Tutorial: Enrich data

Learn how to add demographic and local facts data to hosted feature layers using the Map Viewer, ArcGIS APIs, and the GeoEnrichment service.

Esri Tapestry Segmentation data for the United States

GeoEnrichment is the process of discovering and adding demographic and local facts data to feature data. To enrich data, you choose from thousands of data variables grouped into categories such as population, age, income, housing, and spending, and then use the Map Viewer, GeoEnrichment service, or spatial analysis service to enrich the data. The additional data can be used to reveal demographic, socioeconomic, and other financial and business-related patterns for a geographic area.

In this tutorial, you use the Map Viewer, ArcGIS API for Python, ArcGIS REST JS, and the ArcGIS REST API to add demographic information to hosted feature layers using the EnrichLayer operation from the spatial analysis service.

Prerequisites

Steps

The easiest way to enrich data is to use the Map Viewer. The main requirement is that you have a hosted feature layer available to perform the enrichment analysis.

The general steps to use the Map Viewer include the following:

Sign in to your portal:
- ArcGIS Location Platform: Go to https://location.arcgis.com > My portal.
- ArcGIS Online: Go to https://www.arcgis.com/home/signin.html.
- ArcGIS Enterprise: Learn more at ArcGIS Enterprise > Use > Get started > Access.
Go to Map Viewer.
In the Content (dark) toolbar, click Add to select and add the hosted feature layers that you want to enrich.
In the Settings (light) toolbar, click Analysis > Tools > Enrich Layer.
For the Input features, select the analysis layer to enrich.
Click + Variable to select the data variables you want and then click Select.
Specify an Output name then click Run.
View the results on the map.

Code examples

The examples below show you how to enrich different types of hosted feature layers with different data variables. The analysis ranges from country to city scale.

Enrich countries with population data

In this example, you add population data to countries in the World Countries (Generalized) hosted feature layer. The data variable used is Total Population.

Results

The results are returned in a new hosted feature layer containing census blocks enriched with the housing data.

Enrich layers analysis revealing home value, renter, and household income data.

Enrich tessellations with local business data

In this tutorial, you add local business data related to coffee consumers and spending within the Portland City Boundary hosted feature layer. This data could be used to find the areas best suited to support a new coffee bean roasting business.

To subdivide areas within the Portland City Boundary, you will create a hexagon bin tessellation. After creation, you will enrich the bins with coffee consumer and spending information. The data variables you will use are:

2024 Coffee (average spending)
2024 HH Spent $100-$149 in Average Week at Food Stores
2024 Shopped at Costco Warehouse or Club Store Last 6 Mo
2024 Shopped at Walmart Neighborhood Market Grocery Store Last 6 Mo

Steps

Part 1: Copy the web map

Go to the Enrich data tutorial web map and click Sign in.
Verify that you the following layer by toggling the visibility on and off.
- Portland Boundary
Click Save > Save As > Save Map to save a copy.

Part 2: Generate hexagon bins

Steps to use the Map Viewer

Steps to use ArcGIS Python, REST JS, and REST APIs

In the Settings (light) toolbar, click Analysis > Tools > Generate Tessellations.
Set the following parameters:
- Bin shape type: Hexagon
- Bin size measurement: Area
- Bin size: 1
- Bin size units: Square Miles
- Extent layer: Portland boundary.
- Only keep intersecting tessellations: true (checked).
Set the Output name to: Portland one mile hexbins.
