lonlatapi

{lonlatapi} finds OA (Census output area) data from longitude and latitude data.

It's really slow because it downloads boundary data at every step. It would be a lot quicker if it used the local boundary data that a package like {geographr} provides. But this package would need to be written quite differently.

{lonlatapi} depends on boundr.

Installation

You can install the development version of lonlatapi like so:

devtools::install_github("francisbarton/lonlatapi")

Examples

library(lonlatapi)

find_oa(lon = -1.234, lat = 54.567)
get_full_oa_data(lon = -1.234, lat = 54.567)

oacd <- find_oa(lon = -1.234, lat = 54.567)
get_full_oa_data(oacd)

Further development

Currently lonlatapi only works for a single lonlat supplied. I would like to make it so it could handle a list of lonlats, and efficiently re-use any downloaded boundary data within that list.
