The validation tool compares uploaded data with data of LVISA as scatter plot of two selected features for a selected set of tree classes, families or species. The data is displayed as a collection of points, each having the value of the selected statistical method concerning the features of the trees.
Additionally, the similarity in feature characteristic of each external tree with LVISA is calculated and represented by the nearest tree (minimum Euclidean Distance) and the amount of trees within the selected search radius and features.
