is websocket good for building geolocalized mobile applications?

Say that I have to build a geolocalized app. What it will happen is that:
thounsands of users will be using it at the same time
while the user will move around the city, will send his geo-location to
the app. Then, based on that location, the app will send back an array of
informations, update the screen and even, probably, a (google) map
So say, if there are 10000 users connected at the same time, all moving
around, there will be really a lot of requests to the app.
I'm doing a little research about the best tecnologies to implement, and I
found that maybe using a websocket would be a good choice. Is that true?
They say that websockets are good for chats, games and sports:
Multiplayer online games
Chat applications
Live sports ticker
Realtime updating social streams
Are they ALSO good for the type of app I'd like to build?
