      <abstract>Logan County, OH - 2019 1.5" and 3" Orthos, 0.7-meter LiDAR project consists of the following: New countywide, 8-bit, 4-band (R,G,B,NIR) stacked “Leaf - Off” orthoimagery with a 3-inch pixel resolution, new area-wide 8-bit, 4-band (R,G,B,NIR) stacked "leaf-off" orthoimagery with a 1.5-inch pixel resolution, and countywide 0.7-meter LiDAR.  New ground control will be collected and DEM data will be derived from the new lidar to provide the County the most current, up to date product.  
        In the Spring of 2019, Logan County obtained new orthoimagery covering the entire county (+/- 467 sq. mi). The aerial imagery was collected during leaf-off conditions with a 3-inch pixel resolution. Imagery was collected with the DMC-III Airborne Digital Frame Camera. Along the perimeter of the project area, ortho-imagery is buffered at 100-feet. Existing ground control, along with new, will be utilized along with existing DEM data to provide the most economical product. The orthos are delivered as a countywide dataset, consisting of 1,250' x 1,250' uncompressed 8-bit, 4-band color GeoTIFF files. The file naming convention is as follows: bnxxxyyy (Ohio North Zone); Please note that xxx and yyy 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), FGDC compliant metadata per file, tile index provided in ESRI shapefile format. Ownership of the data products resides with Logan County and the state of Ohio. Orthoimagery and ancillary data products produced through this contract are public domain data.

      <purpose>Logan County, OH has a goal to develop and/or update their existing orthoimagery and lidar geospatial dataset for use by city agencies, other levels of government, academia, and the general public, and to provide these datasets for inclusion to OGRIP.  OGRIP is a State of Ohio resource for geographic information technology users.  </purpose>

        <procdesc>The imagery for this task order was acquired using the DMC-III Airborne Digital Frame Camera. All of the source imagery were initially processed in Leica’s FramePro software for image frame generation, and then final processed using the ImageStation Automatic Traiangulation (ISAT) software package. This package provides the capability to perform digital image processing, aerial triangulation, and image rectification. The imagery were ortho rectified to LiDAR digtial elevation model (DEM) data. </procdesc>

        <procdesc>The individual rectified strips of ortho rectified imagery were then mosaicked together to form a seamless imagery database over the entire task order area using the OrthoVista software by Inpho GmbH. The final digital orthophoto imagery (DOI) were extracted using OrthoVista. Final orthophoto non-overlapping tiles were produced in GeoTIFF format (with World files) using a cell size of 3-inch and a tile size of 1,250’ x 1,250’.</procdesc>
