Integration of Webcam data for deriving Snow cover and snow depth from Sentinel-1, Sentinel-2 and Pléiades data
01.07.2018 - 31.10.2019
Forschungsförderungsprojekt
The overall goal of WebSnow is to study the feasibility of using webcam data as reference for (i) increasing the spatial resolution and accuracy of snow cover maps derived from Sentinel-1 and Sentinel-2 data and (ii) assessing the snow depth from image matching data (e.g. from Pléiades). The used outdoor webcam images from the Bergfex network,
consisting of hundreds of webcams distributed over the Alpine region, provide high temporal (~every 15 minutes) and spatial (<10 m) resolution and thus offer a huge potential (i) to complement and improve satellite-derived snow information, and (ii) to be used as a reference for improved validation. The assimilation of satellite-derived snow products with
snow information from webcams is to our knowledge a totally new approach, and has the potential to significantly improve the quality of high resolution satellite snow products. The approaches will be applied for case studies in Austria and Switzerland, where high resolution snow products will be generated from archived and recent acquisitions of Sentinel-1, Sentinel-2, Pléiades and webcam data. Finally, demonstrating the feasibility of the proposed approach will promote the exploitation of satellite images in an operational context in a challenging environment.
