Testing Large-scale Photography to Sample Plots for Forest Inventory in Mixed Hardwood Forests of the Great Lakes-St. Lawrence Region of Ontario

Large-scale photography (LSP) may be a useful tool to measure traditional and non-traditional forest attributes. This paper evaluates an LSP system for plot sampling in Great Lakes-St. Lawrence forests by comparing the utility of leaf-off and leaf-on imagery, assessing targeting accuracy, and comparing ground and LSP values for some commonly measured inventory, research and monitoring variables, and for less commonly measured variables.
