The basis for any direct control or predictive modeling of the spatial distribution of mountain pine beetle, Dendroctonus ponderosa (Hopkins), relies heavily on the detection and delineation of red attacked trees. Historically, fixed wing aerial sketch mapping and helicopter equipped with GPS have been the two techniques most widely used in overview detection. More recently, colour aerial photography and satellite imagery have been cautiously used in this process. In 2001/2002, a preliminary study was conducted by Kim Forest Management Ltd. to examine the use of high-resolution satellite imagery (IKONOS 4-meter multispectral resolution) in the detection of mountain pine beetle attacked red trees. The preliminary study yielded promising results. However, a more detailed research study, through the funding of the FII Program, was conducted in 2003 to generate statistics that directly report on the spatial and spectral accuracy of the use of satellite imagery in red tree detection and delineation.
