Comparing nearest neighbor configurations in the prediction of species-specific diameter distributions
(Springer Nature, 2018)Key message We examine how the configurations in nearest neighbor imputation affect the performance of predicted species-specific diameter distributions. The simultaneous nearest neighbor imputation for all tree species ...Tieteelliset aikakauslehtiartikkelit

Detection of standing retention trees in boreal forests with airborne laser scanning point clouds and multispectral imagery
(2022)1. In a landscape consisting primarily of intensive forestry interspersed with some protected areas, multifunctional forestry with retention trees can play a crucial role in nature conservation. Accurate mapping of retention ...

Determining maximum entropy in 3D remote sensing height distributions and using it to improve aboveground biomass modelling via stratification
(Elsevier BV, 2021)McArthur's foliage height diversity (FHD) has been the gold standard in the determination of structural complexity of forests characterized by LiDAR vertical height profiles. It is based on Shannon's entropy index, which ...Tieteelliset aikakauslehtiartikkelit

Estimating forest stand density and structure using Bayesian individual tree detection, stochastic geometry, and distribution matching
(Elsevier BV, 2019)Errors in individual tree detection and delineation affect diameter distribution predictions based on crown attributes extracted from the detected trees. We develop a methodology for circumventing these problems. The method ...Tieteelliset aikakauslehtiartikkelit

Forest inventories for small areas using drone imagery without in-situ field measurements
(Elsevier BV, 2020)Drone applications are becoming increasingly common in the arena of forest management and forest inventories. In particular, the use of photogrammetrically derived drone-based image point clouds (DIPC) in individual tree ...Tieteelliset aikakauslehtiartikkelit

From comprehensive field inventories to remotely sensed wall-to-wall stand attribute data - a brief history of management inventories in the Nordic countries
(Canadian Science Publishing, 2021)Forest management inventories (FMIs) provide critical information, usually at the stand level, for forest management planning. A typical FMI includes (i) the delineation of the inventory area to stands by applying auxiliary ...Tieteelliset aikakauslehtiartikkelit

Optimizing the airborne laser scanning estimation of basal area larger than mean (BALM): An indicator of cohort balance in forests
(Elsevier Ltd, 2022)Airborne laser scanning (ALS) assisted basal area larger than mean (BALM) estimation measures the cohort balance in forests and provides adequate opportunities to describe forest structure. However, a problem still exists ...

Remote sensing and forest inventories in Nordic countries - roadmap for the future
(Informa UK Limited, 2018)The Nordic countries have long traditions in forest inventory and remote sensing (RS). In sample-based national forest inventories (NFIs), utilization of aerial photographs started during the 1960s, satellite images during ...Tieteelliset aikakauslehtiartikkelit

Resolution dependence in an area-based approach to forest inventory with airborne laser scanning
(Elsevier BV, 2019)In an Area Based Approach (ABA) to forest inventories using Airborne Laser Scanning (ALS) data, the sample plot size may vary or the cell size may differ from the plot size. Although this resolution mismatch may cause bias ...Tieteelliset aikakauslehtiartikkelit
