Calculate land use and land cover change trajectory
ques_pre_trajectory.Rd
This function calculates the trajectory map, creates a cross-tabulation of land cover and administrative zones, and plots a bar chart of the trajectory data.
Usage

lc_t1_,
lc_t2_,
admin_,
lookup_traj_reclass,
lookup_trajectory_complete,
trajectory_column_name = "trajectory",
convert_to_Ha = TRUE
)
Arguments
- lc_t1_
A raster layer representing land cover at time 1.
- lc_t2_
A raster layer representing land cover at time 2.
- admin_
A raster layer representing administrative zones.
- lookup_traj_reclass
A lookup table for reclassifying trajectories.
- lookup_trajectory_complete
A lookup table for completing trajectories.
- trajectory_column_name
The name of the trajectory column. Default is "trajectory".
- convert_to_Ha
Logical. If TRUE, the pixel counts are converted to hectares. Default is TRUE.
