      <abstract>2012 Fairfield County Orthoimagery Project – In the spring of 2012 Fairfield County obtained new orthoimagery covering the entire county (+/- 508 square miles). Products produced were 4-band (R,G,B, NIR), 8-bit orthophotos with a 0.25-foot ground sample distance (GSD). The aerial imagery was collected during leaf-off conditions at a minimum resolution of 3-inch resolution.  The orthos are delivered as a countywide dataset, consisting of 1,250' x 1,250' uncompressed 8-bit, 4-band color geotiff files.  Horizontal accuracy is based upon NMAS Standards for 1"=100' scale base mapping. All ortho tiles are full image tiles.Imagery was collected with Leica ADS80 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. Orthoimagery and ancillary data products produced through this contract are public domain data.
</abstract>
      <purpose>The Fairfield County and the state of Ohio have a goal to develop and maintain a seamless ortho 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.</purpose>

        <procdesc>The Leica ADS80-SH81/82 Airborne Digital Sensor is a push-broom geometry sensor, collecting 12-bit data with 12,000 pixel swath coverage with up to a 5-centimeter spatial resolution. The sensor is capable of collecting multiple spectral bands and angles simultaneously. Leica’s ADS80 collects seven bands of imagery simultaneously: 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 this task order was acquired using the Leica ADS80-SH81/82 multispectral scanner. The ADS80-SH81/82 utilizes the Leica’s IPAS20 direct positioning and orientation system that is based on airborne GPS and inertial measurement unit (IMU) technology. The IPAS20 data were reduced using Leica’s IPAS Pro software package (V1.3). 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) were extracted using OrthoVista.</procdesc>
