Scale factors - multiply or divide?


An Earth Engine user mentions that the data should be divided, not multiplied by, scale factors.

The doc does not say this explicitly. What’s the right operation here?


I can’t read the ticket you are referring to. I have no access.
But the values of data needs to be multiplied with the scale factor.
The raw values are between 0 and 65535. The scale value is for example 0.008765390142.
To get reasonable values you do
20753 * 0.008765390142 = 180.3533
If there is also an offset specified, add it afterwards.
So in general to get the geophysical value do
v = raw * factor + offset
