Activies UI

[rjarvi]

Activites UI component

functionality (admin only)

• for users, show "midpoint has been selected, squad leader is selecting an activity"
• for admins, show list of locations sorted (?) distance from location
• users can select a squad goal and set it, triggering selection endpoint
  • should include websockets and firebase notifications

notes for later:
may have to calculate distance manually on backend, example from chat

from math import radians, sin, cos, sqrt, atan2

def haversine(lat1, lon1, lat2, lon2):
    R = 6371000  # meters
    dlat, dlon = radians(lat2 - lat1), radians(lon2 - lon1)
    a = sin(dlat/2)**2 + cos(radians(lat1)) * cos(radians(lat2)) * sin(dlon/2)**2
    return R * 2 * atan2(sqrt(a), sqrt(1 - a))
