Note: this was suggested in the 2020-09-08 EUROMAMMAL technical call

In addition to cam_height and cam_angle, it would be useful to know the camera trap orientation/direction (wind direction).

The EUROMAMMAL table suggests north; west; south; east, but I would suggest a (decimal) degrees from north (e.g. south = 180). The same is used for heading in Movebank.

My proposal:

{
  "name": "orientation",
  "type": "number", # Or integer
  "format": "default",
  "description": "The direction of the camera in decimal degrees clockwise from north (0 = north, 90 = east, 180 = south, 270 = west).", # Or degrees
  "example": "311.2", # Or integer
  "constraints": {
    "required": false,
    "minimum": 0,
    "maximum": 360
   }
}

This term is also suggested by @Tim-Hofmeester in #55.
