Get local data

Learn how to access local data, such as spending trends, for the United States with the GeoEnrichment service.

The GeoEnrichment service provides detailed local data for specific countries. Each individual data field is represented by an analysis variable that are organized into data categories such as spending and market behaviors such as 2022 Educational Attainment or 2022 Seen Video Ad at Gas Station Last 30 Days. The data available vary by country and by data provider.

In this tutorial, you use ArcGIS REST JS to access the GeoEnrichment service and display spending trend information for a study area within the United States.

Prerequisites

Steps

Create a new pen

1. To get started, either complete the Display a map tutorial or use this pen.

Set the 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.

1. Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial.

2. In CodePen, update apiKey to use your key.

   const basemapId = "arcgis/streets";
   const basemapURL = `https://basemapstyles-api.arcgis.com/arcgis/rest/services/styles/v2/styles/${basemapId}?token=${apiKey}`;
   olms.apply(map, basemapURL);
   

Add references to ArcGIS REST JS

This tutorial uses ArcGIS REST JS to access the geoenrichment service. It also uses the ol-popup library to display pop-ups.

1. Reference the ArcGIS REST JS and ol-popup libraries.

Add a click event handler

You need a location before calling the GeoEnrichment service. To get a location, you can add a handler to the Map's click event. The click handler will be called with an object containing a Coordinate.

You can change the mouse cursor to a crosshair to make it easier to click precisely. Modify the CSS style of its canvas element to do this.

1. In the <style> , set the mouse cursor style to crosshair.

Execute the query

You pass one or more study areas to arcgisRest.queryDemographicData to specify the location of your query. To query a circular buffer around a point, pass a geometry object with x and y parameters. The default search radius is one mile.

1. Inside the click handler, create a new arcgisRest.ApiKeyManager to access the GeoEnrichment service. Call the service using queryDemographicData. Set the studyAreas parameter to a point geometry made from the event's lngLat property.

Display the results

If the query is successful, the response will contain a results array with a value containing a FeatureSet. The FeatureSet contains attributes such as population within the study area, the number of males and females, and the average household size. To learn more, visit the GeoEnrichment service page.

You will display the results of the query in a pop-up.

1. Before the click handler, create a Popup and save it to a popup variable. Add it to the map with map.addOverlay.
