Introduction to maps

A map is a collection of layers. You use a map together with a map view to display layers of geographic data in 2D. Most applications contain a basemap layer to display geographic data with streets or satellite imagery. The data for a basemap layer is typically provided by basemap services, such as the basemap styles service or static basemap tiles service.

You can use basemap layers to:

• Display different types of geographic data of the world for a map.
• Display vector tile styles such as streets, navigation, outdoor, and light gray canvas.
• Display map tiles for oceans, satellite, imagery, and hillshade.
• Display custom vector basemap styles with your own colors, glyphs, and fonts.

Basemap styles service

The basemap styles service is a location service that provides basemap styles and data for the extent of the world. The service includes ArcGIS and OSM styles. There are default basemap styles such as streets, navigation, light gray canvas, and imagery. The data for each style is provided through vector tile layers and map tile layers hosted in ArcGIS and is stored in a Web Mercator spatial reference.

How to access basemap styles service

To access vector basemap layers, you reference both the main Esri Leaflet plugin and the vectorBasemapLayer plugin.

1. Reference the Esri Leaflet and vector plugins.
2. Set the access token and define a basemap style enumeration.
3. Instantiate the vectorBasemapLayer class and pass the basemap enumeration.
4. Add it to the map.

Static basemap tiles service

The static basemap tiles service is a location service that provides raster basemap tiles for the extent of the world. The service supports default basemap styles such as streets, navigation, outdoor, and light gray canvas. The tiles are supplied as 512x512 .png files in a Web Mercator spatial reference.

How to access static basemap tiles service

To access static basemap tiles, you reference both the main Esri Leaflet plugin and the esri-leaflet-static-basemap-tile plugin.

1. Reference the Esri Leaflet and static basemap tile plugins.
2. Set the access token and define a basemap style enumeration.
3. Instantiate the staticBasemapTileLayer class and pass the basemap enumeration.
4. Add it to the map.
