Summarize categorical grids into time series table

Summarize grids into a table having columns: date, cellvalue (e.g. Seascape CLASS) and number of cells (n_cells).

Usage

grds_to_ts_cat(grds, ts_csv = NULL, verbose = F)

Arguments

grds

raster stack with more than one date, as returned by get_ss_grds

ts_csv

path to csv to save this time series table. Default is NULL, in which case the table is not saved. If path is set and already exists then that will be read in if all dates in the grds are present instead of recalculating and writing to ts_csv.

verbose

show messages of process. Useful for debugging. Default: FALSE.

Value

tibble of data

Details

This function is particularly helpful in between using get_ed_grds() and plot_ts_cat().
