About the Baltimore Region GIS Committee

The Baltimore Region GIS Committee (BRGISC) is a working group for GIS staff in BMC's member jurisdictions to come together to collaborate and exchange ideas on geospatial matters that affect the entire region. Founded in 2009, the BRGISC meets every other month to discuss state and local GIS activities, coordinate on regional projects, and provide educational and networking opportunities for its members. GIS staff at BMC act as a liaison between BMC's member jurisdictions to ensure they are kept updated on state policies and projects that affect local GIS operations. BMC staff also advocate at state meetings on behalf of local GIS interests.

BRGISC activities include:

  • Monitoring state GIS activities and policies and discussing their impact on local GIS operations
  • Advising state agencies on GIS issues that affect local GIS staff
  • Fostering cooperation, collaboration, and communication on GIS-related issues among local, regional, state, and federal agencies in the Baltimore area
  • Providing opportunities for state agencies, federal agencies, and other groups to bring their ideas to the entire region while giving local government GIS staff a chance to provide feedback on large-area projects that may affect them
  • Coordinating and facilitating the sharing of geospatial data among BMC member jurisdictions
  • Creating partnerships and project-level planning for geospatial data projects involving multiple jurisdictions
  • Creating an environment where GIS staff from local governments can share work experiences and project solutions
  • Identifying opportunities for Committee members to address common GIS training needs cooperatively with each other and other groups and agencies

Key Projects

Baltimore Region Combined Addressing Project

The Baltimore Region GIS Committee's Regional Centerline and Address Point Project is one of the first of its kind in the state of Maryland, making authoritative local cross-jurisdictional address and street GIS data available to participating counties and municipalities. BMC collects centerline and address point data from the jurisdictions and processes it into a single regional addressing schema. Participating jurisdictions are also collaborating on conflating the centerline into a seamless regional layer. Jurisdictions with shared borders have created unofficial "snap-to points" where the jurisdictions agree to join up their centerline segments and create a single contiguous address range. This process is ongoing and when complete will not only greatly improve cross-jurisdictional geolocation, it will lay the groundwork for a future regional routable centerline.

BMC shares the regional address data with the MD Department of IT for use in iMap and other addressing applications. This process allows the state to get the data from eight jurisdictions at once in a schema of their own choosing. A regularly updated geocoder web service is available for use by BMC members as well as the public. There is also a web application that allows local GIS staff to view the data and get a clip of the address point data outside of their borders.

Imagery Acquisition

In 2010, BMC led a collaborative effort for the BMC member jurisdictions to fund and commission an independent aerial imagery survey for the region. BMC worked with the Emergency Numbers System Board and USGS to obtain funding as well as solicit proposals from outside consultants that met the planning needs of our member jurisdictions.
