[Talk-GB] OpenHants - doing something with the Hants CC data in the meantime

[Nick Whitelegg]

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.

Nick

Fantastic use of the data Nick!

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.
