  • This paper describes advances in an automatic approach for the detection of sand dunes of Mars, based on supervised learning techniques. A set of features (gradient histogram) is extracted from the remotely sensed images and 2 classifiers (Support

  • The AA. (i) adapt and extend extant techniques to provide a suite of semi-automatic tools which calculate crest orientation, wavelength, height, asymmetry direction and asymmetry ratios of bedforms, and then (ii) undertake sensitivity tests

  • This study assesses the runoff from 10 medium-sized catchments in the Geba river basin, a subcatchment of the Nile in the semi-arid degraded northern Ethiopian highlands. Flow depth records were automatically obtained every 10 minutes during

  • -automatic breakline extraction procedures to multi-temporal Lidar data. The breakline extraction is based on filter methods derived from digital image analysis. Furthermore beach width changes are analyzed. Different annual as well as seasonal coastal change

  • with a constrained breaching algorithm that explicitly takes automatically identified channel locations into account. The AA. applied these methods to a low relief landscape, but the results can be transferred to flow network derivation of DEMs in moderate

  • , snow and ground temperature sensors, as well as automatic time-lapse cameras on a leeward facing plateau edge were used to study seasonal cornice dynamics. These techniques allowed for monitoring of cornice accretion, deformation and collapse/melting
