PRIN 2015 n. 2015HJLS7E "GAMHer – Geomatics Data Acquisition and Management for Landscape and Built Heritage in a European Perspective"

The project GAMHer (Geomatics data Acquisition and Management for landscape and built Heritage in a European perspective) aims at exploding and validating Geomatics algorithms, methodologies and procedures in the framework of new European regulations, which are going to require a more extensive and productive use of digital information, as requested by the Digital Agenda for Europe as one of the seven pillars of the Europe 2020 Strategy. This has a strong connection with the Geomatics world, that has been always considered a multi-purpose discipline for a variety of applications requiring reliable and accurate digital metric information used by different specialists for scientific/industrial research and productive work. To this aim GAMHer will focus on the need of a certified accuracy for surveying and monitoring projects with photogrammetry and laser scanning technologies, when used in a multi-scale and multi-level of detail approach for landscape and built heritage documentation, conservation, and management. Indeed, the basic need of a certified metric accuracy is sometimes neglected for the availability of the new strategies for data collection and processing, that have surely improved the 3D reconstruction pipeline in terms of time and manual efforts required. However, automation comes at a cost, i.e. a lack of certified accuracy, that can result in useless and crude reconstructions without metric integrity. So, how can we overcome this limitation? GAMHer will tackle the previous issues in the framework of the new European directives (UEPPD) supporting an increasing demand of innovative methodologies to collect, process, validate and exchange digital information. Particular attention will be paid to the realization of tools and guidelines for a data acquisition/processing workflow of images and laser scans towards an accurate, reliable and accurate output for real, effective and productive work. GAMHer will investigated the advantages and limitations of actual image- and laser scan processing algorithms and procedures with both a technologyand application-driven purpose, i.e. the combined need of automation and reliability. This will improve the overall production pipeline for the generation of metric digital reconstruction, fulfilling metric requisites while preserving automation. The approach will follow a multi-scale transition that exploits GIS systems at the landscape scale, BIM technology and “point cloud-based” 3d modelling for the scale of the building, and an innovative BIM/GIS integrated approach to foster innovation, promote users’ collaboration and encourage communication between specialists and non-specialists, today all involved for a more reflective society. For this reason, the outcomes of GAMHer are not intended to be used only by a community of Geomatics specialists, but also by a multitude of users that exploit images and laser scans in their activities.
