Automated landform classification and mapping using a combined textural-morphometric approach: the Congo basin and surroundings [PDF]

, 2022
International audienceAn automatic method of landform mapping applicable to large continental areas is presented, based on 30-meter SRTM (Shuttle Radar Topography Mission) data and combining texture analysis using Fourier 2D periodograms (FOTO method ...

Geophysical and remote sensing - based approach to model regolith thickness in a data - sparse environment [PDF]

, 2011
Mapping regolith thickness to bedrock is important for environmental modeling in general and for seismic hazard assessment in particular. However, regolith thickness is often ignored in such studies because of its presumed difficulty of mapping in many ...

Automatic Classification of Planetary Surfaces Using Autoencoders With Applications to Dunes in the North Polar Erg of Mars

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract The study of planetary surface processes has traditionally relied on the manual interpretation of spacecraft images. While manual image analysis methods are robust and well‐established, they become impractical when the volume of available data is large and may introduce observer bias.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Martian Proton Albedo as Signature of Near‐Surface Water

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

Origin of Late Noachian‐Early Hesperian Valley Networks on Mars: Insights From Landform Evolution and Ice Sheet Modeling

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

New regolith mapping approaches for old Australian landscapes. [PDF]

, 2014
The regolith, or ‘critical zone’, forms a discontinuous layer that covers large areas of Earth’s terrestrial surface. It is a dynamic zone that forms and changes through time in response to interactions between air, rocks (minerals), water and biota ...
