How frequently are GFM data updated?
From MyDewetra World
GFM products rely on S1 data, therefore their availability is mostly dependent on the latter.
As guaranteed by the service, the processing of the raw data requires less than 8 hours for GFM's products to be available.
Therefore the most important variable in play is S1's revisit time which is addressed in the [[FAQ#What_time_does_the_satellite_pass_over_my_area? | dedicated section] of the FAQ.
