Ayres Associates provided the Grand Forks – East Grand Forks Metropolitan Planning Organization with digital, color orthoimagery services in 2021. The aerial imagery was collected on April 10 using a Leica DMC III sensor mounted in a fixed-wing aircraft equipped with Inertial Measurment Unit (IMU) and Airborne GPS. Aerial imagery was collected to support 0.25 foot ground sample distance (GSD) orthoimagery to meet the National Mapping Accuracy Standard (NMAS) for 1"=50' scale mapping. The horizontal accuracy meets or exceeds NMAS requirements, stating that 90% of all test points be within 1/30th of an inch at mapping scale. Resultant orthoimagery was rectified to a DEM surface created from new LiDAR data acquired in 2021. Orthoimagery was delivered in PLSS quarter section GeoTIFF, ECW, and MrSID tiles and a project-wide ECW and MrSID mosaic. Additional Information: The Grand Forks – East Grand Forks Metropolitan Planning Organization is a certified planning entity in the State of North Dakota and Minnesota and is comprised of the cities of Grand Forks and East Grand Forks. The purpose of the MPO is to provide a forum for public officials, citizens, and other interested groups to establish policies and plans for effectively addressing various metropolitan transportation issues. The MPO has a planning process that supports metropolitan community development and social goals. These plans and programs shall lead to the development of an integrated, inter-modal metropolitan transportation system that facilitates the efficient, economic movement of people and goods.
