Hi there,

The estimated plant height has the same unit of your DSM (Digital Surface Model), which is the output from the orthomosaicin step. 

Normally DSM is in meters (m), but you need to check it in your image.

Use one of the following functions (crs or projection) to have an idea about resolution ( e.g., 0.0175 m x 0.0175 m = 1.75 cm x 1.75 cm):

library(raster)
Test<-raster(DSM.tif)
crs(Test)
projection(Test)
Test

Best,
Filipe

Dr. F. matias,

Hello! I am a Ph.D. student. I'm attempting to use this program as part of my phenotyping method. I am having some difficulty in understanding plant height, Please let me know how to convert those EPH values to centimeters and logic behind that.

Thank you very much
