The 2005 Statewide Color Orthophotography Project developed seamless, accurate statewide aerial photography and elevation data for use in a GIS. All data are very high resolution and accuracy – meeting the needs of the most demanding users, like local government.

Color Orthophotography

Description: statewide coverage of natural color orthophotography at 1-foot and 6-inch pixel resolution

Resolution: 79 counties delivered at 1-foot resolution (5’ or better accuracy); 13 counties delivered at 6-inch resolution (2.5’ or better accuracy). See County Buy-Ups for more specifics.

Projection: Indiana State Plane (appropriate zone, east/west), NAD83/1988 adjustment

Data Format: uncompressed TIFF format (.tif) tiles; compressed MrSID generation III file format (.sid)

Delivery Method: delivered as 92 individual county coverages with a minimum of one full tile overlap with surrounding counties; single individual county coverages delivered on DVD to each respective county; unless otherwise arranged, delivered to the point of contact as identified by the county Emergency Management Director in their 2004 homeland security grant application (county is responsible for data distribution within their jurisdiction); one complete set delivered to state on external hard-drive; one complete set delivered to the Indiana Geographic Information Council

Color-Infrared Orthophotography

(1-meter resampled)

Description: statewide coverage of color infrared orthophotography resampled from natively collected 1-foot and 6-inch CIR imagery

Resolution: 1-meter pixel resolution

Projection: UTM coordinates, Zone 16, NAD83/1988 adjustment

Data Format: compressed MrSID generation III files, with world files, and uncompressed TIFF file formats (.tif) delivered in USGS quarter quadrangle (3.75 minutes) tiles

Delivery Method: one set on external hard drive and one set on DVD delivered to State; one set on DVD delivered to each county

Digital Surface Model (DSM)

Resolution: 1- and 2-meter post spacing (variable based on terrain)

Projection: State Plane coordinates, Zone 16, NAD83/1988 adjustment

Data Format: Imagine .IMG Format

Delivery Method: one set on external hard drive and one set on DVD delivered to State; one individual county set on DVD delivered to each county
