The orthoimagery covers the entire land area of the southern tier of Ohio (approximately 17,000 square miles), excluding Highland, Pike, Ross, Adams and Scioto Counties, which due to weather, will be flown in 2008. The orthos are delivered in county sets, consisting of 5,000' x 5,000' uncompressed 24-bit natural color geotiff files. Horizontal accuracy is based upon NMAS Standards, with the 1"=200' scale (1-foot imagery) based upon an accuracy of +/- 5.0-feet and the 1"=100' scale (0.5-foot imagery) based upon an accuracy of +/- 2.5-feet. Where the State borders other states (land only), the entire border of the State is buffered by at least 1,000-feet. Along the Ohio River ortho coverage is buffered beyond the opposing shoreline by an average distance of 200-feet. Adjacent flight lines overlap by an average of 30 percent. Imagery was collected with Leica ADS40/51/52 digital cameras and rectified using LiDAR data. The file naming convention is as follows: Sxxxxyyy = 1"=200' scale imagery (1.0-foot resolution) located in the Ohio State Plane Coordinate System (Sorth Zone). Nxxxxyyy = 1"=200' scale imagery (1.0-foot resolution) located in the Ohio State Plane Coordinate System (Nouth Zone). asxxxyyy or anxxxyyy= (e.g., 6-inch); Please note that xxxx and yyy represent the easting and northing coordinates (respectively) in state plane feet. Each geotiff ortho file is approximately 75MBs in size. Ownership of the data products resides with the State of Ohio and counties that elected bo "buy-up". Orthophotography 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. 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. The delivery of the LiDAR DEM will be based upon the 5,000' x 5,000' ortho tile layout, with the same naming convention used for both the imagery and LiDAR. Each LiDAR tile will be delivered in ArcGRID (ASCII), Raster and LAS Formats.

The following checks were performed. - The ground control and airborne GPS data were validated through a fully analytical bundle aerotriangulation adjustment. - The LiDAR DEM data was checked against the project ground control. The technical staff confirmed the accuracy of the points during initial processing - Digital orthophotography was validated through an inspection of edge matching and visual inspection for image quality. The following methods are used to assure imagery accuracy. - Use of IMU and ground control network utilizing GPS techniques. - Use of airborne GPS in conjunction with the imagery and LiDAR acquisition. - The following software is used for validation of the imagery and surface modeling - Aerotriangulation - Leica - LiDAR DEM Data - Terrascan, TerraModeler, Leica - Digital Orthophotography - Microstation, IRASC, OrthoPro, OrthoVista, ArcGIS, Leica GPro - MicroStation - ESRI - ArcInfo - ERDAS Imagine - Woolpert Proprietary software - Adobe - Photoshop The 1"=200' scale orthophotos were created to meet 5.0-foot horizontal accuracy, meeting NMAS. The 1"=100' scale orthophotos were created to meet 2.5-foot horizontal accuracy, meeting NMAS. The LiDAR DEM was acquired to meet +/- 1-foot vertical accuracy. This is suitable for rectification of digital orthophotography and for the creation of 2- and 5-foot contours (with the addition of 3D compiled breaklines). The aerial imagery acquisition for the State of Ohio was flown to support the creation of digital orthophotography with a 0.5-foot and 1-foot pixel resolution. The 0.5-foot pixel ortho imagery was flown at an approximate altitude of 4,800-feet AMT. The 1-foot pixel ortho imagery was flown at approximately 9,600-feet AMT. Imagery was flown with an average 30% overlap between flight lines All imagery was collected using the Leica ADS40/51/52 digital camera system.
