Recently I have derived a correlation equation between biomass and canopy height using sample tree parameters from field. The equation is
Biomass = 0.0001(Height)^ 2.895.
I tried to calculate the biomass using the height derived from my Canopy Height Model (CHM) using the following code,
var Biomass = CHMfinal.exp(2.895).multiply(0.0001).rename('AGB')
where, CHMfinal is my height data
but this is not working and giving me an error saying
'Too many (2) arguments to function: Image.exp(value) Computes the Euler's number e raised to the power of the input. Args: value (Image): The image to which the operation is applied. in <global>, line 274 in <global>, line 276'
Can anyone say where I am doing wrong?
