Greene County performed the generation of 2-foot contours using the new countywide LiDAR acquired during the spring of 2022 (1-meter average point density) as part of the Ohio Statewide Imagery Program. Other County Offices may also leverage the 2022 LiDAR data for the extraction of features (including land-cover, building outlines, etc.). The state of Ohio also 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. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>2022 Greene County Digital Orthoimagery Project - In the Spring of 2022 Greene County obtained new aerial LiDAR covering the entire county (+/- 416 sq. miles). The aerial LiDAR was acquired at a point density average of 1-meter with products including LAS (ground and above ground points), ESRI Raster and ASCII (both of which are ground only points). The aerial LiDAR was collected during leaf-off conditions during the spring 2022 flying season (March-April). The LiDAR is being delivered as a countywide dataset, consisting of 2,500' x 2,500' tiles (which matches the ortho tiling system). Along the perimeter of the project area, LiDAR is buffered at 100-feet beyond the countyline. Adjacent flight lines overlap by an average of 30 percent. LiDAR was collected with Leica ALS LiDAR System. The file naming convention is as follows: asxxxyyy (Ohio South Zone); Please note that xxx and yyy represent the easting and northing coordinates (respectively) in state plane feet. Each LiDAR file is approximately 10-20 megabytes in size. Ownership of the data products resides with Greene County and the state of Ohio. LiDAR and ancillary data products produced through this contract are public domain data.</SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
