Find places in a bounding box

Learn how to perform a text-based search to find places within a bounding box.

A bounding box search finds places within an extent using the places service. An extent typically represents the visible area of a map. To perform a bounding box 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 such as street address and telephone number.

In this tutorial, you use ArcGIS REST JS to perform a bounding box search based on the visible extent on the map and return details about each place. It includes starter code that uses Calcite components to create a basic search interface.

Prerequisites

Steps

Get the starter code

1. To get started, use this CodePen. It contains the Calcite Components necessary to create this application, as well as a blank 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.

1. Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial.

2. In CodePen, update apiKey to use your key.

Add event listeners

The starter code provided for this tutorial includes a basic user interface with a text input and category buttons. Add event listeners to this interface to make requests to the places service on when they are clicked.

1. Create a showPlaces function to make requests to the places service.

Display results

The response from the places service will contain a list of place results. Each result will include a place's x/y coordinates, name, category, and unique ID.

1. Create an empty Vector layer to store service results. When a new request is made, clear the data in the layer.

5. Run the app. When you click a category button or search for a phrase, the map should display a set of points representing place results.

Configure a popup

The user of your app should be able to click on a place result to view more information about that place. Create a popup that will display when the user clicks on a place.

1. Create a Popup and add it to your map as an overlay. Hide the popup when a new request is made.

Get place address and phone number

You can access more information about a place using the unique placeId associated with it. Perform a subsequent request to the places service to get the street address and phone number of a clicked POI.

1. Use the ArcGIS REST JS getPlaceDetails function to get detailed information about a specific place. Pass the placeId associated with the current marker, and set the requestedFields parameter to return the streetAddress and telephone properties.

Run the app

In CodePen, run your code to display the application. The app should display a map with a search control. Upon clicking a button or entering a phrase, place results should appear on the map. Clicking a result will submit another service request to get the place address and phone number.
