Parking Lots

SafeGraph Parking Lots is a collection of premium geometry rows depicting the shape and size of surface parking lots in the U.S.

Parking Lots Schema

parking_lots.csv [reference file name for enterprise deliveries]

Column Name	Description	Type	Example
`placekey`	Unique and persistent ID tied to the parking lot. See Placekey for details on placekey design.	String	`222-222@222-222-222`
`latitude`	Latitude coordinate of the parking lot.	Float	`36.714767`
`longitude`	Longitude coordinate of the parking lot.	Float	`-121.662912`
`polygon_wkt`	The shape of the parking lot, formatted as Well-Known Text (WKT). See polygon_wkt for more details.	String	`Polygon ((-121.663310 36.715207,` `…, -121.663310 36.715207))`
`wkt_area_sq_meters`	The calculated area of the `polygon_wkt` rounded to the nearest square meter.	Integer	`184`
`related_poi`	The placekey(s) of the POI(s) we believe to be serviced by this parking lot. Note that a single parking lot often services more than one POI, and sometimes, more than one parking lot services a single POI. This is the inverse of the `related_parking` column in SafeGraph Places.	List	`[zzz-223@222-222-222, zzz-225@222-222-222]`

When our Parking Lots data is licensed with SafeGraph Places or SafeGraph Geometry, a premium column called related_parking is appended to the end of the schema to show the relationship between places and the surrounding parking lot(s) likely serving those POIs.

~6M U.S. places currently have an associated parking lot(s) mapped in the related_parking column.
