      <abstract>2012 City of Columbus Digital Orthoimagery Project – In the spring of 2013 City of Columbus obtained new orthoimagery covering the entire city service area. Products produced were 4-band, 8-bit orthophotos with a 0.25-foot ground sample distance (GSD). The aerial imagery was collected during leaf-off conditions at a minimum resolution of 3-inch resolution.  The orthos are delivered as a citywide dataset, consisting of 1,250' x 1,250' uncompressed 8-bit, 4-band color geotiff files.  Horizontal accuracy is based upon NMAS Standards for 1"=100' scale base mapping. All ortho tiles are full image tiles.  Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with Leica ADS80 digital cameras and rectified using LiDAR data. 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 the City of Columbus and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data.

      <purpose>The City of Columbus and the state of Ohio have a goal to develop and maintain a seamless ortho 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 v1.3 software package. All of the source imagery was processed using the Leica XPRO (V5.2) 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>
