Shiny-lmfor

The purpose on this tool is to provide an easy application for estimating relationship between tree breast height diameter (DBH) and top height with the help of ‘lmfor’ R-package. This package provides 20 different tree height models.

The use of the tools requires that there are some sample plot data available for the estimation. Each sample plot should preferably contain at least one height sample tree.

The input data should be in a CSV format file, and it should contain the following fields: (cluster,) plot, tree_dbh, tree_height. Field ‘cluster’ is optional if the sample plots are grouped into clusters.

After uploading the data, the program shows a DBH-Height scatterplot. In this chart a small hover box shows tree_dbh, tree_height and plot_id (which is the combination of “cluster” and “plot” codes).
