Abstract
![]() Creating a Transportation Database Using a Linear Referencing System Track: Transportation Author(s): Tim Gahagan, Raja Andela As Northwest Ohio's Metropolitan Planning Organization, the Toledo Metropolitan Area Council of Governments (TMACOG) works with transportation data from several counties in Ohio as well as Michigan. With the need to manage this data effectively, TMACOG has developed an Integrated Transportation Database (ITD), which will house all of the regional transportation data in a single set of relational databases. These datasets can then be mapped using a Linear Referencing System (LRS) built on existing DOT frameworks. Tools available in ArcInfo 9 are used to build the LRS as well as conflate attributes from multiple geographic networks into one system. Once the ITD is completed, it will reduce the time needed to do various GIS analyses, produce maps, and ease the transfer of data among participating agencies. This presentation will discuss the design of the database, various conflation techniques used, and the quality control of the database.
