Abstract

This is an image mosaic of color infrared, 0.3 meter ground sample distance (GSD) , high resolution digital orthophotographs produced from aerial photos collected over the Maine coastline in the Fall of 2001 and 2002. Each pixel represents a planimetric square 0.3 meter on a side on the ground. Aerial photography was flown at 1,830 meters above mean ground level. The aerial imagery was georeferenced using 2D rectification methedology utilizing cubic convolution resampling and a minumum of 4 ground control points (GCP's). The digital orthorectified images are referenced to North American Datum 1983, UTM Zone 19, expressed in units of meters. The completed orthorectified TIFF and MG3 MrSid files represent Digital Ortho Quarter Quads (DOQQ) sized tiles. Imagery tiles provide complete coverage of the Maine Department of Marine Resources boundaries as defined by the project.

Purpose

To serve the Maine Department of Marine Resources, supplying 0.3 meter ground sample distance, map-accurate, continuous digital photographic coverage for the Maine Coastline as identified in the Maine Department of Marine Resources project.

Process Description

Aerial photography for the Maine coastline was flown at 1,830 meters above mean ground level. Imagery was captured using two cameras (Camera 1 serial number: 127756, focal length 152.731; Camera 2 serial number 144126, focal length 153.327). Color aerial photography, was acquired and processed to a positive image over the Maine Department of Marine Resources project area. The photography acquired only under conditions free from clouds and cloud shadows, smoke, haze, light streaks, snow, flooding, excessive soil moisture, during minimal shadow conditions, and with sun angle greater than 30%. The film specified was KODAK 2448 POSITIVE and KODAK 2427 POSITIVE color original film, processed to a positive image. The aerial imagery was georeferenced using 2D rectification methedology utilizing cubic convolution resampling and a minumum of 4 ground control points (GCP's).
