    Improved bathymetric model of Lake Urmia derived from satellite images from Landsat sensors TM, ETM+, and OLI and recent bathymetric model, based on an echo sounding survey in 2017. The existing bathymetric data shows some inaccuracies in the shallow areas of the lake a...

    High resolution remotely sensed bathymetric data is rapidly increasing in volume, but analyzing this data requires a mastery of a complex toolchain of disparate software, including computing derived measurements of the environment. Bathymetric gradients play a fundament...

    Space-borne instruments can measure river water surface elevation, slope and width. Remote sensing of river discharge in ungauged basins is far more challenging, however. This work investigates the estimation of river discharge from simulated observations of the forthco...

    Estimating river discharge from in situ and/or remote sensing data is a key issue for evaluation of water balance at local and global scales and for water management. Variational data assimilation (DA) is a powerful approach used in operational weather and ocean forecas...

    Coastal water mapping from remote-sensing hyperspectral data suffers from poor retrieval performance when the estimation parameters have little effect on subsurface reflectance, especially due to the ill-posed nature of the inversion problem. For example, depth cannot a...

    During the past few years there was an increasing demands of needs for mapping the bottom of water, either because it was needed for Navigation Safety, Nautical charts, or for Pollution controlling, mineral and fish industries. Over the years the methods of bathymetry a...

  • / Au cours de ce stage, j'ai développé de nouvelles méthodes d'estimation (d'inversion) de la bathymétrie et de la hauteur d'arbres à partir de formes d'onde LiDAR. Ces nouvelles méthodes statistiques, utilisant un apprentissage, tombent dans le domaine dit de l'analyse...

  • Possessing accurate, spatial and current data on the water levels and the depths are necessary for anticipation and better management of coastal and continental waters. Among the remote sensing techniques to monitor the water bathymetry and altimetry, the LIDAR appears ...
