Nearly 4800 digital still photographs were taken between Cape Sabine and Milne Point, July 16-19, 2009. This ArcGIS shape file includes the position of the aircraft and the time each photo was taken. Purpose: To provide an easily accessible overview of the coastal morphology and character of the north Alaska coast.

Logical_Consistency_Report: Because of variable aircraft altitude and distance from the shoreline, along with variable shooting prarmeters, the photgraphs do not show a consistant image width. Completeness_Report: Some gaps in photography exist due to fog banks or rain, and only partial coverage of the river delta areas was collected. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Positional information reflects the position of the aircraft and was collected using a handheld, WAAS enabled GSP unit, recording at 2 Hz. DGPS (WAAS) accuracy for position is less than 3 meters. (From Garmin GPSMAP 76C/76CS Specifications, M01-10108-00, Rev0304, ). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The aircraft typically flew at about 500 feet elevation and approximately 1000 feet offshore. Barometric altimeter features 10 feet accuracy with proper calibration with a resolution of 1 foot. (From Garmin GPSMAP 76C/76CS Specifications, M01-10108-00, Rev0304, ). Lineage: Process_Step: Process_Description: Photos were collected from a Cessna 185 Skywagon II floatplane, typically at an altitude of about 500 feet (152 meters) and approximately 1000 feet (305 meters) offshore. The primary camera was a 10.2-megapixel Nikon D200 digital camera, with a 18-200 mm zoom lens (DSC_iiii.jpg filename format, where "iiii" is an image counter). In general, photographs were taken using the largest field of view. However, the photographer could also zoom the lens to collect more detailed photos of features of interest. Because of variable aircraft altitude and distance from the shoreline, along with variable shooting parameters, the photographs do not show a consistent image width. A Garmin GPSmap 76CSX (WAAS enabled) handheld global positioning system (GPS) unit recorded the position of the aircraft every 2 seconds. All the imagery was georeferenced to the aircraft position at the time the photo was taken, annotated with position and time information, resampled (to 2000 x 1339 pixels), using software and hardware developed by Red Hen Systems (http://www.redhensystems.com/).
