      <abstract>In the Spring of 2019, Champaign County obtained new orthoimagery covering the entire county (+/- 430.2 sq. mi). The aerial imagery was collected during leaf-off conditions with a 3-inch pixel resolution. Imagery was collected with the Leica ADS100 Airborne Digital Sensor.  Along the perimeter of the project area, ortho-imagery is buffered at 100-feet. New ground control is collected and used along with existing control and existing DEM data to provide the County the most economical, but current product. The orthos are delivered as a countywide dataset, consisting of 1,250' x 1,250' uncompressed 8-bit, 4-band color GeoTIFF files. Additional deliverables include countywide Multi resolution Seamless Image Database MrSID imagery (individual RGB - 20x and 100x; individual CIR - 20x and 100x), color and color infrared MrSID images (20x compression) for each township, FGDC compliant metadata per file, and tile index provided in ESRI shapefile format. 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. Ownership of the data products resides with Champaign County and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data.</abstract>
      <purpose>Champaign County, OH has a goal to develop and/or update their existing orthoimagery geospatial dataset for use by county 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.

        <procdesc>The imagery for this task order was acquired using the Leica ADS100 System. The 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 ADS100 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 ADS100 multispectral scanner. The ADS100 utilizes the Leica 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 Inertial Explorer software package. All of the source imagery was processed using the Leica XPRO software package. This package provides the capability to perform digital image processing, aerial triangulation, and image rectification.</procdesc>

        <procdesc>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. Final orthophoto non-overlapping tiles were produced in GeoTIFF format (with World files) using a cell size of 3-inch and a tile size of 1,250’ x 1,250’.</procdesc>
