Workflow: Create a map tile service for an app

In this workflow, you will learn how to create, manage, and access a map tile service in your portal. The process involves importing an existing dataset to create a hosted feature layer and a feature service, managing the service, publishing the map tile service, setting the security level, and then displaying the data in an application.

Prerequisites

You need an account for ArcGIS Location Platform, ArcGIS Online, or ArcGIS Enterprise to create hosted data services. If you need an account, go to Get started.

The Scripting APIs sections of this tutorial requires you to implement authentication. To learn more about the different types of authentication, go to Security and authentication.

Steps

Download the data

For this workflow, you will use the Santa Monica elevation contours dataset.

In your web browser, go to the Santa Monica elevation contours item.
Click the Download button to download the zip file locally. Do not unzip this file.

Create a feature layer

Before you create a map tile layer, you need to create a feature layer.

To create a feature layer in a feature service, you need to upload data into ArcGIS. You can use data management tools or scripting APIs.

Data management tools

Import the shapefile using a data management tool.

In your web browser, go to ArcGIS.com and sign in to your portal with your ArcGIS Location Platform account.

In the top navigation bar, click Content.
Click New item. To upload the Santa Monica elevation contours Shapefile, you can either:
- Drag and drop the file.
- Or, click Your device and navigate to the file path.
Select Santa_Monica_contours_clipped_export.zip and create a hosted feature layer to publish the file as a hosted feature layer.
In Fields, leave all fields at their default settings and click Next.
In Location settings, leave the default settings and click Next.
Set the following information in the item details pane:
- Title: Santa Monica elevation contours
- Tags: santa, monica, elevation, contours, map tile, service,tutorial
- Summary: City of Santa Monica elevation contours
Click Next to create the new feature layer and feature service.

In your web browser, go to ArcGIS.com and sign in to your portal with your ArcGIS Online account.

In the top navigation bar, click Content.
Click New item. To upload the Santa Monica elevation contours Shapefile, you can either:
- Drag and drop the file.
- Or, click Your device and navigate to the file path.
Select Santa_Monica_contours_clipped_export.zip and create a hosted feature layer to publish the file as a hosted feature layer.
In Fields, leave all fields at their default settings and click Next.
In Location settings, leave the default settings and click Next.
Set the following information in the item details pane:
- Title: Santa Monica elevation contours
- Tags: santa, monica, elevation, contours, map tile, service,tutorial
- Summary: City of Santa Monica elevation contours
Click Next to create the new feature layer and feature service.

In your web browser, go to your ArcGIS Enterprise portal and sign in to your portal with your ArcGIS Enterprise account.

In the top navigation bar, click Content.
Click New item. To upload the Santa Monica elevation contours Shapefile, you can either:
- Drag and drop the file.
- Or, click Your device and navigate to the file path.
Select Santa_Monica_contours_clipped_export.zip and create a hosted feature layer to publish the file as a hosted feature layer.
In Fields, leave all fields at their default settings and click Next.
In Location settings, leave the default settings and click Next.
Set the following information in the item details pane:
- Title: Santa Monica elevation contours
- Tags: santa, monica, elevation, contours, map tile, service,tutorial
- Summary: City of Santa Monica elevation contours
Click Next to create the new feature layer and feature service.

You can use ArcGIS Pro to import Santa Monica elevation contours data.

Unzip the Santa_Monica_contours_clipped_export zip file.
- The zip file contains the OverlayedFeatures.shp file.
Launch ArcGIS Pro.
- Create a new map project.
- A map with World Topographic Map and World Hillshade basemap layers will be created.
In the Map ribbon, click on Add Data > Data and select OverlayedFeatures.shp file.

The OverlayedFeatures.shp file is added as a feature layer to the map.

Scripting APIs

You can also import the shapefile with the ArcGIS API for Python or ArcGIS REST JS. The general steps are as follows:

Import the required libraries.
Implement authentication.
Create and publish a portal item.
Handle the results.

Get an access token

By default, the sharing level of an item is set to Owner and requires an access token, such as an API key to access it in a client-side application. If you have an ArcGIS Location Platform or ArcGIS Online account, you can scope an API key to access private items. You cannot scope an API key to access private items if you have an ArcGIS Enterprise account. Instead, to access private items, you need to generate a token from an OAuth 2.0 workflow.

In your web browser, go to ArcGIS.com and sign in to your portal with your ArcGIS Location Platform account.

Click Content > My Content.
Click the New Item > Developer credentials.
In the Create developer credentials window, select API key credentials. Click Next.

Find the service URL and item ID

To access a hosted layer from an application, you need to be able to identify its ID and URL. If a layer is public, you use the URL or item ID to access it directly with your web browser or any application. If the layer is private, you need to provide an access token.

If you are using ArcGIS Maps SDKs:

In the item page, click View to access the service. Locate the Service ItemId, which will look something like this:
- Service ItemID: 5fd812155876416997c1a03e841e8821

If you are using open source libraries:

In the item page, scroll down to the bottom of the page to find the Service URL. For example:
- Service URL: https://services3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Santa_Monica_contours_(map_tiles)/MapServer

If you are using ArcGIS Maps SDKs:

In the item page, click View to access the service. Locate the Service ItemId, which will look something like this:
- Service ItemID: 5fd812155876416997c1a03e841e8821

If you are using open source libraries:

In the item page, scroll down to the bottom of the page to find the Service URL. For example:
- Service URL: https://services3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Santa_Monica_contours_(map_tiles)/MapServer

If you are using ArcGIS Maps SDKs:

In the item page, click View to access the service. Locate the Service ItemId, which will look something like this:
- Service ItemID: 5fd812155876416997c1a03e841e8821

If you are using open source libraries:

In the item page, scroll down to the bottom of the page to find the Service URL. For example:
- Service URL: https://{host}/{webadaptor}/rest/services/Hosted/{serviceName}/MapServer

Display tiles

To display map tiles from the Santa Monica elevation contours map tile service, you need to use a client-side mapping API such as an ArcGIS Maps SDK or open source library. Typically, you use a client-side tile layer class and set the service URL and layer index to access the feature layer.

Select an ArcGIS Maps SDK or open source library.
In the layer item page, find the service URL and layer index or the item ID.
In the code, set the service URL to the client-side URL parameter or the item ID to the portal item parameter.
Add the layer to the map.
