Series of Pixel Values

Converts layer-wise values from cube2table() into SWAT-style input: a time series for each pixel in the study area.

Usage

layervalues2pixel(
  layer_values,
  main_tbl,
  col_name = "20220101",
  inline_output = TRUE,
  path_output = NULL,
  append = FALSE
)

Arguments

layer_values

List. Values extracted per raster layer (from cube2table()).

main_tbl

A table with pixel metadata (e.g., from main_input_var()), used to name each output table.

col_name

Column name for each SWAT input table. Typically the first date in the time series (e.g., "20220101").

inline_output

Logical. If TRUE, returns a list of data.tables.

path_output

Directory to write one file per pixel when inline_output = FALSE.

append

Logical. If TRUE, append to existing files; otherwise overwrite.

Value

A list of tables (when inline_output = TRUE) or a set of files in path_output (one for each pixel).

Examples

if (FALSE) { # \dontrun{
# Example (pseudo-code):
# lv <- cube2table(input_path, var = "tmin", n_layers = 10, study_area)
# mt <- main_input_var(study_area, var_name = "tmin")
# out <- layervalues2pixel(lv, mt, col_name = "20220101", inline_output = TRUE)
} # }
