Tools
-
1
Forest Data Checker
Import tree and plot tables, map the columns, find format errors and suspect measurements; record every fix with a reason and approve the data.
-
2
Plot & Stand Metrics
From approved data, per plot and period: stems and basal area per hectare, mean diameters, diameter classes and species composition; between-plot summary and design-based forest estimate.
-
3
Model Evaluation
Bias, MAE, RMSE and prediction R² from observed and predicted values; observed–predicted and residual plots, performance tables by group.
-
4
Diameter Distribution Lab
Weibull version: maximum likelihood and moment estimation from tree diameters, three-parameter form with a fixed location, class frequencies with tails, per-plot fits, curve explorer. Other distributions in later versions.

Relative Ranking
Relative ranks per criterion and overall from a goodness-of-fit table (R², FI, RMSE, MAE, Bias, AIC, BIC…); radar chart of the best and worst models.
