      <abstract>2017 OSIP Base Digital Orthoimagery Project – 
The OSIP project is divided into four (4) project areas. Area 1 (+/- 9,862 square mile)  is the northeast zone and performed in 2017. Area 2 (+/- 10,606 square miles) will be the western zone and performed in 2018. Area 3 (10,405) will be the central zone and performed in 2019. Area (+/- 410,392) will be the southeast zone and performed in 2020.
The new 3-band orthoimagery will encompass the entire land area of the State of Ohio, or ~41,276 square miles. The tile border will be 1,000 feet beyond the state boundary with the following exceptions. The tile border with the states of Kentucky and West Virginia along the Ohio River shall be buffered a minimum distance of 1,000 feet or to the opposite river bank, whichever distance is greater. Border areas of the State proximate to Lake Erie, as well as islands, shall be buffered beyond the shoreline a minimum distance of 2,500 feet.
Area 1: The aerial imagery was collected during leaf-off conditions at a minimum resolution of 0.5-foot.  The orthos are delivered as countywide datasets, consisting of 5,000' x 5,000' uncompressed 8-bit, 3-band color geotiff files. Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with VisionMap A3 Edge digital camera systems and rectified using existing LiDAR data. The file naming convention is as follows: nxxxxyyy (Ohio North Zone); Please note that xxxx and yyy represent the easting and northing coordinates (respectively) in state plane feet. The naming convention is based upon the previous OSIP project.  Each geotiff ortho file is approximately 100 megabytes in size. 
Ashtabula County (Area 1): The aerial imagery was collected during leaf-off conditions at a minimum resolution of 0.5-foot.  The orthos are delivered as countywide datasets, consisting of 2,500' x 2,500' uncompressed 8-bit, 4-band color geotiff files. Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with Leica ADS100 digital camera systems and rectified using existing LiDAR data. The file naming convention is as follows: anxxxyyy (Ohio North Zone); Please note that xxxx 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 OGRIP and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data.</abstract>
      <purpose>The State of Ohio has a goal to develop and/or update certain geospatial data sets for use by state government agencies, other levels of government, academia, and the general public, and to provide these data sets for inclusion to OGRIP.  OGRIP is a resource for geographic information technology users inside Ohio and beyond.  Funds for the statewide orthoimagery program will come from state agencies.</purpose>

        <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 of 5 cm using the side-stepping gimbal technology. VisionMap's A3 Edge contains dual 300mm focal length telescopes (Red, Green, Blue x 2) that are optimized for capturing high altitude RGB 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 Waypoint's POSGNSS 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, and image rectification. The image frames were ortho rectified to existing LiDAR digtial elevation model (DEM) data. 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. The final digital orthophoto imagery (DOI) were extracted using OrthoVista.</procdesc>

        <procdesc>The Leica ADS100 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. The strips of 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>
