pMap 1.1

Welcome to pMap v1.1. It’s a minor update on 1.0 which makes use of slightly neater scraping which is faster to relay; allows toggling of wards; allows re-centering of the map. It’s currently working on the previous 7 days’ planning applications registered. You can see the source code below, or fork it.

pMap


TODO
Still working on geocoding locations without a postcode. Allowing custom date ranges to be explored, and conservation areas to be observed are still on the list. Google map clustering (by ward/conservation area) will be investigated, as well as bringing in more of the originally scraped information, such as application progress stage.
