Find places
Learn how to search for coffee shops, gas stations, restaurants and other nearby places with the geocoding service.
Place finding is the process of searching for a place name or POI to find its address and location. You can use the geocoding service to find places such as coffee shops, gas stations, or restaurants for any geographic location around the world. You can search for places by name or by using categories. You can search near a location or you can search globally.
In this tutorial, you use ArcGIS REST JS to access the geocoding service and find places by place category.
Prerequisites
You need an ArcGIS account to access the developer dashboard and create an API key.
Steps
Create a new pen
- To get started, either complete the Display a map tutorial or .
Set the API key
To access location services, you need an API key or OAuth 2.0 access token.
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
apiKeyto use your key.Change line 1 2 3 4 5 6 7 8 9 10// const apiKey = "YOUR_API_KEY"; const basemapEnum = "ArcGIS:Streets"; const map = new mapboxgl.Map({ container: "map", // the id of the div element style: `https://basemaps-api.arcgis.com/arcgis/rest/services/styles/${basemapEnum}?type=style&token=${apiKey}`, zoom: 12, // starting zoom center: [-118.805, 34.027] // starting location [longitude, latitude] });
Add API references
This tutorial uses ArcGIS REST JS for place finding.
- In the
<head>element, add references to the ArcGIS REST JS library.

A navigation basemap layer is typically used in geocoding and routing applications. Update the basemap layer to use ArcGIS:Navigation.
Update the basemap and the map initialization to center on location

Add controls
Use a select element to create the drop-down element. Each category is an option element inside it. The select element needs to have absolute positioning in order to appear in front of the map element.
Add a select control, with options for "Coffee shop", "Gas station", "Food", "Hotel", "Parks and outdoors". Use inline styling to position the control.
The option values have special meaning to the geocoding service so ensure the spelling is correct. See the ArcGIS REST API documentation for details.

Call the geocoding service
You can use the arcgisRest.geocode function to retrieve places near a location. Use map.getCenter to obtain the center of the viewport in longitude and latitude.
You will also pass the category selected by the user. Use document.getElementById to get the control, then use its value property.
Create a function called
showPlaces. Inside, create a newarcgisRest.ApiKeyto access the geocoding service. CallarcgisRest.geocode()to set the API key and to call the service endpoint. AlocationwithPlace_addrandPlaceNameinformation will be returned based on thecategoryselected. A maximum of 25 locations will display nearest to the center of the map.Add line. Add line. Add line.

Handle errors
It is good practice to handle situations where there is a problem accessing the service. This could happen due to network disruption or a problem with your API key, for instance.
If there is an exception accessing the geocoding service, alert the user and log the error.

Add a change event handler
To update the map when the user chooses a category, you must add an event handler for the change event on the <select> control.
Update the load event handler to call the
showPlaces()function.Add line. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no" /> <script src="https://api.tiles.mapbox.com/mapbox-gl-js/v1.12.0/mapbox-gl.js"></script> <link href="https://api.tiles.mapbox.com/mapbox-gl-js/v1.12.0/mapbox-gl.css" rel="stylesheet" /> <script src="https://unpkg.com/@esri/arcgis-rest-request@3.0.0/dist/umd/request.umd.js"></script> <script src="https://unpkg.com/@esri/arcgis-rest-geocoding@3.0.0/dist/umd/geocoding.umd.js"></script> <script src="https://unpkg.com/@esri/arcgis-rest-auth@3.0.0/dist/umd/auth.umd.js"></script> <style> html, body, #map { padding: 0; margin: 0; height: 100%; width: 100%; font-family: Arial, Helvetica, sans-serif; font-size: 14px; color: #323232; } .places { position: absolute; top: 20px; left: 20px; } </style> </head> <body> <div id="map"></div> <select id="places-select" style="left: 20px; top: 20px; position: absolute; font-size: 16px; padding:4px 8px;"> <option value="">Choose a category...</option> <option value="Coffee shop">Coffee shops</option> <option value="Gas station">Gas stations</option> <option value="Food">Food</option> <option value="Hotel">Hotels</option> <option value="Parks and Outdoors">Parks and Outdoors</option> </select> <script> const apiKey = "YOUR_API_KEY"; const basemapEnum = "ArcGIS:Navigation"; const map = new mapboxgl.Map({ container: "map", style: `https://basemaps-api.arcgis.com/arcgis/rest/services/styles/${basemapEnum}?type=style&token=${apiKey}`, zoom: 13, center: [-122.4194,37.7749] // San Francisco }); map.once("load", () => { map.addSource("places", { type: "geojson", data: { type: "FeatureCollection", features: [] } }); map.addLayer({ id: "places-circle", source: "places", type: "circle", paint: { "circle-color": "hsla(200, 80%, 80%, 0.7)", "circle-stroke-color": "hsl(200, 80%, 40%)", "circle-stroke-width": 1, "circle-radius": 3 } }); map.addLayer({ id: "places-text", source: "places", type: "symbol", layout: { "text-field": ["get", "PlaceName"], "text-font": ["Arial Bold"], "text-variable-anchor": ["left","right"], "text-justify": "left", "text-radial-offset": 0.5 }, paint: { "text-color": "hsl(200, 80%,40%)", "text-halo-color": "white", "text-halo-width": 2 } }); showPlaces(); }); function showPlaces() { const authentication = new arcgisRest.ApiKey({ key: apiKey }); const category = document.getElementById("places-select").value; if (!category) { return; } arcgisRest .geocode({ authentication, outFields: "Place_addr,PlaceName", params: { category, location: map.getCenter().toArray().join(","), maxLocations: 25 } }) .then((response) => { map.getSource("places").setData(response.geoJson); }) .catch((error) => { alert("There was a problem using the geocoder.

When you choose a place category, circles should be shown for places.
Display place labels
You can show the name of each location by using a symbol layer with text properties.
In the load handler, add a
symbollayer.It is important to use a font whose glyphs are present within the map style. This style contains several variants of
Arial, which makes that a safe choice.By default, Mapbox GL JS centers text labels over their center point. Since there is a circle showing already, it is better to treat the point as the
leftanchor, and also set atext-justifyof `left.When labels are close together, not all will be shown. You could change the default settings of
text-allow-overlapif you want to alter this behavior.For more information about available style properties, see the Mapbox GL JS documentation.

Run the app
In CodePen, run your code to display the map.
When you choose a place category, you should see the name of each place shown as a label, next to a white circle with a blue outline.
