Tutorial: Search for an address

Learn how to find an address or place.

Find the location of addresses with the geocoding service using API key authentication

Geocoding is the process of converting address or place text to a location. The geocoding service provides address and place geocoding and reverse geocoding.

In this tutorial, you use ArcGIS REST JS to access the geocoding service. You use a simple input control to accept text and a button to execute a search for an address or place. When an address or place is located, a pop-up will appear with the name, location, and address, and the view will pan to it.

Prerequisites

An ArcGIS Location Platform or ArcGIS Online account.

Steps

Get the starter app

Select a type of authentication below and follow the steps to create a new application.

You can choose one of the following to create a new CodePen:

Option 1: Complete the Display a scene tutorial; or,
Option 2: Start from the Display a scene tutorial .

Set up authentication

Create developer credentials in your portal for the type of authentication you selected.

Create a new API key credential with the correct privileges to access the resources used in this tutorial.

Go to the Create an API key tutorial and create an API key with the following privilege(s):
- Privileges
  - Location services > Basemaps
  - Location services > Geocoding
Copy the API key access token to your clipboard when prompted.

Set developer credentials

Use the API key or OAuth developer credentials created in the previous step in your application.

Add <script> elements in the HTML <body> and create an accessToken variable to store your access token. Set YOUR_ACCESS_TOKEN with the access token you previously copied from your API key credentials.

  <script>

    /* Use for API key authentication */

Set the defaultAccessToken included with Cesium to authenticate requests to the ArcGIS services used in this tutorial.

In both the index.html and callback.html files, set the properties of clientId and redirectUri with the client ID and redirect URL of your OAuth credentials.

index.html
Use dark colors for code blocks
    /* Use for user authentication */
    const clientId = "YOUR_CLIENT_ID"; // Your client ID from OAuth credentials
    const redirectUri = "YOUR_REDIRECT_URI"; // The redirect URL registered in your OAuth credentials
    const session = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
      clientId,
      redirectUri,
      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    })

    const accessToken = session.token;

callback.html
Use dark colors for code blocks
    arcgisRest.ArcGISIdentityManager.completeOAuth2({
      clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
      redirectUri: "YOUR_REDIRECT_URI", // The redirect URL registered in your OAuth credentials
      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    })

Run the app and ensure you can sign in successfully.

If you are unable to sign in, make sure you have the correct redirect URL and port. This URL varies based on your application and typically takes the format of https://<server>[:port]/callback.html or http://my-arcgis-app:/auth. For example, if you are running an application on http://127.0.0.1:5500/, set http://127.0.0.1:5500/callback.html as your redirect URL in the index.html and callback.html file and your developer credential. They all have to match!

Set the defaultAccessToken included with Cesium to authenticate requests to the ArcGIS services used in this tutorial.

index.html
Use dark colors for code blocks
    Cesium.ArcGisMapService.defaultAccessToken = accessToken;

Get a Cesium ion access token

All Cesium applications must use an access token provided through Cesium ion. This token allows you to access assets such as Cesium World Terrain in your application.

Go to your Cesium ion dashboard to generate an access token. Copy the key to your clipboard.

Create a cesiumAccessToken variable and replace YOUR_CESIUM_ACCESS_TOKEN with the access token you copied from the Cesium ion dashboard.

Use dark colors for code blocks
  <script>

    /* Use for API key authentication */
    const accessToken = "YOUR_ACCESS_TOKEN";

    // or

    /* Use for user authentication */
    // const session = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
    //   clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
    //   redirectUri: "YOUR_REDIRECT_URI", // The redirect URL registered in your OAuth credentials
    //   portal: "YOUR_PORTAL_URL" // Your portal URL
    // })

    // const accessToken = session.token;

    Cesium.ArcGisMapService.defaultAccessToken = accessToken;

    const cesiumAccessToken = "YOUR_CESIUM_ACCESS_TOKEN";

  </script>

Configure Cesium.Ion.defaultAccessToken with the Cesium access token to validate the application.

    //   portal: "YOUR_PORTAL_URL" // Your portal URL
    // })

    // const accessToken = session.token;

    Cesium.ArcGisMapService.defaultAccessToken = accessToken;

    const cesiumAccessToken = "YOUR_CESIUM_ACCESS_TOKEN";

    Cesium.Ion.defaultAccessToken = cesiumAccessToken;
