Abstract

The basis for any direct control or predictive modeling of the spatial distribution of mountain pine beetle relies heavily on where the beetles are located at the present time, i.e., the detection and delineation of red 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. We have conducted a preliminary study on the use of high-resolution satellite imagery (IKONOS 4-meter multispectral resolution) and 1:15000 scale colour aerial photos in detection of mountain pine beetle attacked red trees. The preliminary study has yielded promising results, however, a more detailed research study examining the statistics of the spatial and spectral accuracy are necessary to quantify these findings
