In waternumbers/wmts: A Web Map Tile Server written in R

Description

Function to generate tiles for 0.1 degree data

Usage

genTiles(
  rst,
  fcol,
  outdir = ".",
  minZ = 0,
  maxZ = 3,
  w = 512,
  h = w,
  lv = NULL,
  ...
)

Arguments

rst	a SpatRaster or file name to open as a Spatraster to generate tiles from
fcol	function to convert raster values into an RGBA matrix - see details
outdir	directory into which the tiles are written
minZ	lowest zoom level to generate
maxZ	maximum zoom level to generate
w	width of tiles in pixels
h	height of tiles in pixels
lv	values used to generage a legend. If NULL to legend is generated.
...	passed to terra project or terra resample

Details

This is naive generater. Defaults work well for plotting 0.1 degree data in a limited number of tiles. fcol should take a vector of n values and return an n hex colour values which should include transparency.
