is available from this domain. We also added datasets to geospatial indexes which allow you to make powerful geospatial queries over this data via simple RESTful requests (see below).

Finally, a simple visualisation allows you to view the various resources as overlays on a map.


  • Primary school catchment areas (example)
  • Secondary school catchment areas (example)
  • Street lights and (lit) bollards (example)


See also the full index of services.

Lookup services

Using the geospatial indexes, we can find things which contain or are near to a given location.

You can use the forms below to enter a postcode or latitude/longitude position, and find the appropriate school (based on catchment areas) or nearest street lights (erm...?)
