Style vector tiles

Learn how to customize vector tilesA vector tile layer is a data layer used to access and display tiled data and its corresponding styles.Learn more based on their underlying feature data.

You can use Esri Leaflet to display vector tileA vector tile layer is a data layer used to access and display tiled data and its corresponding styles.Learn more data using custom styles. Esri Leaflet Vector supports the MapLibre style specification, which allows you to customize the fill, outline, opacity, and other properties of vector tiles to display data effectively. If your vector tiles are published from a feature serviceA feature service is a data service that provides access to spatial and non-spatial data in feature layers, feature layer views, and tables.Learn more, you can also perform data-driven visualizations based on attributesAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more of the original feature service.

Prerequisites

Steps

Review the source data

This tutorial uses the Santa Monica Mountains Parcels vector tile serviceA vector tile service is a data service that provides access to vector tile data and a style definition.Learn more. This vector tile service was created by publishing a feature serviceA feature service is a data service that provides access to spatial and non-spatial data in feature layers, feature layer views, and tables.Learn more as vector tiles using the portalArcGIS portal, also known as a portal, is a website with applications and tools that can be used to create, manage, access, and share geospatial content and data. It supports security and authentication, developer credentials, content and data service management, user and group management, and site administration. A portal can be hosted in Esri's infrastructure or your own infrastructure.Learn more. It contains the attributesAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more of the original feature service, which can be accessed to style layers in your application. Find the original feature service in your portalArcGIS portal, also known as a portal, is a website with applications and tools that can be used to create, manage, access, and share geospatial content and data. It supports security and authentication, developer credentials, content and data service management, user and group management, and site administration.

1. Go to the item pageAn item page is a web page in ArcGIS Online or the developer dashboard used to access and manage the properties for an item and the content it references such as a web map, hosted layer, or file.Learn more for the Santa Monica Mountains Parcels vector tile layerA vector tile layer is a data layer used to access and display tiled data and its corresponding styles.Learn more.

2. Under Details, find the Created from property. Follow the link to view the item page for the original feature layerA hosted feature layer is a hosted layer (item) in a portal that is used to manage the properties and settings of a spatially-enabled feature layer in a feature service.Learn more, Santa_Monica_Mountains_Parcels.

3. Click the Data tab to view the layer's featuresA feature is a single record, also known as a row, that represents a real-world entity. It typically contains a geometry (point, multipoint, polyline, or polygon) and attributes but it can also contain just attributes.Learn more and attributesAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more. Each feature represents a land parcel and has attributes such as an address, use code, and number of square feet.

4. Review the values of the UseType field. You will use this field to style vector tiles in your application.

Set up authentication

Set developer credentials

Use the API key or OAuth developer credentialsDeveloper credentials are a type of item in a portal that contains parameters for authentication. There are two types of developer credentials: API key credentials and OAuth credentials.Learn more so your application can access ArcGIS servicesA service, also known as an ArcGIS service, is software that supports an ArcGIS REST API and provides geospatial functionality or data. A service can be hosted by Esri or in ArcGIS Enterprise.Learn more.

Add a vector tile layer

Use the VectorTileLayer class from Esri Leaflet Vector to add data from the Santa Monica Mountains Parcels vector tile serviceA vector tile service is a data service that provides access to vector tile data and a style definition.Learn more to your application.

1. Create a VectorTileLayer and set the url to the URL of the Santa Monica Mountains Parcels vector tile service. Add it to the map.

Add an outline layer

Add another style layer to the MapLibre style object to display parcel outlines.

1. Add a line layer to the list of layers in the style object. Set the source to esri and the source-layer to Santa_Monica_Mountains_Parcels to reference the vector tile service.
