The trajectory map consistently displays an incorrect colour scheme.

Problem

The trajectory map consistently displays an incorrect colour scheme. This happens because tidyterra assigns colours based on the number of classes in the categorical raster. If the colour palette is assigned according to a column in the raster attribute table that doesn't match the values in the raster file, tidyterra will display the incorrect colour scheme.

Potential Solution

Before plotting, the luc_trajectory_map spatres object should be re-classified into the 9 classes below:

# Create the lookup table

  ~ID_traj, ~trajectory,                          ~color_pallette,

  2, "Recovery to tree cropping",          "#8B4513", # Saddle Brown
  3, "Recovery to forest",                 "#228B22", # Forest Green
  4, "Recovery to agroforest",             "#4B0082", # Indigo
  5, "Other",                              "#808080", # Grey
  6, "Loss to logged-over forest",         "#F28500", # Dark Olive Green
  7, "Loss to infrastructure",             "#FF0000", #Red
  8, "Loss to cropland",                   "#FFFF00", # Yellow
  9, "Loss to bare land and abandoned",    "#ffb6c1",  # Pink
)
