      <abstract>The Highland County, OH Orthoimagery Project consists of the following tasks:
New countywide 1”=100’ scale 8-bit, 4-band (R,G,B,NIR) stacked orthoimagery with a 6-inch pixel resolution (557.7 sq miles)
New 1”=100’ scale 8-bit, 4-band (R,G,B,NIR) stacked orthoimagery with a 3-inch pixel resolution (27.8 sq miles) covering 8 separate cities/villages within Highland County
New ground control were collected to support the 1”=100’ scale orthoimagery.

This task was performed on February 26, 2017 covering the entire Highland County (+/-558  sq. miles). Products produced were 4-band, 8-bit orthophotos with a 0.5-foot ground sample distance (GSD). The aerial imagery was collected during leaf-off conditions at a minimum resolution of 6-inch resolution.  The orthos are delivered as a countywide dataset, consisting of 2,500' x 2,500' uncompressed 8-bit, 4-band color GeoTIFF files. Along the perimeter of the project area, ortho-imagery is buffered at 100-feet. 
Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with DMCIIe digital cameras and rectified using LiDAR data. The file naming convention is as follows: asxxxyyy (Ohio South Zone); Please note that xxx and yyy represent the easting and northing coordinates (respectively) in state plane feet. Each GeoTIFF ortho file is approximately 100 megabytes in size. Any orthoimagery tile that is contained within or touching this 100-foot buffer will be provided as a full image tile.
</abstract>
      <purpose>Highland County, OH has a goal to develop and/or update their existing orthoimagery geospatial dataset for use by city agencies, other levels of government, academia, and the general public, and to provide these datasets for inclusion to OGRIP.  OGRIP is a State of Ohio resource for geographic information technology users.</purpose>

        <procdesc>The Intergraph Z/I DMC-II Airborne Digital Frame Camera collecting multiple spectral bands. The imagery for this task order was acquired using the Intergraph Z/I DMC-II Airborne Digital Frame Camera which uses Z/I Inflight Flight Navigation System and Z/I gyro-stabilized camera mount along with a NovAtel GNSS dual frequency receiver and NovAtel LN-200 series inertial measurement unit (IMU) for the measurements of the camera position and orientation during flight operations. The IMU/Airborne GNSS data was reduced using NovAtel's Inertial Explorer v8.60 software package. All of the source imagery was initially processed in Leica's FramePro software for image frame generation, and then final processed using the ImageStation Automatic Traiangulation (ISAT) software package. This package provides the capability to perform digital image processing, aerial triangulation, and image rectification. The imagery were ortho rectified to newly collected LiDAR digtial elevation model (DEM) data. The individual rectified strips of ortho rectified imagery were then mosaicked together to form a seamless imagery database over the entire task order area using the OrthoVista software by Inpho GmbH. The final digital orthophoto imagery (DOI) were extracted using OrthoVista.</procdesc>
