| Aerial sketchmapping is a simple, low cost remote sensing method used for detection and mapping of forest damage caused by biotic agents (insects, pathogens and other pests) and abiotic agents (wind, fire, storms, hurricane, ice storms) in North America. This method was introduced to Brazil in 2001/2002 via a USDA Forest Service/EMBRAPA technical exchange program, which included demonstration flights, a feasibility study, workshops, production of satellite maps, observer training and operational flights, primarily for assessment of damage caused by European wood wasp (Sirex noctilio), monkeys (Cebus nigritus), armillaria root disease (Armillaria spp.), and other damaging agents in pine plantations in Southern Brazil. New applications have been investigated... |
