385 EVALUATING AIRBORNE LINEAR ARRAY TECHNOLOGY FOR OPERATIONAL FOREST INVENTORY APPLICATIONS IN BRITISH COLUMBIA Paul G. Pilon Remote Sensing Section Inventory Branch, Ministry of Forests British Columbia, CANADA ABSTRACT Canada, over the last decade, has played a leading role in the design and operation of airborne linear array sensors and the development of specific applications for forestry. These state-of-the-art imaging systems have the potential to revolutionise forest management by providing more efficient and cost-effective sources of digital information which are readily compatible with computer-based information systems. The improved radiometric, spatial and spectral performance of data from these sensors are able to provide improved feature discrimination when compared to existing optical-mechanical sensors. A review of the pertinent published literature on the use of airborne linear array data for forestry applications indicates that such data can provide improved, forest inventory mapping, regrowth monitoring, insect and disease damage assessment, inventory update and forest sampling, and can offer multispectral imaging with stereoscopic and superior cartographic accuracies. Research performed in forestry using airborne linear array data combined with recent advances in inertial navigation and global positioning systems, image analysis and GIS technology, optical data storage and artificial intelligence are at a stage where operational applications are becoming feasible. Key Words: Airborne Linear Array, Forest Inventory, MEIS, FU, CASI 1.0 INTRODUCTION Obtaining detailed and up-to-date resource information is essential for effective forest management. With the advent of computer-based information systems it is becoming increasingly important that resource data be computer compatible and be capable of being computer processed in an efficient and cost-effective manner. Airborne linear array sensors can provide detailed digital data at resolutions comparable to conventional aerial photography. The improved radiometric, spatial and spectral performance of data from these sensors provide improved feature discrimination when compared to existing optical- mechanical sensors. Canadian scientists, over the last decade, have played a leading role in the advancement of linear array technology and the development of specific applications for forestry. Research using the MEIS (Multispectral Electro-Optical Imaging Sensor) linear array imager has demonstrated a large potential of such technology for forestry applications. MEIS data has shown excellent potential for softwood species identification and discrimination (Leckie and Dombrowski, 1984), regrowth monitoring (Kneppeck and Ahem, 1987) and insect and disease damage assessment (Ahem et al., 1986; Epp and Reed, 1986; Kneppeck and Ahem, 1989). imaging areas of different forest type (Edel and Bianchi, 1986) and has been used to monitor forest stress and forest disease and damage (Miller et al., 1986; Rock et aL, 1988; Banninger, 1988). The success of research results from these sensors, to date, has been significant enough to warrant further investigation directed at developing operational forestry inventory systems which would utilize airborne linear array imager technology. 2.0 BACKGROUND Linear array imagers are a significant advancement in electro-optical sensor technology and have provided unique opportunities for the development of operational forestry applications. Electro-optical sensors have undergone three stages of evolution since the late 1960’s: First Generation single detector optical-mechanical line scanners (e.g., Landsat MSS and TM and the airborne Daedalus MSS); Second Generation multi-element linear array pushbroom line scanners (e.g., MEIS II and SPOT HRV); Third Generation two-dimensional multi-element array imaging spectrometers (e.g., the Canadian FLI and CASI systems and the American AIS). The FLI (Fluorescence Line Imager) system, although designed primarily for ocean applications, has been demonstrated over land for
