Special Issue Information
Dear Colleagues,
Remote sensing (RS) currently occupies a privileged position in Earth observation (EO)-based studies and applications, as well as in Earth data science, allowing the monitoring, understanding and modelling of our environment and its evolution at a global scale and with an unprecedented spatio-temporal resolution. EO data have been employed to monitor croplands and forested areas, oceans and seas, urban settlements, mountainous areas or climate-related processes and natural hazards. In all these cases, the extraction of features and information from EO data, either qualitative or quantitative, as well as their temporal dynamics is an essential step to better characterizing and understanding these different environments and processes, their interactions, and to also disentangle anthropogenic effects.
For instance, land-cover classes and land-cover changes at the global scale can be regularly updated thanks to automatic classification methods that are applicable to several EO data sources, including multi-spectral, hyperspectral and synthetic aperture radar (SAR) images. In this context, the accurate extraction of features and the estimation of essential variables from EO data, their classification and analysis are research topics of high interest to the scientific community, especially when considering global applications. Indeed, the transfer of locally trained classification techniques or the generalization of classification methodologies to a global scale remain open questions. Nevertheless, novel and highly relevant questions are currently emerging in these domains thanks to new technological advances. New developments in EO capabilities provided by new satellite constellations or improved imaging technologies, or developments in classification based on machine learning or deep learning, could allow precise classification on a large scale and with an unprecedented temporal sampling. In addition, the availability of different EO data sources with high spatio-temporal resolutions may allow access to novel features, not accessible in low or medium resolution data, and trigger the development of new feature extraction techniques to better understand the data information content.
The main objective of this Special Issue is to address these emerging topics in feature-based methods for RS data processing and classification by gathering contributions on novel feature extraction techniques, advanced classification methodologies, but also algorithms able to improve and increase the understanding of EO-based variables derived from large and various RS imagery collections.

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).
