Rapid digitization of historical land-use maps in R

Description

Contains four functions for smoothing, colour assignment and classification of scanned historical land-use maps. Draws mostly from the terra package by R. Hijmans.

Usage

smooth_map(in.raster, window.size = 25, smooth.function = mean, dark.rm = TRUE, darkValue = 100, clip.frame = FALSE)

click_sample(in.raster, cats = NULL, npoints = 10, print.values = FALSE, type = "p", plot.cols = TRUE, ...)

plot_colour_table(colour.table, errors = 0)

class_map(in.raster, colour.table = NULL, errors = 0, exceptions = NULL, plot.raster = TRUE, raster.summary = FALSE, save.raster = FALSE, out.file = NULL)
