Topography is one of the main factors controlling processes taking place in the near-surface layer of the planet. At the same time, being a result of the interaction of endogenous and exogenous processes of different scales, topography reflects the geological structure of a terrain.
Digital terrain modeling and geomorphometry deals with quantitative modeling and analysis of the topographic surface and relationships between topography and other natural and artificial components of geosystems. Digital terrain analysis and geomorphometric modeling are widely used to solve various multiscale problems of geomorphology, hydrology, soil science, geology, geophysics, geobotany, glaciology, oceanology, climatology, planetology, and other disciplines.
In digital terrain modeling and geomorphometry, the initial data are digital elevation models (DEMs). Currently, DEMs are predominantly produced from remote sensing data. To create medium-resolution DEMs (tens of meters resolution), satellite data are used. Nearly-global models (e.g., SRTM1 DEM, ASTER GDEM, AW3D30 DSM) are currently utilized for producing filtered and edited DEMs with a regional, national, and global coverage. To create high- and very high-resolution DEMs (meter- and centimeter-range resolution), data from unmanned aerial systems (UASs) are used.
To present a current overview of the advancement of remote sensing and photogrammetry in digital terrain modeling and geomorphometry, we invite papers on the following but non-exhaustive list of topics:
- Methods to produce and edit near-global and regional DEMs using publicly available, satellite-based DEMs (e.g., SRTM1 DEM + ASTER GDEM + AW3D30 DSM);
- Methods to derive high- and very high-resolution DEMs from UAS-based imagery;
- Methods to reduce high-frequency noise in UAS-based, high- and very high-resolution DEMs;
- Methods to remove artifacts from satellite- and UAS-based DEMs;
- Application of satellite- and UAS-based DEMs to solve multiscale problems of geosciences.

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 2500 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.
