The purpose of this publication is to provide a spatial reference for oblique aerial photographs taken along the Port Heiden shoreline in August 2013. The oblique aerial imagery is intended to serve as a photographic reference of coastal features and conditions at the time of collection.

The accuracies of the photo points are dependent upon the horizontal positional accuracy of the handheld GPS unit and camera and GPS clock synchronization. The clocks of both the camera and GPS were synchronized in order to link the camera's photographs with the spatial location provided by the GPS.
Accuracies of photo points are dependent on the handheld GPS units used to track the helicopter's position. According to the Garmin manual, typical horizontal errors for the Dakota 20 are less than 10 m.
Oblique aerial photographs are provided for the section of Port Heiden shoreline from 7 miles (11 km) northeast of Reindeer Creek to 10 miles (16 km) southwest of Strogonof Point. Photographs were taken approximately every 30 to 100 meters from a flying height of 500 to 1,500 feet above ground level (AGL). A continuous shooting mode was used, resulting in gaps in image collection that are greater than 100 meters during periods when the camera was auto-focusing. Any altitude values accessed under the image properties of the geotagged photographs have not been verified and therefore should not be used.
No topologic relationships are present in the data. The following logical consistency test was performed: each photograph was visually checked against its corresponding geospatial location on orthorectified 2002 aerial imagery and 1998 Landsat satellite imagery. Any altitude values accessed under the image properties of the geotagged photographs have not been verified and therefore should not be used.
