A comparison of models used in such a NFI-based map and a FMI indicate that NFI-based maps can directly be used in FMIs to estimate timber volume of mature spruce forests.<\/p>\n<p><strong>Abstract<\/strong><\/p>\n<p align=\"justify\"><strong>Context<\/strong> Traditionally, FMIs and NFIs have been separate activities. The increasing availability of detailed NFI-based forest resource maps provides the possibility to eliminate or reduce the need of field sample plot measurements in FMIs if their accuracy is similar.<br \/>\n<strong>Aims<\/strong> We aim to (1) compare a timber volume model used in a NFI-based map and models used in a FMI, and (2) evaluate utilizing additional local sample plots in the model of the NFI-based map.<br \/>\n<strong>Methods<\/strong> Accuracies of timber volume estimates using models from an existing NFI-based map and a FMI were compared at plot and stand level.<br \/>\n<strong>Results<\/strong> Estimates from the NFI-based map were similar to or more accurate than the FMI. The addition of local plots to the modeling data did not clearly improve the model of the NFI-based map.<br \/>\n<strong>Conclusion<\/strong> The comparison indicates that NFI-based maps can directly be used in FMIs for timber volume estimation in mature spruce stands, leading to potentially large cost savings.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nRemote sensing; Lidar; Mixed model; Forest resource map; Large-scale mapping<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-021-01061-4'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nRahlf, J., Hauglin, M., Astrup, R. et al.
