2013 Bridge Creek, OR 4-Band Imagery

In March 2012, WSI (Watershed Sciences, Inc.) was contracted by Woolpert, Inc. (Woolpert) to collect Light Detection and Ranging (LiDAR) data and digital imagery in the fall of 2012 for a portion of Bridge Creek, a tributary to the John Day River, in Central Oregon. Data were collected to aid Woolpert and NOAA Fisheries in assessing ongoing channel restoration projects along the stream. This report accompanies the delivered orthophotos and documents data acquisition procedures, processing methods, and results of all accuracy assessments. The LiDAR data and documentation was delivered on November 8, 2012.

The extent of image coverage is limited to the acquired flight lines which were planned to map the shoreline and therefore may not include all areas within the bounding coordinates.

All rectified images were loaded in EarthWhere to prepare for distribution from NOAA's Digital Coast.
