Hi LokeRichard suggested using a NDVI approach which would require data in the Near Infrared (NIR) band.  An orthomisaic would contain 3 colour bands, but not the NIR.  NDVI provides an understanding of plant greenness and health and may not be suitable for detecting oil palm's.  If you are getting 90 percent plus with your current approach , you may find that you will spend 4 times longer capturing the additional 10 percent.  NIR data,are available from various satellite sensors however, their resolution would not work at the individual plant level.Some drone sensors record the NIR band.Kirk SchmidtSent from my Galaxy
