State of Ohio Office of Information Technology, Ohio Geographically Referenced Information Program 20201207 raster In the Spring of 2020, Wood County obtained new orthoimagery covering the entire county (+/- 621.4 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. 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 Wood County and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data. Wood 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. 20200307 20200315 20200325 20200402 20200403 20200408 20200409 20200411 ground condition Complete As needed -83.893430 -83.407130 41.622141 41.161154 None Raster Orthophoto None United States Ohio Wood County This data set is in the public domain, and the recipient may not assert any proprietary rights thereto nor represent it to any one as other than a data set produced by Woood County and the Ohio Statewide Imagery Program.

The dataset is complete The 7.5cm (3-inch) orthoimagery will be 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. The Leica ADS100 Airborne Digital Sensor is a push-broom geometry sensor, collecting 12-bit data with 20,000 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. 20201207 Woolpert Geospatial Services mailing and physical address

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. 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 ft x 1,250 ft. 20201207 Woolpert Geospatial Services mailing and physical address
