| **Layer Type** | **Description** | **Layer Preview Image** |
| --- | --- | --- |
| [`3D Layer`](https://docs.foursquare.com/analytics-products/docs/layer-3d) | 3D layer displays 3D models on map by using latitude and longitude coordinates. |  |
| [`Arc Layer`](https://docs.foursquare.com/analytics-products/docs/layer-arc) | Arc layers are useful for visualizing the distance between two points as well as comparing distances in 3D. |  |
| [`Cluster Layer`](https://docs.foursquare.com/analytics-products/docs/layer-cluster) | Cluster layers visualize aggregated data based on a geospatial radius. |  |
| [`Flow Layer`](https://docs.foursquare.com/analytics-products/docs/layer-flow) | Flow layers visualize origin-destination movement patterns between latitude and longitude coordinates. |  |
| [`Geojson/Polygon Layer`](https://docs.foursquare.com/analytics-products/docs/layer-polygon) | Polygon layers can display either paths, polygons or points. For example, a path layer can display data like trip routes. |  |
| [`Grid Layer`](https://docs.foursquare.com/analytics-products/docs/layer-grid) | Grid layers are similar to heatmap layers. They show the density of points. |  |
| [`H3 Layer`](https://docs.foursquare.com/analytics-products/docs/layer-h3) | H3 layers visualize spatial data using [H3 Hexagonal Hierarchical Spatial Index](https://eng.uber.com/h3/). |  |
| [`Heatmap Layer`](https://docs.foursquare.com/analytics-products/docs/layer-heatmap) | Heatmap is a graphical representation of data in which values are represented as colors. |  |
| [`Hexbin Layer`](https://docs.foursquare.com/analytics-products/docs/layer-hexabin) | Hexbin layers aggregate points into hexagons. The counts can be represented through color and/or height. |  |
| [`Hex Tile Layer`](https://docs.foursquare.com/analytics-products/docs/layer-hex-tile) | Hex Tile layers use [Foursquare's proprietary Hex Tile tiling system](https://docs.foursquare.com/analytics-products/docs/hex-tiles). |  |
| [`Icon Layer`](https://docs.foursquare.com/analytics-products/docs/layer-icon) | Icon layers are a type of point layer. They allow you to differentiate between points by assigning icons to points based on a field. |  |
| [`Line Layer`](https://docs.foursquare.com/analytics-products/docs/line-layer) | Line layers are the 2D version of arc layers. Both draw a line between two points to represent distance, but in a line layer, the drawing lies flat on the map. |  |
| [`Point Layer`](https://docs.foursquare.com/analytics-products/docs/layer-point) | Point layers draw points for a given event or object based on its latitude and longitude. |  |
| [`Raster Layer`](https://docs.foursquare.com/analytics-products/docs/layer-raster) | Raster layers show aerial photographs, imagery from satellites, or even scanned maps. |  |
| [`S2 Layer`](https://docs.foursquare.com/analytics-products/docs/layer-s2) | To use S2 layers, you need to assign a column containing S2 tokens. |  |
| [`Trip Layer`](https://docs.foursquare.com/analytics-products/docs/layer-trip) | Visualize movement through animations, such as air travel over a period of time. |  |
| [`Vector Layer`](https://docs.foursquare.com/analytics-products/docs/layer-vector) | Vector layers use the three basic GIS features to represent real-world features in digital format. |  |
| [`WMS Layer`](https://docs.foursquare.com/analytics-products/docs/layer-wms) | WMS layers render map imagery optimized for the current viewport. |  |
