Business Data


Gims purpose
GIMS Purpose

  • Central business data source

  • Centerline data source

  • Cartographic Support

  • CTAMS Input

  • Support for Planning Activities and Reporting Mandates




Improved data to roadway association
Improved Data to Roadway Association

  • Detail of features located along the roadway will increase.

  • Move from capturing number of features (stop signs, curves, intersections per segment, etc.) to actual location of features.



User needs
User Needs

Bridges

Normalized Data

  • Data are maintained in individual tables, limiting data redundancy

  • Attributes describe varying extents along a section of roadway

  • Graphic representations of attribute data are generated “on the fly”


Less redundancy in data maintenance
Less Redundancy in Data Maintenance
