How to host and manage data


1. Create a hosted layer

You can use tools and APIs, such as ArcGIS Online, the developer dashboard, and the portal service REST API to create and publish a hosted layer.

Explore the three ways to create a new hosted layer:

  1. Import: Upload file(s) with your existing data to create a hosted feature layer.
  2. Create: Define a new empty hosted feature layer.
  3. Convert: Create a new type of hosted layer (data) from an existing hosted feature layer.

2. Manage layer settings

After you create a hosted layer, you can use ArcGIS Online and the developer dashboard to manage both the hosted layer and data service with an item page. You use item pages to set hosted layer properties, data service capabilities, and perform other maintenance operations such as caching, data uploading, exporting, and publishing.

3. Access layer data

Once you set a hosted layer's properties, you can access hosted layer and the data service with client APIs, the REST API, and tools such as Map Viewer. In most cases, you access a layer to display the data on a map.

Data hosting

To get data, you need the service URL for your hosted layer and you can access the layer directly or with a query to the service. The easiest way to find the URL is to go to the item page.

To access feature layer data, you execute a query to request a subset of the features from the feature layer. To learn more, go to Hosted feature layers.
