Rasterize VRI polygons — rasterize

rasterize_vri() will quickly rasterize a given VRI (multi)polygon using fasterize::fasterize() under the hood at a default resolution of 10x10 m per pixel. By default, the function filters out any polygons occurring >900m elevation as reported in the VRI 'Elevation' column.

Usage

rasterize_vri(path, layer, below_900m = TRUE, res = 10)

Arguments

path: Path to either .gdb directory, .shp file, or .gpkg containing the VRI polygons.
layer: If path is a Geodatabase or Geopackage, layer name of the VRI polygons.
below_900m: Logical (T/F). Should the function only rasterize polygons below 900m? Default TRUE. If FALSE, the function will ignore the 'Elevation' column and rasterize all polygons.
res: Resolution in meters of the resultant raster. Default 10 m^2.

Value

Examples

path <- "~/Documents/path/to/VRI.gdb"
layer <- "VRI_Algorithm_Jan11_2023"
vri <- rasterize_vri(path = path, layer = layer)
#> Error in rasterize_vri(path = path, layer = layer): could not find function "rasterize_vri"
