Create a 3D Hexagon Map Using H3 and Mapbox GL JS

Description

This function creates a 3D hexagon map using H3 and Mapbox GL JS. The input data can be points, linestrings, polygons, or multipolygons.

Usage

create_hexmap_3D(
  data,
  value_col,
  label_col = NULL,
  mapbox_token,
  output_file = "hexagon_map.html",
  color_palette = "interpolateViridis",
  max_height = 5000,
  map_center = NULL,
  map_zoom = 11,
  h3_resolution = 9
)

Arguments

data	An sf object containing geographical data.
value_col	Character, the name of the value column.
label_col	Character, the name of the label column (optional).
mapbox_token	Character, your Mapbox access token.
output_file	Character, the file path to save the HTML file. Default is "hexagon_map.html".
color_palette	Character, the D3 color scheme to use. Default is "interpolateViridis".
max_height	Numeric, the maximum height for the hexagons. Default is 5000.
map_center	Numeric vector of length 2, the center of the map. Default is NULL.
map_zoom	Numeric, the zoom level of the map. Default is 11.
h3_resolution	Numeric, the H3 resolution for hexagons. Default is 9.

Value

NULL. The function creates an HTML file and opens it in the viewer or browser if run interactively.

Examples

if (interactive()) {
  # Generate random data
  lon <- runif(100, min = 8.49, max = 8.56)
  lat <- runif(100, min = 47.35, max = 47.42)
  green_index <- runif(100, min = 0, max = 1)
  data <- data.frame(lon = lon, lat = lat, green_index = green_index)
  data_sf <- sf::st_as_sf(data, coords = c("lon", "lat"), crs = 4326)

  # Specify your Mapbox access token
  mapbox_token <- "your_mapbox_access_token_here"

  # Create the 3D hexagon map
  create_hexmap_3D(
    data = data_sf,
    value_col = "green_index",
    mapbox_token = mapbox_token,
    output_file = "map.html",
    color_palette = "interpolateViridis"
  )
}
