A WEBGIS FOR THE KNOWLEDGE AND CONSERVATION OF THE HISTORICAL BUILDINGS IN SARDINIA (ITALY)

Vacca, G.; Fiorino, D. R.; Pili, D.

The presented work is part of the research project, titled "Tecniche murarie tradizionali: conoscenza per la conservazione ed il miglioramento prestazionale" (Traditional building techniques: from knowledge to conservation and performance improvement). This research project has the purpose of studying the building techniques of the 13 th–18 th centuries in the Sardinia Region (Italy) for their knowledge, conservation, and promotion. The end purpose of the entire study is to improve the performance of the examined structures. In particular, the task of the authors within the research project was to build a WebGIS to manage the data collected during the examination and study phases. This infrastructure was entirely built using Open Source software.

The work consisted of designing a database built in PostgreSQL and its spatial extension PostGIS, which allows storing and managing feature geometries and spatial data. The data input is performed via a form built in HTML and PHP. The HTML part is based on Bootstrap, an open tools library for websites and web applications. The implementation of this template used both PHP and Javascript code. The PHP code manages the reading and writing of data to the database, using embedded SQL queries. The database is published on the Internet as a WebGIS built using the Leaflet Javascript open libraries, which allows creating map sites with background maps and navigation, input and query tools. This too uses an interaction of HTML, Javascript, PHP and SQL code. The Database can be accessed in QGIS via a PostgreSQL connection.

As of today, we surveyed and archived more than 300 buildings, belonging to three main macro categories: fortification architectures, religious architectures, residential architectures.
