Tilt raster and sf data

Description

Takes tilted maps and plots them with ggplot.

Usage

plot_tiltedmaps(
  map_list,
  layer = NA,
  palette = "viridis",
  color = "grey50",
  direction = 1,
  begin = 0,
  end = 1,
  alpha = 1
)

Arguments

map_list	sf or terra/stars/raster object.
layer	vector or list of names of each column in tilted sf object that should be used for coloring
palette	vector of palettes provided by the viridis and scico packages for rasters
color	a single color applied multiple times or a vector of color strings for points or linestrings
direction	vector of directions for viridis and scico color palettes
begin	vector of the of the start of interval the palette to sample colours from for viridis and scico color palettes
end	vector of the of the end of interval the palette to sample colours from for viridis and scico color palettes
alpha	vector of opacity for viridis and scico color palettes

Value

A ggplot object with stacked maps.

Examples

# tilt data
tilt_landscape_1 <- tilt_map(landscape_1)
tilt_landscape_2 <- tilt_map(landscape_2, x_shift = 50, y_shift = 50)

# plot
map_list <- list(tilt_landscape_1, tilt_landscape_2)
plot_tiltedmaps(map_list, palette = "turbo")

  y_tilt = 1,
  x_shift = 0,
  y_shift = 0,
  angle_rotate = pi/20,
  boundary = NULL,
  parallel = FALSE
)

Arguments

data	sf or terra/stars/raster object.
x_stretch	Stretch in x dimension. A numeric vector of lenght 1.
y_stretch	Stretch in y dimension. A numeric vector of lenght 1.
x_tilt	Tilt in x dimension. A numeric vector of lenght 1.
y_tilt	Tilt in y dimension. A numeric vector of lenght 1.
