Mobile Laser Scanning in Forest Inventories: Testing the Impact of Point Cloud Density on Tree Parameter Estimation [PDF]

Sensors
Forest inventories are essential for monitoring and managing forest ecosystems, relying on accurate measurements of tree attributes such as tree detection, Diameter at Breast Height (DBH), and Tree Height (TH). Nowadays, advances in LiDAR technology have

Using Fay–Herriot Models and Variable Radius Plot Data to Develop a Stand-Level Inventory and Update a Prior Inventory in the Western Cascades, OR, United States

Frontiers in Forests and Global Change, 2021
Stands are the primary unit for tactical and operational forest planning. Forest managers can use remote-sensing-based forest inventories to precisely estimate attributes of interest at the stand scale. However, remote-sensing-based inventories typically

Main principles for state forest inventory organization and implementation [PDF]

Вопросы лесной науки, 2019
First national forest inventories was done in 20-30th of last century in Scandinavian countries Norway (1919-1930), Sweden (1923-1929) and Finland (1921-1929). In Russia forest inventory by sampling method for the first time was done at the same time but

Reuse of field data in ALS-assisted forest inventory

Silva Fennica, 2020
Forest inventories assisted by wall-to-wall airborne laser scanning (ALS), have become common practice in many countries. One major cost component in these inventories is the measurement of field sample plots used for constructing models relating ...

Design considerations for tropical forest inventories

Pesquisa Florestal Brasileira, 2013
Forests contribute substantially to maintaining the global greenhouse gas balance, primarily because among the five economic sectors identified by the United Nations Framework Convention on Climate Change, only the forestry sector has the potential to ...

Mapping global forest age from forest inventories, biomass and climate data [PDF]

Earth System Science Data, 2021
Forest age can determine the capacity of a forest to uptake carbon from the atmosphere. However, a lack of global diagnostics that reflect the forest stage and associated disturbance regimes hampers the quantification of age-related differences in forest

Consistency of stand density estimates and their variability in forest inventories in Slovenia

Acta Silvae et Ligni, 2014
The national estimates of forest resources in Slovenia are based on data aggregation from forest inventories conducted in forest management units of Slovenia Forest Service (SFS) and on the parallel forest inventory established within the Forest and ...
