Dataset Basics

Color digital orthophotography countywide coverage area at 1"= 100' scale with 0.5-foot pixel resolution. The orthophoto tiling format followed a modular layout, with each 1"= 100' scale image covering 2,500' x 2,500' defined by even NAD-83 Indiana State Plane Coordinate grid lines. Orthophoto tiles were clipped to eliminate overlap between adjacent tiles. The file size for each tile is approximately 75 MB. This digital orthophotography for Harrison County, Indiana, (including a 500 foot buffer) will be used in the enterprise GIS.

Data_Quality_Information:
Logical_Consistency_Report: This orthophoto image follows the modular layout, with each 1"= 100' scale image covering 2,500' x 2,500' defined by even NAD-83 Indiana State Plane Coordinate grid lines. The area of coverage for orthophoto imagery indicates the full area covered by the footprint feature class.
Completeness_Report: This feature class represents one image within the the complete set of data for the image tiles within Harrison County.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: In accordance with the specifications of the RFP, the digital orthophotography produced for this project was consistent across the entire project area, and met the specifications of the county's GIS system. The processes and data was produced at National Map Accuracy Standards (NMAS) for 1"= 100' scale mapping.

Process_Description: Woolpert acquired new ADS40 color aerial photography at 0.5-foot pixel resolution covering 484 square miles encompassing all of Harrison County. The aerial photography was acquired at an appropriate altitude capable of producing 1"= 100' scale countywide digital orthophotography mapping at 0.5-foot pixel resolution. Woolpert acquired Harrison County, Indiana, in the Spring of 2008. All digital imagery was acquired at a sun angle meeting or exceeding 30 degrees.

Process_Description:
Woolpert targeted ± 20 existing horizontal and vertical ground control points and provide airborne GPS to support the digital orthophotography mapping production.

The horizontal datum used for this project was North American Datum 1983 (NAD83), Indiana State Plane Coordinate System, East Zone, and expressed in U.S. Survey Feet. The vertical datum used for this project was North American Vertical Datum 1988(NAVD88). This control was sufficient to meet the required accuracy necessary to support the subsequent mapping.

Process_Description: Woolpert produced a new color digital orthophotography countywide coverage area at 1"= 100' scale with 0.5-foot pixel resolution. The orthophoto tiling format followed a modular layout, with each 1"= 100' scale image covering 2,500' x 2,500' defined by even NAD-83 Indiana State Plane Coordinate grid lines. Orthophoto tiles were clipped to eliminate overlap between adjacent tiles. The file size for each tile was 75 MB. Woolpert used an interactive mosaicking process for tone balancing and image mosaicking. Full tiles were used for both the interior and perimeter of the project area. The above digital orthophotography will be in .TIFF format with a .TIFF world file for geo-referencing.
