Civil townships are a unit of local government, typically subordinate to the County. In Indiana, each township is served by an elected township trustee.Civil townships are primarily represented as Minor Civil Divisions (MCDs) in the source data by the US Census Bureau. Per the US Census, MCDs are the primary governmental or administrative divisions of a county in many states. This data mostly contains MCD boundaries, with some corrected township boundaries (see explanation below). On 1/3/2024, IGIO staff updated the boundaries and/or attributes of 6 townships: Center (Delaware Co), Mount Pleasant (Delaware Co), Eagle (Boone Co), Perry (Boone Co), Union (Boone Co), and Worth (Boone Co). The Delaware County townships were attributed as either Muncie City or Yorktown Town and had associated incorporated area boundaries overlapping the civil township boundary. Boone County had townships attributed as Zionsville City and Whitestown Town and had associated incorporated are boundaries overlapping the real civil township boundary. Civil township boundaries from the 2023 Data Harvest were used when possible to correct geometry, and the neighboring census township boundaries to maintain topology when needed. Eagle and Union townships do not have a populated GEOID since the corrected boundary does not correspond to a census MCD geography to avoid incorrect joins to census tabular data by end users.

Electric Service Territories (IURC) - Shows the Electric Service Territory (EST) boundaries in Indiana, maintained by personnel of the Indiana Utility Regulatory Commission (IURC). This layer is "live" and synchronized to automatically update whenever IURC personnel establish new boundaries.The layer was created to visually represent, as accurately as possible, the electric service territories served by the regulated electric service providers in the state of Indiana, pursuant to Cause Number 42868 (Indiana Utility Regulatory Commission) to establish an online GIS mapping environment to house, edit, and display visual interpretations or electric service territory rulings filed before and ruled by the Indiana Utility Regulatory Commission. The data represented in this layer is strictly a visual aide and a best interpretation of the legally approved Electric Service Territories as ruled by the Indiana Utility Regulatory Commission (IURC). These data are not legally binding or necessarily fully representative of the legal rulings.The following is excerpted from metadata provided by the IURC: "IN THE MATTER OF THE JOINT PETITION OF ELECTRICITY SUPPLIERS FOR (1) THE ESTABLISHMENT OF THE PROCEDURES TO APPROVE SERVICE AREA BOUNDARY AGREEMENTS UNDER IC 8-1-2.3-6(2) AND SERVICE CONSENTS UNDER IC 8-1-2.3-4(A), AND (2) MODIFICATION OF THE FORM AND MAINTENANCE OF MAPS OF ASSIGNED SERVICE AREAS ESTABLISHED PURSUANT TO IC 8-1-2.3-1, ET SEQ.
