Land use | ||
~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
In i-Tree Eco Land Use (LU) is defined as the land use type in which a tree is located. In i-Tree Eco, there are 13 default land use classes defined (see `Table 1 <tables.rst>`_). | ||
The land resource map FKB-AR5 (Ahlstrøm et al. 2019, Kartverket, 2023b) and the land use map from SSB (2022) are combined, and the different land use classes are translated to the Land Use classes defined in i-Tree Eco `Table 2 <tables.rst>`_ and `Table 3 <tables.rst>`_. | ||

Municipal Tree Inventory | ||
Municipal Tree Database | ||
~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
The municipalities within the Trekroner-project each provided a tree inventory database. | ||
The tree inventory databases contain information about the trees in the municipality, | ||
such as tree species, tree height, tree diameter, and tree location. | ||
The tree inventory databases were cleaned and standardized to ensure that the data could be used in the i-Tree Eco analysis. | ||
