ETM+ satellite images have traditionally been used to provide auxiliary data for large-area forest inventories. One of their advantages is their large geographic coverage. Their disadvantages include the medium resolution and lack of 3D information. These disadvantages can be compensated through the Airborne Laser Scanning (ALS) data in combination with aerial images. Finnish Forestry Centres use Airborne Laser Scanning (ALS) data in combination with aerial images for small-scale forest inventories in the management planning of privately-owned forests. For different forest management tasks in different land-class areas, different sets of ALS features are used. The goal of this study was to investigate the performance of ALS data in combination with satellite optical data for large-area forest stratification-based inventories in order to increase the estimation accuracy. Ellipsoid stratification was used. It was found that with an increasing number of strata for stratification, the standard error for the total stem volume was found to decrease and stabilize.
