The GeoEnrichment service provides global demographic data for 170 countries and regions. To get globally available information, you use the Key data collection, which returns information for the total population, total households, average household size, and total population for males and females for a study area.
In this tutorial, you use ArcGIS REST JS to access the GeoEnrichment service and display global data for Eastern Europe.
Prerequisites
You need an ArcGIS Location Platform or ArcGIS Online account.
Steps
Create a new pen
- If you are using the CDN libraries, to get started.
Get an access token
You need an access token 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 > Data enrichment
- Privileges:
-
Copy the API key access token to your clipboard when prompted.
-
In CodePen, update the
accessvariable to use your access token.Token Use dark colors for code blocks Copy const accessToken = "YOUR_ACCESS_TOKEN"; const authentication = arcgisRest.ApiKeyManager.fromKey(accessToken);
To learn about the other types of authentication available, go to Types of authentication.
Make the request
You can copy and paste the code below, following the steps to make a request to the GeoEnrichment service.
-
Reference the ArcGIS REST JS libraries either through CDN, ES Modules, or Node JS.
-
- Set the
accesswith an API key access token from API key credentials.Token
- Set the
-
Define the parameters needed for the request. To return global data, set the
dataparameter toCollections [".Key Global Facts"] -
Call the Geoenrichment service and handle the results.
