      <abstract>2011 OSIP Base Digital Orthoimagery Project - In the Spring of 2011, Woolpert obtained new aerial imagery covering 16 counties located in northeast Ohio (along the Lake Erie Shoreline (~6,990.9 sq. miles)). Products produced were 4-band, 8-bit orthophotos with a 1.0-foot ground sample distance (GSD). The aerial imagery was collected during leaf-off conditions at a minimum resolution of 1.0-foot.  The orthos are delivered as countywide datasets, consisting of 5,000' x 5,000' uncompressed 8-bit, 4-band color geotiff files.  Horizontal accuracy is based upon NMAS Standards for 1"=200' scale base mapping. Along the perimeter of the project area, ortho-imagery is buffered at 1,000-feet (state borders covered by land) and 2,500-feet along the Lake Erie Shoreline.  Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with Leica ADS40 (SH 51/52 and SH 81/82) digital cameras and rectified using 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. 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.

LiDAR was acquired Statewide to provide a solid and very accurate base to use during the image rectification process.  This same LiDAR can be supplemented with 3D breaklines to generate 2-foot and/or 4/5-foot contours.  The average post spacing between LiDAR points is 7-feet.  The flying altitude was ~7,300-feet AMT, with the targeted flying speed at ~170 knots.</abstract>
      <purpose>The state of Ohio has a goal to develop and maintain a seamless statewide base map, referred to as OSIP (Ohio Statewide Imagery Program). OSIP is an initiative partnered through several State Agencies (i.e. ODOT, ODNR, OEPA) through OGRIP. USGS is also a partner.  Data from this project forms the foundation of the statewide base map, and was developed primarily to support multi-use applications, including homeland security, emergency management, economic development, and the business of government.</purpose>

        <procdesc>The Leica ADS80-SH81/82 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’s ADS80 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 ADS80-SH81/82 multispectral scanner. The ADS80-SH81/82 utilizes the Leica’s 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’s IPAS Pro software package (V1.3). All of the source imagery was processed using the Leica XPRO (V5.0.1) 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 digtial 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 (V4.5) by Inpho GmbH. The final digital orthophoto imagery (DOI) were extracted using OrthoVista.</procdesc>
