Hello Rob, Sorry for the late reply on this. Basically how it works is:
- the shapefile was converted to Postgres SQL using shp2pgsql; - the data was imported into a PostGIS database; - some custom code (actually same underlying code as Freemap) was written to fetch data as GeoJSON from the database by bounding box; - Leaflet was used to produce the overlay; this is quite easy as Leaflet automatically handles GeoJSON. I'll try and write it up as a blog post. Some (old) code for doing this is on the Freemap github site; I'll try and update it in the next few days.

Is there any guides for how to do something similar? I was trying to visualise the Natural England data using Leaflet but failed miserably as the shapefile is too big. Your website appears to load just the bit needed. Would I be able to use some of your code? Cheers, RobJN p.s I'm not hugely tech savy, but with a simple set of steps (e.g. Load data in x, tweak code where there are references to y&z, etc) should be enough to get me started as I can research the details on google.
