LAND-SUITE V1.0: a suite of tools for statistically based landslide susceptibility zonation
Geoscientific Model Development 15(14) : 5651-5666 (2022)
Abstract
In the past 50 years, a large variety of statisti-
cally based models and methods for landslide susceptibility
mapping and zonation have been proposed in the literature.
The methods, which are applicable to a large range of spa-
tial scales, use a large variety of input thematic data, differ-
ent model combinations, and several approaches to evaluate
the models’ performance. Despite the numerous applications
available in the literature, a standard approach for suscepti-
bility modeling and zonation is still missing.
The literature search revealed that several software pro-
gram and tools are available to evaluate regional slope
stability using physically based analysis, but only a few
use statistically based approaches. Among them, LAND-SE
(LANDslide Susceptibility Evaluation) provides the possi-
bility to perform and combine different statistical suscepti-
bility models and to evaluate their performances and asso-
ciated uncertainties. This paper describes the structure and
the functionalities of LAND-SUITE, a suite of tools for sta-
tistically based landslide susceptibility modeling which in-
tegrates LAND-SE. LAND-SUITE completes and extends
LAND-SE, adding functionalities to (i) facilitate input data
preparation, (ii) perform preliminary and exploratory analy-
sis of the available data, and (iii) test different combinations
of variables and select the optimal thematic/explanatory set.
LAND-SUITE provides a tool to assist the user during the
data preparatory phase and to perform diversified statistically
based landslide susceptibility applications.
