City staff outlines public GIS tools including SF Parcel, crime maps and asset viewer
Summary
City GIS staff described publicly available mapping tools that provide parcel, crime and asset data, and explained how GIS supports departmental operations and the public's access to traffic counts, assessed values and infrastructure information.
City GIS staff explained the city's public geographic information system (GIS) tools and how residents can use them to find parcel data, crime information, infrastructure locations and other attribute data.
A city GIS presenter told the Board that GIS combines maps with underlying attribute data and can provide traffic counts for a street segment, assessed values for parcels and crime incidence for police districts. "If the public wants to access any particular information about their house or their neighborhood or the city, we point them to GIS," the presenter said.
The presenter described several public applications maintained by city staff: SF Parcel (the assessor's parcel application), a crime maps application that shows crimes in San Francisco for the last 90 days, an asset viewer that lets users click on map features to retrieve details such as supervisory district or nearest public facility, and the SF Line application supported for the Mayor's Office of Neighborhood Services that allows neighborhood-level drill-down to hospitals, police and fire stations.
The presenter said GIS supports departments' business needs, including the Department of Public Works and the Bureau of Street Use and Mapping, where staff can click on a street segment and receive attribute information to assist permitting and right-of-way decisions. The presenter noted public access via the internet saves staff time by allowing residents to retrieve information remotely rather than visiting city offices or relying on staff for lookups.
Why it matters: Public GIS tools give residents and city staff rapid access to parcel, asset and crime information and support operational decision-making by departments that manage infrastructure and permitting in the right-of-way.
Practical details recorded in the presentation include the examples above (traffic counts, assessed value, 90-day crime map) and the specific public applications: SF Parcel, crime maps, asset viewer and SF Line.
