Instance Attribute Details
#lat_lng ⇒ Google::Apis::VisionV1::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)
