Montesano C. Klingenberg Rasmus Astrup Sammendrag Boreal forests constitute a large portion of the global forest area, yet they are undersampled through field surveys, and only a few remotely sensed data sources provide structural information wall-to-wall throughout the boreal domain.
ArcticDEM is a collection of high-resolution 2 m space-borne stereogrammetric digital single speed skoger models DSM covering the entire land area north of 60° of latitude.
The free-availability of ArcticDEM data offers new possibilities for aboveground biomass mapping AGB across boreal forests, and thus it is necessary to evaluate the potential for these data to map AGB over alternative open-data sources i. The best model ,i.
This result highlights the synergy between 3D and multispectral data in AGB modelling. This finding highlights some of the limitations of ArcticDEM, which, despite the unprecedented spatial resolution, is highly heterogeneous due to the blending of multiple acquisitions across different years and seasons.
The synergy between the two data sources allowed for a reduction of the saturation effects typical of multispectral data while ensuring the spatial consistency in the output predictions due to the removal of artifacts and data voids present in ArcticCHM data. While the main contribution of this study is single speed skoger provide the first evidence of the best-case-scenario i.
