Geomorphometry 2021 - Announcement

Geomorphometry 2021: Conference and Workshops

The Geomorphometry Society and the Organizing Committee are pleased to announce the sixth Geomorphometry Conference to be held in Perugia, Italy, September 13-17 2021. The event is hosted by the Research Institute for Geo-Hydrological Protection of the Italian National Research Council (CNR IRPI) and the Department of Physics and Geology of the University of Perugia. Details on past editions of the conference are on the website.

Conference website:

The previous edition of the conference was postponed due the global pandemic. Contributions to the conference were evaluated by the scientific/organizing committee, and authors were notified of acceptance/rejection of their extended abstract; revised abstracts were collected into a volume entitled “Geomorphometry 2020 Conference Proceedings” edited by M. Alvioli, I. Marchesini, L. Melelli & P. Guth and published by CNR Edizioni (Rome, 2020). Individual contributions and the whole volume can be downloaded here.

Authors were invited to extend their contributions to full article length, and submit them for pubblication in a special issue of Transactions in GIS, entitled “Geomorphometry 2020” which wil be published in the third quarter of 2021 (Volume 25); submissions for the 2020 special issue are currently closed.

The 2021 conference will tentatively be a mixed in presence - online event, so that whoever can/want to travel to Perugia is welcome to do so, but people will still be able to participate in the conference remotely. Please refere to the Covid-19 link on the main page for further and updated information about this. For online presenters: we are aware of the different time zones issue; we are working on it.

Submissions to the 2021 event are now close and submitted papers have been peer reviewed; contributions accepted for the 2020 will be retained for the 2021 event. Based on the actual number of new accepted contributions we will consider publishing a new conference proceedings and/or a new journal publication.

Perugia, Italy - Venue of Geomorphometry 2021

Geomorphometry is the science of quantitative land surface analysis. It gathers various mathematical, statistical and image processing techniques that can be used to quantify morphological, hydrological, ecological and other aspects of a land surface. Common synonyms for geomorphometry are geomorphological analysis, terrain morphometry or terrain analysis and land surface analysis.

This paper presents an evaluation of Structure from Motion-Multi View Stereo (SfM-MVS) to obtain high-resolution elevation data of coastal sand dunes based on images acquired by Remotely Piloted Aircraft (RPA).

The analyzes were made using GRASS-GIS trough python scripts. Denoising of SfM-MVS DEMs were made with WhiteBox. Although the DEMs cannot be shared in GitHub (due to space limitations), the scripts can be used as an educational resource.

The LiDAR and SfM-MVS datasets can be accessed at:

In the paper, a first assessment of the TanDEM-X DEMs over Brazilian territory is presented through a comparison with SRTM, ASTER GDEM and ALOS AW3D30 DEMs in seven study areas with distinct geomorphological contexts, vegetation coverage, and land use.

The analyzes were made using GRASS-GIS trough python scripts. Although the DEMs cannot be shared in GitHub (due to both space limitations and licensing of TanDEM-X), the scripts can be used as an educational resource.

Manuscript preparation guidelines 2018

This page contains some basic instructions on how to prepare and submit a Camera Ready Copy (CRC) of the short papers for the Geomorphometry conference. We typically do not provide any technical support, which means that each author is responsible to format the article following the preparation guidelines and submit a CRC version of manuscript (see an example). Submissions that do not closely follow the manuscript preparation guidelines might be removed from the revision process. The publication process is illustrated in the graph below:


Use one of the following templates to prepare your 2-4 pages summary paper (read also the manuscript preparation guidelines):



General instructions:

  1. Do not submit poorly prepared, incomplete and/or already used materials. Your paper will be reviewed by three members of the scientific committee.
  2. Extended abstracts must be original works by the authors, not be currently under review in the same form by another outlet and not submitted elsewhere prior to the notification date.
  3. Closely follow the manuscript preparation guidelines. Manuscripts that do not comply with the guidelines will be removed from the review process.
  4. The paper has to be at least 2 and at most 4 pages long.
  5. We accept only font-enbeded, high-quality graphics PDF versions of the manuscript. Do not submit MS Word documents or similar. To generate a PDF version of the article, please consider using CutePDF Writer or similar freeware.
  6. Closely follow the indicated deadlines. We take no responsibility for delayed or incomplete reviews.


  • Consider preparing a summary paper that describes your research and gives an overview of the research results in the period of last 3-5 years. Focus on what is really novel about your approach and what still has to be done to reach the research objectives.
  • Give concrete examples and illustrations of data analysis schemes, data sets, methodological concepts and results received.
  • Concept papers and new research proposals are also welcome, assuming that they will evolve into full-length articles.
