Mapping & GIS

A geographic information system (GIS) allows us to view, understand, interpret, and visualize data in many ways that reveal relationships, patterns, and data trends.

A sophisticated mapping and analysis software, GIS allows the user to analyze spatial data related to land use, transportation, natural resources, utilities, and long-range planning. GIS is an important tool in managing, planning, evaluating, and maintaining transportation systems. The main purpose of GIS services at SLOCOG is to support the regional land use model, regional travel demand model, and understand socio-demographic trends based on census data. Other key aspects of GIS activities at SLOCOG include maintaining and updating spatial data for regional transit services; bikeway and pedestrian infrastructure; land use and housing information; and socio-demographic information.


SLOCOG maintains the following GIS datasets:

  • Census 2010 block-level

  • Census 2010 tract-level

  • Transit Routes

  • Transit Stops

  • Bikeways (except Class I)

  • Bikeways (Class I)

  • Pedestrian Network (sidewalks, crossings, network links)

  • Pedestrian Network (signals, network junctions)

Shape files are available for download as zip files HERE. Some of the zip files will contain associated layer files. Excel files listing shape file attribute fields are also available for download.
