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 Developer or ArcGIS Online account to access the developer dashboard and create an API key .
