Calculate Trajectory Map

This function calculates the trajectory map by reclassifying two rasters (representing land cover at two different time points), concatenating them, and then adding categorical information based on a provided lookup table.

Usage

calc_trajectory_map(
  lc_t1_,
  lc_t2_,
  lookup_traj_reclass,
  lookup_trajectory_complete,
  trajectory_column_name = "trajectory"
)

Arguments

lc_t1_

A raster object representing the land cover at time 1.

lc_t2_

A raster object representing the land cover at time 2.

lookup_traj_reclass

A data frame containing the reclassification rules.

lookup_trajectory_complete

A data frame containing the lookup table for trajectories.

trajectory_column_name

A string representing the column name for the trajectory in the lookup table.

Value

A raster object representing the trajectory map.

Examples

if (FALSE) {
# assuming we have two raster objects "lc_t1", "lc_t2",
#a reclassification table "lookup_traj_reclass",
# and a lookup table "lookup_trajectory_complete"
my_trajectory_map <- calc_trajectory_map(lc_t1_, lc_t2_, lookup_traj_reclass,
lookup_trajectory_complete,
trajectory_column_name = "trajectory")
}
