      <abstract>2012 Preble County Digital Orthoimagery Project - On February 26, 2012 and February 27, 2012 Preble County obtained new orthoimagery covering the entire county (+/- 426 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.  Horizontal accuracy is based upon NMAS Standards for 1"=100' scale base mapping. Along the perimeter of the project area, ortho-imagery is buffered at 1,000-feet.  Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with Leica ADS80 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. Ownership of the data products resides with Preble County and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data.</abstract>
      <purpose>The state of Ohio has a goal to develop and maintain a seamless statewide base map, referred to as OSIP (Ohio Statewide Imagery Program). OSIP is an initiative partnered through several State Agencies (i.e. ODOT, ODNR, OEPA) through OGRIP. USGS is also a partner.  Data from this project forms the foundation of the statewide base map, and was developed primarily to support multi-use applications, including homeland security, emergency management, economic development, and the business of government.</purpose>

        <procdesc>The Leica ADS80-SH81/82 Airborne Digital Sensor acquires all digital, 12-bit data with the swath width and coverage area of a traditional film camera with up to a 5-centimeter spatial resolution. The sensor is capable of simultaneous acquisition of seven bands of imagery: three panchromatic CCD lines capture information in the forward, nadir and backward views from the aircraft, while four multispectral lines capture data in the red, green, blue, and near color infrared band. The imagery for the Preble County 2012 Ortho task order was acquired using the Leica ADS80-SH81/82 multispectral scanner. The fundamental resolution of the imagery was 0.5-foot. The ADS80-SH81/82 utilizes the Applanix POSAV direct positioning and orientation system that is based on airborne GPS and inertial measurement unit (IMU) technology. POSAV data were reduced using the Applanix POSPAC software package (V5.3). All of the source imagery was processed using the Leica XPRO (V5.0.1) software package. This package provides the capability to perform digital image processing, aerial triangulation, and image rectification. The strips of 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 (V4.5) by Inpho GmbH. The final digital orthophoto imagery (DOI) 2500 x 2500 feet tiles based on the Ohio South State Plane Zone coordinates, were extracted using OrthoVista.</procdesc>
