Soil mask

[Prasanth Chigurupati]

Hi

To remove the soil I have done with the given function (soil mask), but it seems to want to mask properly, please suggest the proper function.

Thank you

Hi Prasanth,

The better way to remove the soil is to follow what I described at the link: https://github.com/OpenDroneMap/FIELDimageR#P6

Using the function fieldIndex() with the original image, you must calculate different indices ("BI", "BGI", "SCI", etc) and chose one to identify the soil. 

Then, using fieldMask() you can use this index, the value to crop (cropValue), and the direction to crop (cropAbove = TRUE or FALSE).

Please, let me know if you got this.

Best
