Low Tide orthophotos Casco Bay 2013

Tags
Digital Imagery, Orthophotography, Planning, True Color, NIR, 4 Band GeoTIFF, 3 Band MG3 MrSids


Summary

To serve Casco Bay Estuary Partnership, supplying 0.15 meter ground sample distance, map-accurate, continuous digital photographic coverage of Casco Bay in Maine as identified in the Casco Bay, ME project of 2013.

Description

This is an image mosaic of 4 band, 0.15 meter ground sample distance (GSD), high resolution digital orthophotographs produced from aerial photos collected over the Casco Bay area of Maine on August 11 and 12, 2013. Each pixel represents a planimetric square 0.15 meter on a side on the ground. Aerial photography was flown at approximately 453 meters above mean ground level (mean ground level is approximately 8 meters). Source elevation data is 1/3 arc second data acquired from USGS. The digital orthorectified images are referenced to North American Datum 1983, UTM Zone 19 expressed in units of meters. The completed 4 band orthorectified Geotiff files represent a custom developed 1500 meter x 1500 meter grid approved by Casco Bay Estuary Partnership. 3 band tiled MG3 MrSid files were also created. Imagery tiles provide complete coverage of the Casco Bay site in Maine.

Description Aerial photography for Casco Bay site in Maine was flown at approximately 453 meters above mean ground level (mean ground level is approximately 8 meters). Imagery was captured using one DMC1 camera (serial number DMC131). Color aerial photography flown in a generally northeast-southwest direction, controlled by Airborne Global Positioning System (GPS). Inertial Measurement Unit (IMU) data was acquired and digitally processed over the Casco Bay project area. The photography was acquired only under conditions that minimize clouds and cloud shadows, smoke, haze, light streaks, snow, flooding, excessive soil moisture and during optimal shadow conditions. Casco Bay Estuary Partnership communicated the appropriate flight window to capture the imagery. Adequate stereo coverage over the project area was required with a minimum overlap of 60% forward and 30% side.
