{ "currentVersion": 11.5, "serviceDescription": "

This dataset consists of true color aerial imagery covering the coastline and islands of the greater Acadia region, from Brooklin, ME to Jonesport, ME. Imagery was captured at 15-cm GSD resolution and used to produce 6\u201d orthorectified imagery with one-foot horizontal accuracy. Imagery collection dates were 06/26/2025, 06/27/2025, 07/26/2026, 07/27/2025, 08/12/2025, and 08/13/2025 during low tide conditions within two hours of spring tides. Additional atmospheric considerations were complied with including 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 dispatched after a precipitation-free period of at least 48 hours. The project flight plan consisted of approximately 2,670 images on 20 flight lines with 80% endlap and 30% sidelap, with sections re-collected as needed to meet image quality standards. Airborne GPS and IMU were 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, surveyed ground control points, aerotriangulation, and a digital elevation model. These aerial survey products were created under contract for the State of Maine Department of Environmental Protection. Bluesky Geospatial, subcontractor, captured the raw aerial imagery and produced the digital orthophotos and related products, while James W. Sewall, contractor, provided ground control and verified that project specifications were met.<\/span><\/p>", "serviceItemId": "7a6d477b55c64447bd1aa88db5bcbbe2", "name": "Coastal/Maine_Orthoimagery_Coastal_Acadia_2025", "description": "
