I'm trying to do some data analysis on crime rates within my local constituency. I'm using the UK Police API to get the data but currently, I have to manually define the boundary using longitude and latitude coordinates defining a polynomial.

Is there any way to download the outline of UK constituencies as longitude and latitude coordinates?

The ONS has what looks like the data you're looking for - digital vector boundaries for Westminster Parliamentary Constituencies in the UK, as at 31 December 2017.

  • Is there anyway to compress the geospatial data as the API gives a URI too long error?
