Cultural heritage is very often fragile and irreplaceable presenting hidden damages covered by undamaged elements. Also, when evaluating the state of conservation of a historical structure, the first problem to face is the limited information available about the different aspects of the structure. The study of Cultural Heritage structures requires a careful analysis affecting neither the structure itself nor decorative items. In this context, non-destructive investigations play a key role and their effectiveness should be further studied in deep in relation to the specific application. Knowledge of the state of the foundations, the structural characteristics and possible damage to the elements is important and can usually be gathered from geophysical survey data. Furthermore, knowledge of the oldest structures and remains underneath the construction can also be of use in preservation studies.

GPR technique alone or combined with other geophysical surveys is the most promising method to carry out studies in Cultural Heritage structures. In fact, the scientific literature includes many works that show the effectiveness of the GPR applied in Cultural Heritage. However further experimental ant theoretical researches are necessary in order to better define the methodologies as well as the accuracy and precision of results. 

This special issue is focused to the NDT surveys in cultural heritage by using GPR. We will like to invite authors to submit papers on but not limited to the following topics: Foundation, Cavities detection, Materials and geometrical typologies of walls, Presence of cracks, Archeological surveys, Damage due to moister, GPR procedures for cultural heritage inspection, Geophysical assessment as support for maintenance detection, Practical application and examples illustrating the potential of GPR as NDT technique in the study of cultural heritage, Integrated geophysical surveys applied to Cultural Heritage, Development of software and techniques focused in cultural heritage assessment.

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. Remote Sensing 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 2700 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.
