The IndianaMap is a resource for geographic information technology users inside Indiana and beyond. The IndianaMap is an initiative of the Indiana Geographic Information Council, Inc. (IGIC), Indiana's statewide GIS coordination council. Data from this project form the foundation of the base map and are developed primarily to support multi-use applications, including homeland security, emergency management, economic development, and the business of government. Funds for the statewide orthophotography program come from state agencies, local governments, and grants. 20230211 20230402 ground condition Complete As needed -88.1656 -86.1862 41.7685 37.7628 None Raster Orthophoto Imagery None United States Indiana No restrictions apply to this data.

The orthoimagery is visually inspected by Sanborn for completeness. The 0.5ft orthoimagery will meet the ASPRS Horizontal Accuracy Class of RMSEx and RMSEy of 1.0ft. The 0.25ft orthoimagery will meet the ASPRS Horizontal Accuracy Class of RMSEx and RMSEy of 0.5ft. Sanborn 20230717 Indiana Statewide Imagery Program raster digital data Digital 20230717 ground condition Orthophoto Digital aerial imagery was acquired to produce 4-band, 8-bit ortho-imagery. The 0.5ft ground sample distance (GSD) digital aerial imagery was acquired using Vexcel UltraCam Eagle Airborne Digital Sensors. Imagery from these frame sensors were used for the subsequent production of 4-band, 8-bit orthophotos. Once the acquired imagery was orthorectified to the ground control and terrain data, orthoimagery was delivered as a countywide dataset consisting of 2,500' x 2,500' GeoTIFF files. Each GeoTIFF orthoimagery file is approximately 100 megabytes in size. The 0.25ft ground sample distance (GSD) digital aerial imagery was acquired using Vexcel UltraCam Eagle Airborne Digital Sensors. Imagery from these frame sensors were used for the subsequent production of 4-band, 8-bit orthophotos. Once the acquired imagery was orthorectified to the ground control and terrain data, orthoimagery was delivered as a countywide dataset consisting of 1,250' x 1,250' GeoTIFF files. Each GeoTIFF orthoimagery file is approximately 100 megabytes in size. 20230717 The Sanborn Map Company, Inc.
