      <abstract>The Union Co, OH-2018-2020 Countywide Orthos project consist of the following: 
        The Union County, OH Orthoimagery Project will consist of the following:
        New countywide 8-bit, 4-band (R,G,B,NIR) stacked orthoimagery with a 3-inch pixel resolution.
        The project being performed in 2018 for Union County is a countywide orthoimagery update project. Existing ground control and DEM data will be utilized, along with additional new ground control to provide the County a very economical orthoimagery product.
        
        2018 Union County Digital Orthoimagery Project – In Spring of 2018, Union County obtained new orthoimagery covering approximately 437 square miles. Imagery was collected with a Intergraph Z/I DMC-II digital camera and rectified using lidar data. The aerial imagery was collected during leaf-off conditions at a minimum resolution of 3-inches. Products produced include 4-band, 8-bit orthophotos with a 0.25-foot ground sample distance (GSD). Orthoimagery data was delivered as a countywide dataset, consisting of 1,250' x 1,250' uncompressed 8-bit, 4-band color GeoTIFF files. All ortho tiles are full image tiles. The file naming convention is as follows: bnxxxyyy (Ohio North 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 the Union County and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data.</abstract>
      <purpose>Union 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 Triangulation (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 digital 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>
