Janis Ruhser, and Larry Robinson, 2019, 2018 Western Lake Erie 4-Band Mosaics - 20180824_Oregon: U.S. Geological Survey data release,


High-resolution digital aerial imagery was collected on August 23 and 24, 2018, with an 80-megapixel Phase One iXU-R 180 natural color aerial camera co-mounted with a Phase One iXU-RS 160 achromatic aerial camera. Software co-registers the simultaneously collected images to create 4-band imagery that can be displayed in either true color (RGB) or color-infrared (CIR) format. The camera system is connected to the plane's positioning and orientation system and precise metadata was generated for each exposure. This imagery was intended to be used as a base layer for object-based image analysis (OBIA) to map aquatic vegetation in western Lake Erie.

Observations and subtle shifts in vegetation communities of western Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. In 2016, broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with direct sampling in key locations, was used to establish baseline conditions for the monitoring of changes in the abundance and diversity of plant communities over time. This latest imagery dataset will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities as well as future effects.
