INTEGRATED TECHNOLOGIES FOR SURVEYING ARTEFACTS DAMAGED BY EARTHQUAKES. APPLICATION OF ALLIN- ONE LIDAR TECHNIQUES IN THE CITY OF L'AQUILA

Abstract. The purpose of this work is to demonstrate how, in post-earthquake intervention scenarios, the latest "all-in-one" laser technologies employed beyond their usual applications and integrated in more traditional survey methods, can define a comprehensive and original approach method in response to surveying issues, safety of the artefacts, speed and low cost of surveys, quality of data and of the models provided for damage assessments and any required action. The case study of L'Aquila is therefore significant. The red area has essentially two types of buildings: monuments and historical buildings characterised by compact urban centres. Here we document the convent of the Blessed Antonia and the Antenucci Block, as case studies and synthesis of the two types and ideal laboratories to test the chosen method. In the first case, we document the project on a building that is yet to be secured and that therefore presents delicate issues in terms of survey speed and completeness, also in relation to the precious decorations that it holds. In the other case, we document the survey of the typical block in Aquila, already secured which, given the size and complexity, requires an integrated approach, more complex and more time-consuming of methods of analysis.
