We collected aerial imagery from coastal wetlands along the north shore of Lake Ontario during the winter of 2014 in both 2D orthorectified and 3D stereoscopic formats for the purpose of identifying and counting muskrat houses. We compared muskrat house counts obtained from imagery to counts recorded by ground survey crews in the same wetlands during the same winter to investigate the accuracy of aerial imagery as an alternative muskrat survey method. Muskrat house count data is organized by wetland and by randomly selected 1-ha cells within each wetland. Counts obtained by ground surveys, 2D aerial orthoimagery examination by two independent observers (ortho obs 1 and 2), and 3D stereoscopic (stereo) imagery examination are recorded for each cell. This data supports Greenhorn, J.E., C.S. Sadowski, J.A. Rodgers, and J. Bowman. 2024. The use of orthoimagery and stereoscopic aerial imagery to identify muskrat (Ondatra zibethicus) houses.

        Abstract: 
        Digital orthoimagery at a resolution of 10 cm was flown in spring 2021 for the City of Waterloo, City of Kitchener, City of Cambridge, and City of Guelph. The ground conditions were leaf-off and snow and ice free.

Land Information Ontario, as well as most municipalities in southwestern Ontario and a number of other public and private sector organizations collaborated to acquire digital orthophotography for approximately 42,000 square kilometres of land in southwestern Ontario. These digital orthoimages provide full-colour aerial coverage for most of southwestern Ontario. The library has all the counties covered by SWOOP. These images were flown in April 2006 by First Base Solutions and provided to the Geospatial Centre by Land Information Ontario through the Ontario Geopatial Data Exchange in October 2006. The horizontal accuracy specification for the acquisition was set to be within 45cm of the actual location 95% of the time. Time of Capture: 2006 and 2007 Coverage: 42,000 sq km Canopy Coverage: Leaf-Off

Persons or Agencies downloading from this site are responsible for reading and abiding to information contained within the Licence provided.The Upper Thames River Conservation Authority (UTRCA) requires updated woodland/forest information as part of their core business functions and reporting process. It will be the trend that as new aerial photography (orthoimagery) is completed this information will be updated. Individual woodlands/forests can be defined based on colours and textures that are visible within the photography. This layer contains woodland areas that are greater than 0.5ha. Woodlands that are less than 20metres apart and not separated by a major road are clustered (merged) into a single polygon and are assumed to act as a single woodland. (See Unique_ID). This layer is based primarily on South Western Ontario Orthoimagery (SWOOP) 2015.
