Producers / Owners ENVEO
Description Calving Fronts of Filchner-Ronne Ice Shelf in Antarctica, derived by Canny edge detection using CryoSat-2 swath data acquired from 2011-2018. The digitized calving fronts are stored in ESRI vector shape-file format. Swath elevations are produced by applying a swath processing algorithm to L1b CryoSat SARIn mode products. The swath elevation products are available from the UK Polar Data Centre. See: Wuite et al. 2019
