Timber volume estimation based on airborne laser scanning — comparing the use of national forest inventory and forest management inventory data

Large-scale forest resource maps based on national inventory (NFI) data and airborne laser scanning may facilitate synergies between NFIs management inventories (FMIs). A comparison of models used in such a NFI-based map FMI indicate that can directly be FMIs to estimate timber volume mature spruce forests. Traditionally, have been separate activities. The increasing availability detailed provides the possibility eliminate or reduce need field sample plot measurements if their accuracy is similar. We aim 1) compare model FMI, 2) evaluate utilizing additional local plots map. Accuracies estimates using from an existing were compared at stand level. Estimates similar more accurate than FMI. addition modeling did not clearly improve map.The indicates for estimation stands, leading potentially large cost savings.
