The GSI shortcall in 2015 gave us the opportunity to look at ways of applying bathymetric derivation algorithms to high resolution imagery. We looked at RapidEye (5m), Pleiades (2m), light aircraft and drones (sub-decimetre). The project focussed primarily on the airborne and drones (report available here) but gave us valuable insights on what we needed to take the algorithms and begin to adapt them for satellite data provided through ESA TPM license. We were then able to advance the work begun with the Dublin bay bathymetry paper and look at applying spatial and non-spatial models to improve accuracy of satellite derived bathymetry (spoiler - helps as depth increases). This was a multi partner project - I've been working on it over the 4 years and includes NCG, Rothamstead Research,Geological Survey and industry. Great to see it finally published in such a good journal.
