Dear Colleagues,

Underwater photogrammetric surveying through images acquired by divers and unmanned underwater vehicle has been used for many applications in the oil industry, archaeology, and biology. The accuracy needed for the applications has changed from some cm level to high-accuracy level requirements (less than 1 cm accuracy), such as for multitemporal analysis for change detection purposes, depending on the camera settings used and the distance to the imaged object.

We have assisted toward a significant evolution of underwater cases and dome ports and camera characteristics.

Particularly useful for modern underwater photogrammetry has been the utilization of structure-from-motion (SfM) photogrammetry. Structure-from-motion photogrammetry and underwater imagery allow three-dimensional quantification of submersed structures characteristic at patch scale and structural complexity.

There has also been significant improvement in integrated applications using photogrammetry, acoustic surveying, laser-based methods, and hyperspectral sensors.

We would like to invite you to submit articles on new instruments, methods, algorithms, datasets, and their applications to underwater objects and structures measurements, managed by divers or by unmanned vehicles and 3D model generation; we would also like to invite you to submit articles on new methods using deep learning and machine vision to different wavelengths including hyperspectral, acoustic, and laser-based methods.

Finally, we aim to address problems related to the semantics of generated 3D models and to gather original research on application and background issues arising from the design of conceptual models, ontologies, and semantic web technologies applied to underwater archaeology, naval archaeology, and more generally digital human sciences (DH).

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.
