Query point location for all exposure

[tomalrussell]

For a given location - which may be a current or future infrastructure asset location - I would like to know all the hazards which may affect it.

• Do any hazards have no effect on the location? In that case, report no exposure.
• What are the depths/wind speeds at all return periods? Line graph with 1/return period on x-axis, depth on y-axis.
• What are the likelihoods of extremes, from an event set? Histogram of depths.

---

Implementation notes - may be an API call rather than pushing all data client side:

GET /exposure/rp?lat=0.00&lng=0.00

[
  {
    "hazard": "coastal", 
    "exposure": [0,0,0,1,2], 
    "return_period": [5,10,50,100,250] 
  }
]

^ exposure and return period entries correspond

GET /exposure/events?lat=0.00&lng=0.00

[
  {
    "hazard": "coastal", 
    "events": [2.3,7,2.3]
  }
]

^ events is list of non-zero depths from event set
