The satellite images include Landsat 5, Landsat 7, Landsat 8, ERS-1, ERS-2, Envisat Image Mode, TerraSAR-X and Sentinel 1A and B Single Look Complex images. The dataset has been compiled over approximately 20 years and processing algorithms and parameters have evolved and improved. The more recent measurements are likely to be the most accurate. Data collection: Image processing and feature tracking were carried out using Gamma Remote Sensing software. There are 341 data points. Data quality: The accuracy of the data varies according to the initial spatial resolution and geolocation of the images and is likely to improve throughout the time sequence as processing and algorithms have improved. Bevan et al. (2012) estimated the accuracy of all types of images up to 2012 to be better than 0.5 metres/day. asNeeded completed
