Description

This digital orthomosaic covers the entire Grand River watershed. The watershed extends from the headwaters of the Grand River near Luther Marsh Reservoir to the mouth of the Grand River at Port Maitland on Lake Erie. Aerial photography was flown between April 4th-30th, 2000, and was provided to the Library by the Grand River Conservation Authority (GRCA) in September 2004. The pixel resolution of the orthomosaic is 30 cm.
