add_cesium {mapdeck}

Add Cesium

Description

Renders 3D tiles data from Cesium ION assets. To use this layer you need a Cesium ION account https://cesium.com/learn/cesiumjs-learn/cesiumjs-quickstart/#your-first-app. This layer is experimental

Usage

add_cesium(map, data, point_size = 2, layer_id = NULL, ion_token = NULL)

Arguments

map

a mapdeck map object

data

data to be used in the layer. All coordinates are expected to be EPSG:4326 (WGS 84) coordinate system

point_size

size of point in pixels

layer_id

single value specifying an id for the layer. Use this value to distinguish between shape layers of the same type. Layers with the same id are likely to conflict and not plot correctly

ion_token

ion asset token

Examples

## Melbourne point cloud
ion_asset <- 43978
ion_token <- "ION_TOKEN"
tile_data <- paste0("https://assets.ion.cesium.com/",ion_asset,"/tileset.json")

mapdeck(
  location = c(144.95, -37.82)
  , zoom = 14
  , pitch = 60
) %>%
 add_cesium(
   data = tile_data
   , ion_token = ion_token
 )
