This dataset was developed to provide accurate street centerlines for Indiana, as part of Indiana's annual GIS Data harvest Data Sharing Initiative (IDSI) of the Indiana Geographic Information Office (IGIO). This data layer is an Esri file geodatabase polyline feature class that contains street centerlines maintained by county agencies in Indiana. It was released by the Indiana Geographic Information Office (IGIO) on December 1, 2022. The IGIO compiled the data as part of the Indiana Data Harvest program between the Indiana Geographic Information Council (IGIC) and all Indiana counties to provide the most accurate framework data for the citizens of Indiana.
