      <abstract>The Gallia County Digital Orthoimagery Project:
The project being performed in 2017 &amp; 2020 for Gallia County is a countywide orthoimagery update project.  Existing ground control and LiDAR will be utilized to provide the County a very economical orthoimagery product.
In the Spring of 2017, Gallia County obtained new orthoimagery covering (+/- 471.4 sq. miles). The aerial imagery was collected during leaf-off conditions at a minimum resolution of 3-inch.  The orthos are delivered as a countywide dataset, consisting of 1,250' x 1,250' uncompressed 8-bit, 4-band GeoTIFF files. Along the perimeter of the project area, ortho-imagery is buffered at 100-feet. The eastern side of the county will be defined as the farthest bank of the river, so the 100-foot buffer will be beyond the river’s farthest bank.  Any orthoimagery tile that is contained within or touching this 100-foot buffer will be provided as a full image tile. Products produced were 4-band, 8-bit orthophotos with a 0.25-foot ground sample distance GSD, countywide MrSIDs (RGB - 20x and 100x; CIR - 20x and 100x), and tile index provided as ESRI shapefile. Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with DMC II-230 digital cameras and rectified using LiDAR data. The file naming convention is as follows: bsxxxyyy (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.</abstract>
      <purpose>Gallia 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>
