Changes made: * Limited to a bounding box covering Marin County, San Francisco, and the East Bay as far as Alameda (37.69/-123.02 to 38.18/-122.20). * Records with a date_closed, or carrying an unresolved flag of closed, doesnt_exist, duplicate, delete, inappropriate or privatevenue, were removed. * Records not refreshed since 2022-01-01 were removed, as were records with neither a telephone number nor a website (except parks, which frequently have neither). * Foursquare category labels were mapped onto fourteen categories of this site's own, and records outside those categories were removed. * Retained fields were reduced to name, latitude, longitude and a category label, with coordinates rounded to five decimal places, and split into geographic tiles. Transit stop records in this dataset come from 511 SF Bay, not from Foursquare.
