The LiDAR covers the entire land area of the southern tier of Ohio (approximately 17,832 square miles. The LiDAR is delivered in county sets, consisting of 5,000' x 5,000' size tiles. Where the State borders other states (land only), the entire border of the State is buffered by at least 1,000-feet. Adjacent flight lines overlap by an average of 30 percent. Along the Lake Erie Shoreline ortho coverage is buffered beyond the shoreline a minimum distance of 2,500-feet. LiDAR was collected with Leica ALS50 digital LiDAR Systems. The file naming convention is as follows: Nxxxxyyy = 5,000' x 5,000' LiDAR Tiles located in the Ohio State Plane Coordinate System (North Zone). Sxxxxyyy = 5,000' x 5,000' LiDAR Tiles located in the Ohio State Plane Coordinate System (South Zone). Please note that xxxx and yyy represent the easting and northing coordinates (respectively) in state plane feet, The naming convention for each LiDAR tile is based upon (the bottom most-left pixel). Ownership of the data products resides with the State of Ohio. 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 following LiDAR classes are part of the LiDAR files. Class 1 (Default) - These points are what is left of the remaining points after the ground classification. These would contain cars, buildings, parts of vegetation, possible ground (not consisting of bare earth surface), etc. Class 2 (Ground) - These are bare earth points. They are classified through an automated processing, as well as the manual review. Class 5 (Non-Ground) - These points consist of the first and subsequent returns from the LIDAR pulse. These points that are most likely to signify vegetation returns or points identified to not be on the ground surface. Class 7 (Low point) - These are points that are below ground surface. Most of them are outliers. 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) through OGRIP. 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 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 LAS Format.

The following checks were performed. - The LiDAR data was checked against the project ground control. The technical staff confirmed the accuracy of the points during initial processing. Airborne GPS was also utilized during processing. The following methods are used to assure LiDAR 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 surface modeling - LiDAR Data - Terrascan, TerraModeler, Leica - MicroStation - ESRI - ArcInfo - ERDAS Imagine - Woolpert Proprietary software The LiDAR, meeting NMAS. The LiDAR was acquired to meet +/- 1-foot vertical accuracy (RMSE of 0.5-foot - 95% confidence level). 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 LiDAR 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, as well as 1"=1,000 scale CIR Imagery. LiDAR acquisition was flown at an approximate altitude of 7,300-feet AMT, with approximately 26,000 line miles of acquisition. The LiDAR was collected using the Leica ALS50 digital LiDAR system.
