Special Issue Information
Dear Colleagues,
In the maintenance of large infrastructure, including dams, bridges, and tunnels, monitoring of deformations plays a key role in maintaining safety conditions and for mitigating any consequences due to ageing factors and possible structural failure. This concern is, today, even more important than in the past due to the relevance of such infrastructure in our society, and the serious follow up of collapse or limitation in their uses. Considering the complexity that large infrastructure might feature, monitoring approaches call for the use of multiple sensors organized in networks. Signals recorded by different instruments can be conveyed to a control unit that can filter and evaluate all the outputs to feed numerical models able to predict the future behavior of the structure. On the sensor side, several new technologies have been developed and successfully applied in recent years. Contact sensors may yield continuous observations at key points of a structure, with the chance of also being embedded inside structural elements, such as in the case of fiber optic sensors. In this category, robotic geodetic instruments and GNSS sensors can provide 3D absolute displacements of a structure body. On the other hand, areal-based deformation measurement techniques have been developed to depict a general overview of the deformation patterns on the basis of terrestrial remote sensors, such as laser scanning and ground-based interferometric SAR systems. In addition, SAR observations from satellites are becoming more and more reliable for wide area and long-term deformation monitoring. This Special Issue is aimed at providing the readers an up-to-date overview of the methodologies, sensors, and processing techniques adopted for monitoring the deformation of large infrastructures.
The topics include, but are not limited, to:
Sensor networks for large infrastructures monitoring;
GNSS techniques for monitoring 3D displacements, including the use of low-cost sensors;
Application of high-resolution and short return-time SAR satellite systems;
Integration between observation and structural modeling (data assimilation);
Areal-based deformation monitoring techniques;
Application of terrestrial remote sensors;
Spaceborne InSAR techniques;
Image-based and photogrammetric techniques;
Technologies and sensors developed for a specific category of infrastructures.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
Benefits of Publishing in a Special Issue
