摘要: Ten ERS image pairs from the tandem period have been analyzed for two test sites in Sweden and results compared with based on 24 previously studied sites. All four represent boreal forests include 338 forest stands stem volumes up to 539 m 3 /ha. With optimal environmental conditions (sub zero temperature, dry snow layer, moderate breeze) large homogeneous relative RMSE is of order 20% while less 30%. The RMSEr increasing number small or low volume. No saturation volume found. consistency coherence observations a certain stand can be used identify potential giving accurate estimates A baseline 200-250 favorable.
