MTC uses GIS for a variety of purposes throughout the agency. Several examples are listed below.
MTC maintains an extensive GIS database, in machine readable and hard copy formats, to support regional transportation planning. These various data files, as well as maps and other graphic pieces, are public records, and MTC welcomes their use by the planning community throughout the region.
MTC data is collected and analyzed by MTC staff. The appropriate use of such data in other planning programs and studies must be determined entirely by the planners and analysts of the firm or agency undertaking such projects. MTC makes no warranties, expressed or implied, of the appropriateness or accuracy of any results or opinions derived from any project not conducted or sponsored by MTC utilizing MTC's data.
MTC has acquired or developed a variety of GIS data to support our GIS activities. Unless restricted by licensing or non-disclosure agreements, these data are available for distribution to others. To browse our data catalog and download the most frequently requested data, go to our Open Data page.
MTC has standardized on Universal Transverse Mercator (UTM), Zone 10N, NAD83 for all analysis based projects. However, much of the data stored on MTCs Data Portal is stored in WGS 1984 Web Mercator (WKID 3857). This format is more widely used for web mapping services. All units are measured in meters.
MTC currently licenses the Tom Tom MultiNet base map database. This database is used as a common basemap across all of MTC's spatial analytics and map publications. If you are a contractor or a consultant working on a project for MTC, the data can be obtained for MTC project work only. Consultants and contractors must fill out this form: Data Sharing Form to obtain the data.
If you are a partnership agency of MTC, the data may be acquired from MTC (at MTC's discretion) for no fee. Partnership agencies are required to fill out this form: Partnership Agency Data Sharing Form to obtain the data. This form must be updated annually.
A Partnership agency is defined as any non-private transportation or planning organization, transit operator, public agency or transportation research institution that serves one or more of the nine Bay Area counties (Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano or Sonoma) or a neighboring county. This includes Bay Area transit operators, congestion management agencies, ABAG, RIDES for Bay Area Commuters, the Bay Area Air Quality Management District, and Bay Area city and county government agencies.
MTC uses the ESRI suite of GIS software, including ArcGIS Desktop 10.x (Advanced, Standard and Basic), and ArcGIS Server 10.x. For travel demand modeling (TDM) purposes, MTC uses Cube Voyager, MINUTP, TP+ and VIPER. Additional statistical analysis is performed using R, SAS and EXCEL.
