SHA Project History

The Shared Centerline Program started in 2001
with the Maryland State Highway Administration
(SHA) testing vertical integration of
transportation data using the Howard County
attributed centerline
SHA developed a methodology that would allow
sharing the common centerline from local
governments
SHA attaches a unique-ID onto each road segment
allowing simplification of future data exchange
as well as making the data model flexible

This is why a cooperative centerline was needed

Project History

Maryland State Highway Administration (MD-SHA)
and the Maryland Association of Counties (MACO)
received a 2005 Special Achievement in GIS award
for its outstanding use of geographic information
system (GIS) technology from ESRI
Later in 2005, ESRI President Jack Dangermond met
with SHA, sharing with the team that data
interchange may be enhanced with the new
capabilities being introduced into the ArcGIS
data server environment at the 9.2 release

Project History

The Cooperative Centerline Program has evolved
into the Federated, or Synchronized Street
Centerline Project, via the current Pilot between
SHA, Towson University and Anne Arundel,
Baltimore, Harford, Howard and Saint Marys
Counties

Maryland Statewide Addressing Initiative
Immediate Project Goals

To provide a unified, statewide road centerline
that supports addressing needs
To provide counties with a means to automatically
share an unrefined version (i.e., not for federal
reporting) of their street centerline data
To augment existing efforts of Maryland State
Highway Administrations federal reporting by
improving data access via a centralized
distribution node
To advance ESRIs mission in demonstrating the
data synchronization capabilities of ArcGIS
Server 9.2
To increase the efficiency of statewide highway
incident reporting.
Long Range Goal To establish a single,
statewide road centerline that supports
addressing, linear referencing, routing, and
cartography.

Project Benefits

Foundation for Marylands Spatial Data
Infrastructure
Unified, statewide addressing layer that supports
geocoding
Counties can geocode beyond their borders
States can leverage locally rich data
consistently
Elimination of the need for manual data exchange
via CD
Ability to establish a persistent replica that is
updated automatically
Ability to extract data for a specified geography
through a geodata service
Accessible by other applications that require
geocoding
Combining Web services through a Service Oriented
Architecture (SOA) approach
Builds upon established SHA database schema
