@amon thanks Amon, our plan was to add layers of security, where people will be in teams and only relative team manager can see teams location. users like Managers as well as team members have to login, without login no access for anyone. places are big and mostly outdoors so like 2 km x 2km area like massive events.

@amon so if there is an issue then security personnel can be monitored and if there is a SOS alarm team can get there asap etc. we are working on DB prototype atm using google maps api and location feature. i wanted to know if there are any open classes readymade we can get to speed up deployment or have more testing done so we dont have to reinvent the wheel.
