seed_tree_distmap {quaxnat}

Distance map to nearest seed source

Description

Creation of a distance map for the study area. The distance to the nearest seed source is calculated for every raster cell.

Usage

seed_tree_distmap(raster, species)

Arguments

raster

Raster data set with tree species classification of specific tree species and tree species groups.

species

Represents the numerical value by which the tree species of interest is encoded in the raster data set.

Value

A SpatRaster object containing the distances to seed source. The object has the same resolution and extent as the input raster.

Examples

## Create raster data set
 rr <- terra::rast(
 matrix(sample(0:10, 20 * 20, replace = TRUE),
        nrow = 20, ncol = 20))

## Compute distance for study area
distance <- seed_tree_distmap(raster = rr, species = "10")

## Plot the seed_tree_distmap
terra::plot(distance)
