“…However, it is still common to perform data-acquisition campaigns based on paper datasheets that are later transferred and managed on informatics platforms. Some examples of this approach are given in the Rapid Seismic Vulnerability Assessment developed by Nanda et al [7], the survey form for masonry buildings of Guiliani [8], the model of the Bihar State Disaster Management Authority (India) [9] or the CARTIS datasheet for the typological characterisation towards seismic risk [10]. There are territorial-scale applications that have used similar approaches for assessing other types of vulnerabilities, such as the implementation performed by Salvati et al [11] for assessing geo-hydrological hazards.…”

The characterisation of the seismic vulnerability of historical constructions represents a complex problem in which the typological variability, the difficulty of performing reliable large-scale assessments and dealing with a large database all play a role. Nevertheless, reducing the uncertainty regarding the structural vulnerability of the existing building stock (mostly for small and/or isolated human settlements) is key for risk assessment and management. The present work proposes a novel approach based on the integration of a series of open-source tools for assembling a vulnerability-oriented database that is linked to a series of external services for increasing its capabilities. The database was implemented in a Geographical Information System (GIS) environment and contains the survey of a seismic vulnerability index for masonry constructions based on an adapted version of the GNDT-II approach. A customised Python-based software for reading, managing and editing the database is herein presented. This program allows the execution of the most typical operations with no assistance from the GIS environment, facilitating user interaction. Furthermore, the calculations regarding the vulnerability index and levels of damage have been implemented in this program. Alternatives for distributing the database are implemented and discussed, such as cloud-based distribution and the use of the Transactional Web Feature Service (WFS-T) protocol for its virtual publishing. The entire framework herein presented is a replicable and feasible workflow that can be set even with reduced infrastructure, allowing a progressive enlargement.
