Data for five lake-terminating glaciers in Iceland for the period 2008-2020, incuding: (1) Surface velocity rasters at different time periods. (2) Shapefiles of glacier terminus position at different time periods. (3) Shapefiles of proglacial lake area at different time periods. Velocity data were generated using select TerraSAR-X scenes and the offset tracking toolbox in SNAP (Sentinel Application Platform). Glacier teminus position and proglacial lake area were digitised from select Landsat 7, Landsat 8 and Sentinel-2 scenes. Full methodology is given in the accompanying paper that is currently in review (preprint DOI to follow). Glaciers of study are Skaftafellsjökull, Svínafellsjökull, Kvíárjökull, Fjallsjökull and Breiðamerkurjökull, all of which are found on the southern side of the Vatnajökull Ice Cap in southeast Iceland. Data for Fjallsjökull and Breiðamerkurjökull are for the period 2008-2020, whereas data for Skaftafellsjökull, Svínafellsjökull, Kvíárjökull are for the period 2010-2020 (there was no TerraSAR-X data from 2008 for these three glaciers).
