Find nearby places and details

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

Find nearby places and details using API key authentication

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. You also use Calcite components to create a basic search interface.

Prerequisites

Steps

Get the starter app

Select a type of authentication below and follow the steps to create a new application.

You can choose one of the following to create a new CodePen:

  • Option 1: Complete the Display a scene tutorial; or,
  • Option 2: Start from the Display a scene tutorial .

Set up authentication

Create developer credentials in your portal for the type of authentication you selected.

Create a new API key credential with the correct privileges to access the resources used in this tutorial.

  1. Go to the Create an API key tutorial and create an API key with the following privilege(s):
    • Privileges
      • Location services > Basemaps
      • Location services > Places
  2. Copy the API key access token to your clipboard when prompted.

Set developer credentials

Use the API key or OAuth developer credentials created in the previous step in your application.

  1. Add <script> elements in the HTML <body> and create an accessToken variable to store your access token. Set YOUR_ACCESS_TOKEN with the access token you previously copied from your API key credentials.

Get a Cesium ion access token

All Cesium applications must use an access token provided through Cesium ion. This token allows you to access assets such as Cesium World Terrain in your application.

  1. Go to your Cesium ion dashboard to generate an access token. Copy the key to your clipboard.

  2. Create a cesiumAccessToken variable and replace YOUR_CESIUM_ACCESS_TOKEN with the access token you copied from the Cesium ion dashboard.

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).

  1. 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.

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.

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

Find places near a point

Once a location and category have been set, make a request to the places service to find places near a point.

  1. Define a new function showPlaces. Use the ArcGIS REST JS findPlacesNearPoint function to submit a request to the places service. Pass the searchRadius, userLocation, and activeCategory, as well as your authentication object.

Display results in a list

To show more information about each place, you will also display place results as an element in a Calcite list. Each element in the list should display a place name, category, and distance from the clicked location.

  1. Create a new calcite-list-item element to display place information. Set the item properties to display the place name, category, and distance from the user's click. Add the element to the list of results.

  3. Run the app. Clicking on the map should perform a place search and display results as markers on the map. Result names and categories should display in the results panel to the left.

Get place details

The user of your application should be able to click on a result in the panel in order to see more information about it. Perform an arcgisRest.getPlace request to obtain detailed attributes about a specific point of interest.

  1. Create a new function getDetails. When a result is clicked, call getDetails and pass the entity associated with the result.
