Google Maps has a wealth of useful features. Besides showing our location, it plans routes and provides real-time directions. It also gives traffic information, restaurant reviews, and lots more. Google has just unveiled its latest tool. Users can now click on its Air Quality Index (AQI) before going on a picnic, camping trip or hike. Google's blog stated: "When you're visiting a new place or planning outdoor activities, it can be helpful to know the air quality conditions – like whether it's unusually smoggy." It added that its new AQI is, "a measure of how healthy (or unhealthy) the air is."

The new feature is a "layer" on Google Maps. Users tap on the same Layers icon as they do to select the satellite or street view modes. There will be an option to see air quality information. Google said: "We collaborate closely with partners in the weather and air quality space to [provide] helpful and authoritative information.…We hope these tools help you feel safe and informed." The AQI will also provide updated information on the health impact of air quality. In addition, there is a "wildfires near me" feature to alert and advise people on the status of fires.
