Data set contains orthophotos of an area over Long Island, NY. 100 images were orthorectified with USGS 10m Digital Elevation Models, and then mosaicked and output to 1,541 1000m by 1000m geotiff tiles with a pixel resolution of 0.5 meters.

21 photo identifiable points were selected evenly throughout the dataset and compared to a source of higher accuracy using NSSDA guidelines.; Quantitative Value: 3.6 meters, Test that produced the value: National Standard for Spatial Data Accuracy
6 images in flightline 2 (21, 23, 25, 27, 29, and 31) were not included in the AT solution because these frames consisted entirely of water. These images were warped using an affine transformation to be included in the mosaic. For 2 of the images (25 and 27) their were not enough photo- identifiable location to accurately perform the affine transformation. The transformation was still attempted to prevent a hole in the mosaic. The accuracy for these images is unknown. The affected mosaic tiles are: 6584505, 6584506, 6594504-6594507, 6604505-6604507, 6614505-6614508, 6624506-6624508, 6634506-6634508, 6644506-6644508.

Aerial Photography provided by New York State Department of State's Division of Coastal Resources. The photos were scanned at a resolution of 15 microns. Ground control points were collected primarily from NYSDS 2 ft orthophotos. Additional control points were collected from USGS DOQQs where coverage from the primary source was lacking. All elevations were derived from USGS digital elevation models. A bundle block adjustment was performed using Albany and exterior orientation parameters were calculated. Boeing/Autometric's Softplotter was used to orthorectify the photos. The images were then dodged and mosaicked using Z/I's Orthopro. No additional color-balancing was performed as the mosaic's intended purpose was the delineation of benthic habitats. The mosaic was then output into 1000m by 1000m tiles with a 0.5m pixel resolution. The naming convention uses the first 3 numbers of the UTM x coordinate followed by the first 4 numbers in the UTM y coordinate of the southwest corner.
