资源简介:

In the Spring of 2023, Greene County obtained new orthoimagery covering the entire county (+/- 416 sq. mi). The aerial imagery was collected during leaf-off conditions with a 6-inch pixel resolution. Imagery was collected with the Leica ADS100 Airborne Digital Sensor. Along the perimeter of the project area, ortho-imagery is buffered at 100-feet. Existing ground control and lidar data will be utilized to provide the County the most economical product. The orthos are delivered as a countywide dataset, consisting of 2,500' x 2,500' uncompressed 8-bit, 4-band color GeoTIFF files. The file naming convention is as follows: sxxxxyyyy (Ohio South Zone); Please note that xxxx and yyyy represent the easting and northing coordinates (respectively) in state plane feet. Each GeoTIFF ortho file is approximately 100 megabytes in size. Additional deliverables include countywide color and color infrared MrSID (Multi resolution Seamless Image Database) images (20x and 100x compressions), tile index provided in ESRI shapefile format, and file level (USGS parser compliantand) metadata. Ownership of the data products resides with Greene County and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data.
