US Census 2000 Block Group Geography modified to conform with SFGIS Library Geography (Streets, Lakes, et al). Water areas have been clipped from this layer. Please refer to the Federal Census for the latest data, these boundaries provided as a convenience.
All active addresses from the City's Enterprise Addressing System, including sub-addresses, such as units. Includes references to parcel and street centerline data. Updated nightly.See EAS Base Addresses for base addresses not including units.
Public and private colleges within San Francisco from National Center of Education Statistics data. College locations represented as boundaries. As of 2011. You can get updated institutional characteristics data at https://nces.ed.gov/ipeds/datacenter/DataFiles.aspx
Recorded parcel geography, both active and retired, with date recorded parcel was added, date recorded parcel was dropped/retired, date was added, dropped or altered re map layer. Contains geography created since the inception of the basemap in 1995, with some exceptions.
Active base addresses from San Francisco's Enterprise Addressing System, This dataset does not include sub-addresses, such as units, and does not include a block/lot value for each record. For units and block/lot values, see the "Addresses with Units - Enterprise Addressing System" dataset.
Status of review of datasets in the Facility System of Record, showing when departments have reviewed the datasets under their jurisdiction, when the datasets have been updated to incorporate any changes resulting from the review, and when the changes, if any, have been accepted by the department.
These footprint extents are collapsed from an earlier 3D building model provided by Pictometry of 2010, and have been refined from a version of building masses publicly available on the open data portal for over two years.The building masses were manually split with reference to parcel lines, but using vertices from the building mass wherever possible.These split footprints correspond closely to individual structures even where there are common walls; the goal of the splitting process was to divide the building mass wherever there was likely to be a firewall.
An arbitrary identifier was assigned based on a descending sort of building area for 177,023 footprints. The centroid of each footprint was used to join a property identifier from a draft of the San Francisco Enterprise GIS Program's cartographic base, which provides continuous coverage with distinct right-of-way areas as well as selected nearby parcels from adjacent counties.
