Find nearby places and details

Learn how to find places around a location with a keyword search, then get detailed place information.

A nearby search finds places within a given radius of a location using the places service. The location typically represents a point on a map or the geolocation of a device.

To perform a nearby search, you use the places package from ArcGIS REST JS. With the results of the search, you can make another request to the service and return place attributes including the name, categories, ratings, and store hours.

In this tutorial, you use ArcGIS REST JS to perform a nearby search to find points of interest and return all available attributes associated with a place. The tutorial includes starter code that uses Calcite components to create a basic search interface.

Prerequisites

Steps

Get the starter code

To get started, . It contains the Calcite Components necessary to create this application, as well as an initial Leaflet map.

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.

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 apiKey to use your key. Update cesiumAccessToken to use your Cesium ion access token.

Use dark colors for code blocks
      const apiKey = "YOUR_API_KEY";

      Cesium.ArcGisMapService.defaultAccessToken = apiKey;

      const cesiumAccessToken = "YOUR_CESIUM_ACCESS_TOKEN";

      Cesium.Ion.defaultAccessToken = cesiumAccessToken;

      const arcGisImagery = Cesium.ArcGisMapServerImageryProvider.fromBasemapType(Cesium.ArcGisBaseMapType.SATELLITE);

      const viewer = new Cesium.Viewer("cesiumContainer", {

        baseLayer: Cesium.ImageryLayer.fromProviderAsync(arcGisImagery),

      });

    });

Set the search category

To perform a place search, you typically need a category ID. Each category ID corresponds to a unique category of place, such as "Chinese Restaurants" (13099) or "Sports and Recreation" (18000). A Calcite category selector is included in the . It includes the default top-level categories as selectable options.

Declare global variables to track the active place category and clicked location. Set the active category to 16000, which corresponds to the Landmarks and Outdoors category of places.

    });
Expand

Set the search area

A nearby search is defined by a user location and a radius. The places service will search for points of interest near the provided location within the search radius. Add a click handler to set the user location, then draw a circle around that point to represent the search radius.

Add a reference to Turf.js, which will be used to visualize the search extent.
