Given a data set which consists of pairs of longitudes and latitudes, is it possible to determine an estimate of the ocean bottom depth at that point?
I can find maps of estimated sea depths online (e.g. https://maps.ngdc.noaa.gov/viewers/bathymetry/), but I am not sure how to go about it extracting the data.
I could look at every single point, and look at the map and find the depth level, but I have > 1000 points so ....
