Incorrect altitude in example

[evanp]

The example for altitude in the vocabulary document is:

{
  "@context": "https://www.w3.org/ns/activitystreams",
  "type": "Place",
  "name": "Fresno Area",
  "altitude": 15.0,
  "latitude": 36.75,
  "longitude": 119.7667,
  "units": "miles"
}

This is confusing, since the highest point on earth, Mt. Everest, has an altitude of about 5mi.

This is probably a copy-and-paste error; the example for Place defines the Fresno area with a radius of 15 miles.

An accurate altitude would be 94m or 0.06 miles or 308ft. Since feet is the idiomatic measurement of altitude in the USA, that's probably the right one to use.
