In francisbarton/jogger: Retrieve Area Boundaries and Data from the ONS Open Geography Portal

jogger

This package is now superseded by my boundr package, which avoids lots of the bad design decisions in jogger. Please use that instead!

Retrieve area boundaries and data from the ONS Open Geography Portal

The main function of this package is to download area lookups and boundaries (in GeoJSON format) using the ONS Open Geography API, for all sub-areas - at a specified level - within a specified area. The main script will return a data frame with the sub-area geometry column, as an sf object ready to be visualised as a map. It’s initially just for areas within England and Wales, with a hope to add Scottish geographies at a later date. And currently just for the following area levels: LSOA, MSOA, Ward, LAD/LTLA, UTLA/CTY, CAUTH, RGN [subject to change]
