Recognition of landslides in lunar impact craters

European Journal of Remote Sensing, 2018
Landslides have been observed on several planets and minor bodies of the solar System, including the Moon. Notwithstanding different types of slope failures have been studied on the Moon, a detailed lunar landslide inventory is still pending. Undoubtedly,

Morphological Features-Based Descriptive Index System for Lunar Impact Craters

ISPRS International Journal of Geo-Information, 2017
Lunar impact craters are important for studying lunar surface morphology because they are the most typical morphological units of the Moon. Impact crater descriptive indices can be used to describe morphological features and thus provide direct evidence ...

Crater Detection Dependence on Resolution, Incidence Angle, Emission Angle, and Phase Angle

Geophysical Research Letters
Impact crater population detection and measurement is critical to understanding solar system bodies and dynamics. However, the ability to detect all possible craters under different lighting and camera geometries has not been systematically studied ...

The self‐secondary crater population of the Hokusai crater on Mercury [PDF]

Geophysical Research Letters, 2016
AbstractWhether or not self‐secondaries dominate small crater populations on continuous ejecta deposits and floors of fresh impact craters has long been a controversy. This issue potentially affects the age determination technique using crater statistics.

From the Moon to Mercury: Release of Global Crater Catalogs Using Multimodal Deep Learning for Crater Detection and Morphometric Analysis

Remote Sensing
This study has compiled the first impact-crater dataset for Mercury with diameters greater than 400 m by a multimodal deep-learning pipeline. We present an enhanced deep learning framework for large-scale planetary crater detection, extending the ...

Deep learning detects entire multiple-size lunar craters driven by elevation data and topographic knowledge

Geo-spatial Information Science
Lunar craters are important geomorphological features, that provide valuable insights into lunar morphology, geology, and impact processes. However, the current understanding of lunar craters of different sizes, especially smaller craters (diameter
