Function to recategorise OSM infrastrcutre based on lighting presence.

Source: R/oi_is_lit.R

Determins whether or not a piece of OSM infrastructure is lit or not.

oi_is_lit(osm_sf, remove=FALSE)

Arguments

osm_sf

  • A sf and data.frame object containing OpenStreetMap infrastructure data.

remove

  • Boolean - If TRUE, features that do not have lighting are removed from the osm_sf before being returned.

Value

an sf object with oi_is_lit column added, indicating if the way is lit or not.

Details

This function adds a new column, openinfra_is_lit containing values "yes" , "no", whether or not the feature is lit. The value "maybe" is assigned when there is a lack of data to distinguish - not implying the presence or lack of lighting, but a lack of data to identify.

Note: the osm_sf must contain the following tags: c("lit", "lit_by_led")

Examples

data = example_data
example_output = oi_is_lit(data)
