Get topographic rasters — terrain

Calculate the SpatRasters needed for the terrain model.

Usage

terrain_model(
  topograp = TRUE,
  Polygon1,
  sourceCCL,
  sourceCCLRoughness,
  plotit = FALSE,
  verbose = FALSE
)

Arguments

topograp: Boolean value, which indicates if the terrain effect model should be enabled or not. Default is FALSE
Polygon1: The considered area as SpatialPolygon, SimpleFeature Polygon or coordinates as matrix/data.frame
sourceCCL: The path to the Corine Land Cover raster (.tif). Only required when the terrain effect model is activated.
sourceCCLRoughness: The source to the adapted Corine Land Cover legend as .csv file. Only required when terrain effect model is activated. As default a .csv file within this package (~/extdata) is taken that was already adapted manually.
plotit: Plots the elevation data
verbose: If TRUE it will print information for every generation. Default is FALSE

Value

A list of SpatRasters

Examples

if (FALSE) {
library(sf)
Polygon1 <- sf::st_as_sf(sf::st_sfc(
  sf::st_polygon(list(cbind(
    c(4651704, 4651704, 4654475, 4654475, 4651704),
    c(2692925, 2694746, 2694746, 2692925, 2692925)
  ))),
  crs = 3035
))
Polygon_wgs84 <- sf::st_transform(Polygon1, st_crs(4326))
srtm <- elevatr::get_elev_raster(locations = as(Polygon_wgs84, "Spatial"), z = 11)
res <- terrain_model(srtm, Polygon1)
}
