计算机分类的陆地卫星地图进行了比较，最近在北方缅因州的林地的传统库存。在196，000公顷的测绘面积上，通过对大地卫星数据进行监督分类和根据航空照片判读、与预测成比例的概率、实地取样和标准森林测量程序编制的标准清单获得的软木、混合木和硬木森林面积估计数在5%以内。大地卫星地图的费用估计为每公顷0.065美元。得出的结论是，卫星技术值得开发用于森林清查，尽管这些技术尚未完善到足以纳入目前的实际清查。
Computer classified Landsat maps are compared with a recent conventional inventory of forest lands in northern Maine. Over the 196,000 hectare area mapped, estimates of the areas of softwood, mixed wood and hardwood forest obtained by a supervised classification of the Landsat data and a standard inventory based on aerial photointerpretation, probability proportional to prediction, field sampling and a standard forest measurement program are found to agree to within 5%. The cost of the Landsat maps is estimated to be $0.065/hectare. It is concluded that satellite techniques are worth developing for forest inventories, although they are not yet refined enough to be incorporated into current practical inventories.
