LatLng

An object representing a latitude/longitude pair. This is expressed as a pair of doubles representing degrees latitude and degrees longitude. Unless specified otherwise, this must conform to the WGS84 standard. Values must be within normalized ranges.

Example of normalization code in Python:

def NormalizeLongitude(longitude):
  """Wraps decimal degrees longitude to [-180.0, 180.0]."""
  q, r = divmod(longitude, 360.0)
  if r > 180.0 or (r == 180.0 and q <= -1.0):
    return r - 360.0
  return r

def NormalizeLatLng(latitude, longitude):
  """Wraps decimal degrees latitude and longitude to
  [-90.0, 90.0] and [-180.0, 180.0], respectively."""
  r = latitude % 360.0
  if r <= 90.0:
    return r, NormalizeLongitude(longitude)
  elif r >= 270.0:
    return r - 360, NormalizeLongitude(longitude)
  else:
    return 180 - r, NormalizeLongitude(longitude + 180.0)

assert 180.0 == NormalizeLongitude(180.0)
assert -180.0 == NormalizeLongitude(-180.0)
assert -179.0 == NormalizeLongitude(181.0)
assert (0.0, 0.0) == NormalizeLatLng(360.0, 0.0)
assert (0.0, 0.0) == NormalizeLatLng(-360.0, 0.0)
assert (85.0, 180.0) == NormalizeLatLng(95.0, 0.0)
assert (-85.0, -170.0) == NormalizeLatLng(-95.0, 10.0)
assert (90.0, 10.0) == NormalizeLatLng(90.0, 10.0)
assert (-90.0, -10.0) == NormalizeLatLng(-90.0, -10.0)
assert (0.0, -170.0) == NormalizeLatLng(-180.0, 10.0)
assert (0.0, -170.0) == NormalizeLatLng(180.0, 10.0)
assert (-90.0, 10.0) == NormalizeLatLng(270.0, 10.0)
assert (90.0, 10.0) == NormalizeLatLng(-270.0, 10.0)
Fields
latitude

double

The latitude in degrees. It must be in the range [-90.0, +90.0].

longitude

double

The longitude in degrees. It must be in the range [-180.0, +180.0].
