Place finding is the process of searching for a place name or POI to find its address and location.
In this tutorial, you use the Geocoding service to find coffee shops within a specified location and distance.
Prerequisites
You need an ArcGIS Developer or ArcGIS Online account to access the developer dashboard and create an API key.
Steps
Create a new pen
- If you are using the CDN libraries, to get started.
Get an API Key
To access location services, you need an API key or OAuth 2.0 access token. To learn how to create and scope your key, visit the Create an API key tutorial.
- Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial.
- In CodePen, update
api
to use your key.Key
Make the request
Copy and paste the code below, following the steps to make a request to the Geocoding service.
-
Reference the ArcGIS REST JS libraries either through CDN, ES Modules, or Node JS.
-
Set the
api
with the API key from your dashboard.Key -
Define the parameters needed for the request.
-
Call the Geocoding service and handle the results.
