Overview

You will learn: how to query demographic and lifestyle information about a place with the ArcGIS REST API.

The ArcGIS World GeoEnrichment Service can get rich social and economic information about a location or area. It provides a queryable database of thousands of demographic, lifestyle, and environmental variables. The data can be used to enrich geographic data with contextual variables for analysis. If you would like to create an application that can find demographic data around a location, you can use the ArcGIS REST API and the enrich operation. You just pass in the location (studyArea) and the search options such as distance and the service returns a set of data facts. To learn more about the types of queries and data that can be discovered for a location, please visit the documentation.

In this tutorial , you will use the ArcGIS REST API to access the ArcGIS World GeoEnrichement Service to query demographic data for the area around a trailhead situated in an urban area to learn more about the surrounding residents.

Before you begin

Install Postman to execute HTTP requests. Go to this tutorial if you need an access token.

Steps

Create a request to access the geoenrichment service

  1. Open Postman and click [+] in the tab bar to create a new request.

  2. In the new tab, set the following:

    • HTTP Method: POST
    • Request URL: https://geoenrich.arcgis.com/arcgis/rest/services/World/geoenrichmentserver/GeoEnrichment/enrich

Add parameters to define the spatial reference and to return geometry

  1. Click on Body and add the following parameters as Key/Value pairs:

    • f: json
    • token: Go to this tutorial if you need an access token.
    • inSR: 4326
    • outSR: 4326
    • returnGeometry: true

Add parameters to define the study area and the distance to search for results

  1. Add the following parameters as Key/Value pairs to specify the areas we would like to study:

    • studyAreas:
      [
        {
          "geometry":{
            "x":-118.09047,
            "y":33.81091
          }
        }
      ]
      
    • studyAreasOptions:
      {
        "areaType":"RingBuffer",
        "bufferUnits":"esriMiles",
        "bufferRadii":[1]
      }
      

Add parameters to define the demographic variables to query

  1. Add the following parameters as Key/Value pairs to specify variables or collections of variables we would like to retrieve:

    • dataCollections: ["KeyGlobalFacts", "KeyUSFacts"]

Execute the requst to get the demographic results

  1. Click Send to run the request.

  2. In the response window, change the view to JSON. It should look something like this:

  3. Find the array of results in the response. Each result will contain a FeatureSet with some key properties:

    • fields: An array of information about each returned variable, including its name, human readable alias, unit and type.
    • geometryType: The type of geometry in the geometry key. Usually this will be esriGeometryPolygon.
    • features: The results of the query. Each feature will have attributes representing the variables that we queried and a geometry representing the shape of the area for those geometries.
