wepp_mapper: Calculate spatial entities required for WEPP

In steffilazerte/LITAP: Landscape Integrated Terrain Analysis Package

Calculate spatial entities required for WEPP

Description

This function takes backup data frame output from flow_mapper() and form_mapper() calculates hillslope, channel segments and impoundment spatial entities required for input in to WEPP (Water Erosion and Prediction Project) (among other metrics). Based on FacetMapR by R. A. (Bob) MacMillan, LandMapper Environmental Solutions.

Usage

wepp_mapper(
  folder,
  chan_length = 200,
  upslope_threshold = 300,
  clean = FALSE,
  resume = NULL,
  log = TRUE,
  verbose = FALSE,
  quiet = FALSE,
  debug = FALSE
)

Arguments

folder	Character. Location of flow_mapper() output
chan_length	Numeric. Channel length maximum length. Used to split channels into segments
upslope_threshold	Numeric. Threshold of upslope cells to define channel cells. #' Cells with an upslope value larger than this are considered channel cells
clean	Logical. Remove all output files from previous runs in this folder?
resume	Character. From which stage should the run be resumed? (see
log	Logical. Create log file recording progress?
verbose	Logical. Output extra progress messages.
quiet	Logical. Suppress all messages.
debug	Logical. If TRUE, output files contain intermediate columns useful for debugging (e.g., 'buffer', 'seqno_buffer', etc.) Default FALSE.

Examples

## Not run: 
# First need to run flow_mapper()
flow_mapper(file = system.file("extdata", "testELEV.dbf", package = "LITAP"),
           out_folder = "./testELEV/", nrow = 90, ncol = 90, grid = 5)

# Now can run wepp_mapper()
wepp_mapper(folder = "./testELEV/")

## End(Not run)
