Twitter lets people add their locations to tweets, while Facebook check-ins and the “share location” Messenger function allow people to track their contacts. Snapchat isn’t the first social media company to allow location tracking. It’s also not possible to share your location with someone who isn’t already your friend on Snapchat, and the majority of interactions on Snapchat take place between close friends.” “Snapchatters can choose exactly who they want to share their location with, if at all, and can change that setting at any time. “The safety of our community is very important to us,” said a Snapchat spokesman, who added that location-sharing is off by default and “completely optional”.

The actionmojis appear on the map when a user shares their location and disappear when they’ve been offline for several hours. So some people will appear in an animated car, for example. The map also incorporates “actionmojis”, a new type of personalized avatar that Snapchat automatically creates by analyzing the user’s location, time of day or speed of travel. If there’s a major event or breaking news taking place that lots of people are documenting on Snapchat, a patch of color will appear on the map identifying the hotspot.
