For researchers, planners, journalists and anyone who wants to put San Francisco’s past zoning in a GIS program of their own.

What is here

Lots are today’s parcels, each tagged with the district the historic map put it in. Districts are those same lots dissolved into one shape per district. Scans are the historic map pages themselves, warped to line up with today’s street corners: one citywide image, and the individual sheets. Black-and-white scans are tinted to the paper colour, and printed border rules and binding shadows are erased; nothing is traced or drawn on them.

Lots and districts come as GeoJSON, GeoPackage and Shapefile, in WGS84 (EPSG:4326). The GeoPackage also carries a copy in California State Plane (zone III, feet). Each download includes a README and the license.

This is a reconstruction from scanned maps, read by a program, with some corrections by hand, not an official record. Read how the maps were made and how accurate they are before relying on them.
