The standards you’ll find here were developed by the IGIC Standards and Recommendations Committee in cooperation with the GIS community in Indiana. The goal of these standards is to facilitate the collection, maintenance and analysis of geographic information across public, private and government entities.
Their adoption would assure that your data are internally consistent, and consistent with others developing data for the same or similar geographic extents. It is not our intent to suggest that one standard be implement by all – everyone should select what works best for their own needs.
Although not formally an adopted standard, a CAD-GIS integration workflow template has been developed by IGIC workgroups.
