create_linestring_3D: Create a 3D Linestring Map

Description

This function creates a 3D linestring map using Mapbox GL JS and saves it as an HTML file. The data should not contain complex objects like list columns. The map visualizes linestring data with an associated green index, allowing for interactive exploration of the data.

Usage

create_linestring_3D(
  data,
  green_index_col,
  mapbox_token,
  output_file = "linestring_map.html",
  color_palette = "interpolateViridis",
  map_center = NULL,
  map_zoom = 11
)

Value

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

Arguments

data

An sf object containing linestring geometries and associated data.

green_index_col

Character, name of the column containing the green index values.

mapbox_token

Character, Mapbox access token for rendering the map.

output_file

Character, name of the output HTML file. Default is "linestring_map.html".

color_palette

Character, name of the D3 color palette to use. Default is "interpolateViridis".

map_center

Numeric vector, longitude and latitude of the map center. Default is NULL (computed from data).

map_zoom

Numeric, initial zoom level of the map. Default is 11.

Examples

if (interactive()) {
  # Create example data
  lines <- st_sf(
    id = 1:5,
    geometry = st_sfc(
      st_linestring(matrix(c(0,0, 1,1), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(1,1, 2,2), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(2,2, 3,3), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(3,3, 4,4), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(4,4, 5,5), ncol=2, byrow=TRUE))
    ),
    green_index = runif(5)
  )
  st_crs(lines) <- 4326
  mapbox_token <- "your_mapbox_token"
  create_linestring_3D(lines, "green_index", mapbox_token)
