      <abstract>In the Spring of 2022, Huron County obtained new orthoimagery covering the entire county (+/- 496.4 sq. mi). The aerial imagery was collected during leaf-off conditions with a 3-inch pixel resolution. Imagery was collected with the A3 Airborne Digital Sensor. Along the perimeter of the project area, ortho-imagery is buffered at 100-feet. Existing ground control and lidar data will be utilized to provide the County the most economical product. The orthos are delivered as a countywide dataset, consisting of 1,250' x 1,250' uncompressed 8-bit, 4-band color GeoTIFF files. The file naming convention is as follows: bnxxxxyyyy (Ohio North Zone); Please note that xxxx and yyyy represent the easting and northing coordinates (respectively) in state plane feet. Each GeoTIFF ortho file is approximately 100 megabytes in size. Additional deliverables include countywide color and color infrared MrSID (Multi resolution Seamless Image Database) images (20x and 100x compressions), FGDC compliant metadata per file, and tile index provided in ESRI shapefile format. Ownership of the data products resides with Huron County and the state of Ohio.</abstract>
      <purpose>Huron 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>

      <horizpa>The 7.5cm (3-inch) orthoimagery was produced by Woolpert to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 11cm RMSEx / RMSEy Horizontal Accuracy Class which equates to Positional Horizontal Accuracy = +/- 27.6cm (+/- 0.9ft) at a 95% confidence level.</horizpa>

        <procdesc>The VisionMap A3 EDGE Aerial Camera System is a large format frame-based sensor, collecting 12-bit RGB data. The sensor is capable of collecting multiple spectral bands and angles simultaneously at image pixel resolutions as small as 5 cm using the side-stepping gimbal technology. VisionMap's A3 Edge contains dual 300mm focal length telescopes that are optimized for capturing high altitude RGB and/or RGBNIR imagery. The A3 Edge camera system has no ITAR restriction concerns. The imagery for this task order was acquired using the VisionMap A3 Edge camera system. The airborne GPS data were reduced using Inertial Explorer’s trajectory software package. All of the source imagery was processed using the VisionMaps's LightSpeed software package. This package provides the capability to perform digital image processing, aerial triangulation, image rectification and mosaicking.</procdesc>

        <procdesc>The individual rectified frames of ortho rectified imagery were then mosaicked together to form a seamless imagery database over the entire task order area through the VisionMap’s LightSpeed software package. OrthoVista software was used for the final imagery processing and tiling. 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 ft x 1,250 ft.</procdesc>
