The GEE tutorial shows how to mask an image for one pixel value using .eq(pixel value).
However, I want to mask all pixels in an image with a value of 15 or less in this dataset
var riverflow = ee.Image('WWF/HydroSHEDS/15ACC'); var flowAccumulation = riverflow.select('b1');
And now I need to use .updateMask. This must be very straightforward right?
