create_linestring_3D: Create a 3D Linestring Map

In greenR: Green Index Quantification, Analysis and Visualization

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 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
)

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.

Value

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

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)
}
