This is the primitive layer rendered by CPUGridLayer after aggregation. Unlike the CPUGridLayer, it renders one column for each data object.

The GridCellLayer can render a grid-based heatmap. It is a variation of the ColumnLayer. It takes the constant width / height of all cells and top-left coordinate of each cell. The grid cells can be given a height using the getElevation accessor.

import DeckGL from '';
import {GridCellLayer} from '';

function App({data, viewState}) {
   * Data format:
   * [
   *   {centroid: [-122.4, 37.7], value: 100},
   *   ...
   * ]
  const layer = new GridCellLayer({
    id: 'grid-cell-layer',
    pickable: true,
    extruded: true,
    cellSize: 200,
    elevationScale: 5000,
    getPosition: d => d.centroid,
    getFillColor: d => [48, 128, d.value * 255, 255],
    getElevation: d => d.value

  return <DeckGL viewState={viewState}
    getTooltip={({object}) => object && `height: ${object.value * 5000}m`} />;


To install the dependencies from NPM:

npm install
# or
npm install
import {GridCellLayer} from '';
new GridCellLayer({});

To use pre-bundled scripts:

<script src="^8.0.0/dist.min.js"></script>
<!-- or -->
<script src="^8.0.0/dist.min.js"></script>
<script src="^8.0.0/dist.min.js"></script>
new deck.GridCellLayer({});


Inherits from all Base Layer properties.

Render Options

cellSize (Number, optional) transition-enabled
  • Default: 1000

Size of each grid cell in meters

coverage (Number, optional) transition-enabled
  • Default: 1

Cell size scale factor. The size of cell is calculated by cellSize * coverage.

elevationScale (Number, optional) transition-enabled
  • Default: 1

Elevation multiplier. The elevation of cell is calculated by elevationScale * getElevation(d). elevationScale is a handy property to scale all cell elevations without updating the data.

extruded (Boolean, optional)
  • Default: true

Whether to enable grid elevation. If set to false, all grid will be flat.

material (Object, optional)
  • Default: true

This is an object that contains material props for lighting effect applied on extruded polygons. Check the lighting guide for configurable settings.

Data Accessors

getPosition (Function, optional) transition-enabled
  • Default: x => x.position

Method called to retrieve the top left corner of each cell. Expecting [lon, lat].

getColor (Function|Array, optional) transition-enabled
  • Default: [255, 0, 255, 255]

The rgba color of each object, in r, g, b, [a]. Each component is in the 0-255 range.

  • If an array is provided, it is used as the color for all objects.
  • If a function is provided, it is called on each object to retrieve its color.
getElevation (Function|Number, optional) transition-enabled
  • Default: 1000

The elevation of each cell in meters.

  • If a number is provided, it is used as the elevation for all objects.
  • If a function is provided, it is called on each object to retrieve its elevation.
