Service Description:

This dataset consists of true color aerial imagery of the Pisctaqua coastal region between York, ME and Cape Elizabeth, ME and was captured at 14.5-cm GSD and used to produce high resolution 6” orthorectified imagery with a one-foot accuracy. Imagery was collected on June 28th and 29th, 2021, during low tide conditions and within two hours of spring tides. Additional atmospheric considerations that were considered before each lift included flying in a sun angle between 25 degrees and 50 degrees, no more than 10% cloud cover, and less than 10 knots of a maximum predicted wind velocity. Additionally, flights were only be dispatched after a precipitation-free period of at least 48 hours. The project area consisted of approximately 400 images on approximately 7 flight lines with 60% forelap and 30% sidelap. Airborne GPS and IMU were be utilized during the acquisition to improve the aerotriangulation solution. Raw imagery was acquired using the Vexcel Eagle 80-mm Mark 3 mounted on a fixed wing aircraft and flown at an elevation of approximately 9,500 feet. Digital ortho-rectified imagery was created using the raw digital aerial imagery, ground control, aerotriangulation, and a digital elevation model. Existing State of Maine ground control was utilized in the aerotriangulation solution for this project. These aerial survey products were under contract for the State of Maine Department of Environmental Protection. Bluesky Geospatial captured the raw aerial imagery and James W. Sewall processed the raw imagery to develop the aerotriangulation solution and to create digital orthophotos and related products. Normandeau Associates served as Aerial Survey Coordinator to verify that project specifications were met.
