Roadway Network Data Base Microsoft SQL Server Database ESRIs ArcGIS and SDE Technology Project kickoff – March 2000 Design/Prototype – Fall 2002 Project initiative began Summer 2004 Data development began Spring 2005 Roll-out January 2007

Project Plan Conceptual Design Physical Design Pilot project and testing Framework development Populating data base

Project Goals Maintain and develop the database simultaneously Framework for developing local databases & applications Build a product that will be compatible with Mn/DOT data and establish a protocol to share new linework with Mn/DOT to facilitate updating of state base map

Project Goals Identify our own Unique ID for Anchor Points and Anchor Sections RNDB represents as-built roadways - Base map represents platted Create a process for retiring Anchor Points and Anchor Sections for historical reference

History vs Today

Example of RNDB Editing
