      <abstract>Lake Erie Watershed 2015 Ortho/LiDAR/Hydro Project will consist the following:

•	New project – wide 1”=100’ scale color digital orthoimagery (with a 6-inch pixel resolution)
•	New project wide 0.7-meter LiDAR (average point density)
•	New project wide hydrology
•	Crest Delineation

In the Spring of 2015, imagery was acquired covering approximately 512 square miles of the Lake Erie Shoreline, PA. Imagery was collected with Leica ADS80 digital cameras and rectified using the existing LiDAR dataset. Products produced were uncompressed 4-band, 8-bit orthophotos with a 6-inch ground sample distance (GSD). The orthos are delivered as a countywide dataset, consisting of 2,500' x 2,500' GeoTIFF files. Horizontal accuracy is based upon NMAS Standards for 1"=100' scale base mapping. The file naming convention is as follows: axxxyyy; Please note that xxx and yyy represent the easting and northing coordinates (respectively) in NAD 83 (HARN) Pennsylvania State Plane North, US Survey feet. Each GeoTIFF ortho file is approximately 100 megabytes in size.  In addition to 4-band, 8-bit orthophotos with a 6-inch ground sample distance GSD product produced include countywide Multi resolution Seamless Image Database - MrSID (individual RGB - 20x and 100x; individual CIR - 20x and 100x).</abstract>
      <purpose>The Lake Erie Watershed has a goal to develop and/or update certain geospatial datasets for use by state, county, city agencies and the general public.</purpose>

        <procdesc>The Leica ADS80-SH81/82 Airborne Digital Sensor is a push-broom geometry sensor, collecting 12-bit data with 12,000 pixel swath coverage with up to a 5-centimeter spatial resolution. The sensor is capable of collecting multiple spectral bands and angles simultaneously. Leica’s ADS80 collects seven bands of imagery simultaneously: three panchromatic CCD lines capture information in the forward, nadir and backward views from the aircraft, while four multispectral lines capture data in the red, green, blue, and near color infrared band. The imagery for this task order was acquired using the Leica ADS80-SH81/82 multispectral scanner. The ADS80-SH81/82 utilizes the Leica’s IPAS20 direct positioning and orientation system that is based on airborne GPS and inertial measurement unit (IMU) technology. The IPAS20 data were reduced using Leica’s Inertial Explorer v8.5  software package. All of the source imagery was processed using the Leica XPRO (V5.2) software package. This package provides the capability to perform digital image processing, aerial triangulation, and image rectification. The strips of imagery were ortho rectified to newly collected LiDAR digtial elevation model (DEM) data. 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 (V4.5) by Inpho GmbH. The final digital orthophoto imagery (DOI) were extracted using OrthoVista.</procdesc>
