摘要：Timeliness and up-to-date information on the status of different landscape components are a key issue for decision makers, land planners and farmers involved in the adoption of remedial measures to ameliorate land degradation and increase profitability in agricultural areas. Rapid access to these data can be achieved via an information management system capable of integrating various data types for assessment and monitoring. But, to be useful to farmers and land planners, the system should offer simple, easy to use, image products for monitoring crop and soil conditions, the impact of phenomena such as hail or frost, weeds, soil variability and the effect of fertilisers or spray applications at a paddock level. Accordingly, this paper examines the potential of airborne videography as a remote sensing tool in a project aimed to develop a rapid and cost-effective system for assessing and monitoring the conditions of crops, native forest and re- vegetated areas in the agricultural region of Western Australia. This implies a close examination of existing techniques for low cost/high resolution data capture, as well as identifying value-added products easy to be used and understood by farmers and land planners interested to know where and why field variations occur in their paddocks. Mapping the occurrence of such variations would enable farmers to identify the causes of variability and to decide on appropriate management practices to correct the problem, if it is economically feasible
