Raw data, first acquired by several and integrated geomatic procedures and subsequently processed so as to achieve a 3D geometrical model, are the basis for conservation and preventive maintenance of the Cultural Heritage; furthermore, they also allow for the employment of the BIM, Building Information Modeling methodology.

Terrestrial laser-scanning (TLS) is well suited to surveying the geometry of monumental complexes, often realised with highly irregular materials and forms. This paper addresses various issues related to the acquisition of point clouds via TLS and their elaboration aimed at developing structural models of masonry vaults. This structural system, whi...

The sites identified as "Industrial architecture" are a collection of structures, having a peculiar identity, which can still be used as a contemporary resource, worth being re-interpreted by means of urban projects of integrated and sustainable transformation urban font. In particular it is necessary to reactivate or create new processes, both pro...

The paper addresses some issues related to the acquisition of points clouds by Terrestrial Laser-Scanning, TLS and their elaboration with the aim to create structural models of masonry vaults. This structural system, existing in several artifacts and historical buildings, presents the advantage of having a good static and functional behavior, reduc...

The paper describes a simplified GIS approach, for landslides risk assessment in the Province of Bergamo, developed for a GIS degree thesis at the faculty of Engineering of the University of Bergamo. The subject has been and still is largely studied by many researchers with the aid of rigorous mathematical/statistical analysis tools. This work foll...

This paper describes the results of a study developed, with a GIS approach, at the University of Bergamo, about snow avalanche zoning and risk assessment in the Province of Bergamo. The adoption of a simplified estimation model, presented here, nonetheless allowed achieving results in good accordance with those provided by previous, more rigorous s...

Terrestrial laser scanners are contact-free measuring devices which can collect dense point-clouds of objects. A measurement is only usable if the return energy lies above a certain threshold. When planning a laser-scanning survey the subsequent positions of the scanner must be carefully chosen such that sufficient overlap of the pointclouds is ens...

A set of images are needed in photo texturing for describing material, color or decay information to be superimposed on point or meshed models. In Bergamo, the 14th century Church of St. Maria Maggiore is of great significance for the local community. This sandstone monument has been object of documentation analysis by the Geo-technology Laboratory...

Image-based modelling is still the most widely used approach in building documentation and 3D investigations, but panoramic camera laser scanners are gaining in importance. They offer large fields of view, good accuracy and direct photo-texturing. The authors have tested the information content and performance of such systems in 3D modelling of St...

In Lombardy (Italy) one has started a project on risk-assessment of buildings of historical-architectural importance. For this purpose a Building Information System (BIS) has been created, based on archived and surveyed data. Essentially a multi-sensor approach has been applied to archive the inside and the outside of the monument. The primary tech...

The ability to measure surfaces and objects in their full spatial dimensions is becoming increasingly important for building investigation. Non-contact measurement active scanning techniques, such as laser scanning, are of rapidly increasing importance for the acquisition of three-dimensional models of objects, possibly at the cost of the more trad...

Processing the wide variety of geo-data collected by surveying, photogrammetry and remote sensing currently requires multimedia systems and data accessible over the World Wide Web. This development induces the need for standardisation of both vector and raster data formats. The authors consider standardisation issues related to transferring 2D and...

BA.M.BA. is a new software for GPS data processing. It works following a multibase approach to process observations collected in static mode. The structure of the program is modular, basically constituted by three parts devoted to perform the following operations: preprocessing first processing final processing

This work is an approach to the solution of inverse cartographic problems, arising when we want to compare or to merge two maps, one of known mathematical form and one which is not well known, even if we assume they are of the same kind, for instance both conformal or both equivalent. So we tried to estimate the unknown transformation function star...

Urban landscape complexity points out the increasing importance of a detailed geometric knowledge, mostly for buildings with a historical and architectural value. So, an accurate building survey is needed, both for morphologic and dimensional documentations and for structural and material aspects. A study for monitoring and analyzing building struc...
