get_stops_sf: Convert GTFS Stops Table to Simple Features (sf) Format

In GTFSwizard: Exploring and Manipulating 'GTFS' Files

Convert GTFS Stops Table to Simple Features (sf) Format

Description

'get_stops_sf' converts the stops table in a 'wizardgtfs' object into a simple features ('sf') object, making it suitable for spatial analysis. This function checks the format of the 'stops' data and structures it as point geometries.

Usage

get_stops_sf(gtfs)

Arguments

gtfs	A 'wizardgtfs' object containing a 'stops' table or the stops table itself as a data frame.

Details

- When the input 'stops' table is not in 'sf' format, this function converts it to 'sf' by using the coordinates in the 'stop_lon' and 'stop_lat' columns.

- The resulting 'sf' object is assigned a CRS of WGS 84 (EPSG:4326) for geographic compatibility.

- If the 'stops' table is already in 'sf' format, the function simply reassigns the CRS and returns it unchanged.

Value

An 'sf' object with stops as point geometries or a 'wizardgtfs' object.
