La tecnica WofE, utilizzata anche nel Progetto Permanet, prevede l’acquisizione di una serie di informazioni spazializzate e standardizzate. Il modello si basa su metodologia quantitativa per combinare “evidenza“ a supporto dell’ipotesi (ossia la distribuzione dell’evento) e si fonda su una serie di temi (es. uso del suolo, litologia) a cui viene dato un peso rispetto alla probabilità di accadimento. I parametri su cui si basa il modello consistono in una serie di dati d’ingresso e un set di fenomeni avvenuti presenti in un database storico (training points). I parametri gestiti sono vincolati alla loro disponibilità e ricampionati per ottenere una risoluzione standard

Abstract
The WofE technique, also used by the PermaNET Project, is based on the acquisition of spatial and standardised information. This model is aimed at collecting evidence supporting the hypothesis (the event distribution) through a quantitative method and is based on a number of elements (such as land use, lithology) that acquire a certain weight in relation to their likeliness of occurrence. The model parameters are a series of input data and of occurred events inserted into a historical database (training points). The use of these pa- rameters depends on their availability; they are then re-sampled in order to obtain a standard resolution.File | Dimensione | Formato | |
