Statement

Methodology:

From 2012 to 2014 speeds were measured using feature-tracking of TerraSAR-X image pairs separated by 11 days. TerraSAR-X images were supplied by DLR.

Speeds from 2015 onwards were measured using feature-tracking of Sentinel-1A and Sentinel-1B images separated by 6 or 12 days. Sentinel images were supplied by ESA.

Data collection:

Feature tracking was carried out using Gamma Remote Sensing software 20190603.

Data quality:

All feature-tracked displacements were filtered twice: first by a signal to noise ratio based on the cross-correlation of image patches, and then according to deviation from the mean displacement within a neighbourhood. The displacements were converted from the SAR image geometry to ground range geometry, and the results geocoded using the RAMP DEM (Liu et al., 2015).
