Convert ONS Shapefiles to GeoJSON

This gist describes how to create GeoJSON polygons from UK statistical boundaries for use in choropleths.

  1. Download the boundaries you're interested in from the ONS's Open Geography Portal:

    wget https://geoportal.statistics.gov.uk/Docs/Boundaries/Clinical_commissioning_groups_\(Eng\)_Apr_2013_Boundaries_\(Generalised_Clipped\).zip -O ccg-2013.zip
unzip ccg-2013.zip -d shapes

  2. Re-project this from UK Grid Reference Eastings and Northings into Latitude and Longitude coordinates (i.e. EPSG:4326 aka WGS 84). You can use GDAL to do this:
