The Unmanned Aerial System (UAS) is widely used in the photogrammetric surveys both of structures and of small areas. Geomatics focuses the attention on the metric quality of the final products of the survey, creating several 3D modelling applications from UAS images. As widely known, the quality of results derives from the quality of images...

A useful contribution to atmosphere monitoring may be provided by the analysis of GNSS (Global Navigation Satellite System) signals. The authors have identified a procedure to monitor in space and time the Precipitable Water Vapor (PWV) content on regionally extended and orographically complex area. The starting point of the procedure is the...

The conservation of Cultural Heritage depends on the availability of means and resources and, consequently, on the possibility to make effective operations of data acquisition. In facts, on the one hand the creation of data repositories allows the description of the present state-of-art, in order to preserve the testimonial value and to permit...

An optimized planning and realization of the survey, coupled with well thought-out processing, allows obtaining good quality results, while guaranteeing a reasonable use of resources and time. It represents a benefit for both operators and end-users. The former can save time and acquire smaller datasets to process, while the latter can invest...

The task of conservation and management of cultural heritage is quite central in Italy, which lists a high number of beautiful architectures. A quick and precise survey may be requested in case of calamity. In the present paper, the most commonly used survey techniques are discussed, focusing on their applications for the conservation of the...

Orthophotos are one of the most common and typical products of a photogrammetric post-processing and, since the diffusion of specific software, their generation and usage have become even more widespread. In spite of it, some issues remain on the accuracy of orthophoto reconstruction, which is often downgraded by the introduction of meshes and...

The paper presents the geomatic survey campaign carried out in the Domus V of Pompeii Archaeological site, the photogrammetric processing of the collected images and the following fruition of the deriving products deploying open-source software. Among all the produced results, the orthophotos of the vertical walls of one of the Domus V rooms...

Innovative researches developed by the Authors are described in order to demonstrate the usefulness of GIS (Geographic Information System) in support of geotechnical analysis, with particular reference to risk zoning and mitigation and to the monitoring of slopes. A multivariate statistical procedure for the estimation of landslide...
