Abstract
Airborne laser scanning (ALS) based stand level forest inventory has been used in Finlandand other Nordic countries for several years. In the Russian Federation, ALS is not extensivelyused for forest inventory purposes, despite a long history of research into the use of lasers for forestmeasurement that dates back to the 1970s. Furthermore, there is also no generally accepted ALS-basedmethodology that meets the official inventory requirements of the Russian Federation. In this paper,a method developed for Finnish forest conditions is applied to ALS-based forest inventory in thePerm region of Russia. Sparse Bayesian regression is used with ALS data, SPOT satellite imagesand field reference data to estimate five forest parameters for three species groups (pine, spruce,deciduous): total mean volume, basal area, mean tree diameter, mean tree height, and number ofstems per hectare. Parameter estimates are validated at both the plot level and stand level, and thevalidation results are compared to results published for three Finnish test areas. Overall, relative rootmean square errors (RMSE) were higher for forest parameters in the Perm region than for the Finnishsites at both the plot and stand level. At the stand level, relative RMSE generally decreased withincreasing stand size and was lower when considered overall than for individual species groups.
