In stupidpupil/twRch: twRch

A hacked together toy project to make some UK geography reference data, mostly from the ONS, easily queryable from R.

Uses fst for fast reads of data.

There are probably serious issues with respecting hierarchies correctly.

Features and Antifeatures

• Local postcode lookup (excluding Northern Ireland)
• Includes boundaries for Countries, Local Authorities, MSOAs and LSOAs (Generalised and Clipped only)
• All coordinates in EPSG:4326/WGS84 (rather than EPSG:27700/OSGB 1936)
• At least 60 megabytes installed
• Normalises postcodes to 7-character form

Examples

Details for a postcode

tibble(MyPostcode = "CF10 3NQ") %>% 
  add_fields_based_on_postcode(prefix="My", fields=c(
    "ElectoralWardName", 
    "LocalAuthorityName", "LocalAuthorityNameWelsh", 
    "CountryName", "CountryNameWelsh", 
    "MSOA11Name", "MSOA11NameWelsh"))

# A tibble: 1 × 8
#  MyPostcode MyCountryName MyCountryNameWelsh MyLocalAuthority… MyLocalAuthorit…
#  <chr>      <chr>         <chr>              <chr>             <chr>
# 1 CF103NQ    Wales         Cymru              Cardiff           Caerdydd
# … with 3 more variables: MyElectoralWardName <chr>, MyMSOA11Name <chr>,
#   MyMSOA11NameWelsh <chr>

All Welsh LSOAs with boundaries

welsh_lsoas <- all_codes_with_fields("LSOA11", "CountryName", "Boundaries") %>%
  filter(CountryName == "Wales")

library(sf)

welsh_lsoas <- welsh_lsoas %>% 
  convert_wkt_to_geometry()

library(ggplot2)

ggplot(welsh_lsoas) + geom_sf()
