Description: <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>

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>The Greene County, OH Orthoimagery/ Lidar Project generated new topography data using newly aquired lidar. The lidar was collected and processed to meet a maximum Nominal Post Spacing (NPS) of 1 meter. Lidar data is a remotely sensed high resolution elevation data collected by an airborne platform. The lidar sensor uses a combination of laser range finding, GPS positioning, and inertial measurement technologies. The lidar systems collect data point clouds that are used to produce highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures, and vegetation. The task required the LiDAR data to be collected at a nominal pulse spacing (NPS) of 1 meter. Relative accuracy also known as "between swath" accuracy was tested through a series of well distributed flight line overlap locations. The final products include classified LAS 1.4, 2.5 feet pixel raster DEMs of the bare-earth surface in ArcGrid Format, and tile index. Tiled data was delivered in 1,250 ft x 1,250 ft tiles. Each LAS file contains lidar point information, which has been calibrated, controlled, and classified. Additional deliverables include tile index provided as ESRI shapefile, FGDC metadata files in .xml format. Ground conditions: Water at normal levels; no unusual inundation; no snow; leaf off.</SPAN></SPAN></P></DIV></DIV></DIV>
