Lancaster, Pennsylvania (September 1, 2009) – geographIT has been selected by the Transportation Division of the Lancaster County Planning Commission to perform a system migration of its legacy GIS-T application from ArcView 3.x to ArcGIS 9.3.  The GIS-T legacy application, which geographIT developed, automatically loads and classifies predefined roadway, traffic, bridge, and accident data as event themes mapped to PennDOT's linear referencing system.  The program also provides a Query Builder wizard that enables the user to define, modify, and delete custom queries of event tables.  The new application will be developed with .NET 3.5 and ArcGIS 9.3.1 and will integrate PennDOT event data with Lancaster County's state routes, built from their local road centerlines using PennDOT network ID's and measures.
