Rasterize a line using stars because fasterize doesn't work on lines and
rasterize is slow. Deprecated use terra::rasterize
Arguments
- sfLine
an sf object to be rasterized
- rast
a raster to use as template for the output raster
- value
a number value to give the background ie 0 or NA
Value
a RasterLayer where the value of cells that touch the line will be the row index of the line in the sf
Examples
CLUSexample <- prepExData(CLUSexample)
roadsLine <- sf::st_sf(geometry = sf::st_sfc(sf::st_linestring(
matrix(c(0.5, 4.5, 4.5, 4.51),
ncol = 2, byrow = TRUE)
)))
