If only 1 additional point:
| |
|RL--x0--|RL--
| |
-180 180|-180
If they are evenly spaced and it crosses the antimeridian:
x0 - L = 180
R - x0 = -180
For example:
Let R = -179.9, x0 = 0.1, L = -179.89
x0 - L = 0.1 - -179.9 = 180
R - x0 = -179.89 - 0.1 ~= -180
This is the same in the case when it didn't cross the antimeridian.
If you have 2 additional points:
| |
|RL--x0--x1--|RL--
| |
-180 180|-180
If they are evenly spaced and it crosses the antimeridian:
x0 - L = 120
x1 - x0 = 120
R - x1 = -240
For example:
Let R = -179.9, x0 = -59.9, x1 = 60.1 L = -179.89
x0 - L = 59.9 - -179.9 = 120
x1 - x0 = 60.1 - 59.9 = 120
R - x1 = -179.89 - 60.1 ~= -240
However, if they are evenly spaced and it didn't cross the antimeridian:
x0 - L = 120
x1 - x0 = 120
R - x1 = 120
From this, we have a delta that is guaranteed to be significantly
large enough to tell the difference reguarless of the direction
the antimeridian was crossed.
However, even though the spacing was even in the source projection, it isn't
guaranteed in the targed geographic projection. So, instead of 240, 200 is used
as it significantly larger than 120 to be sure that the antimeridian was crossed
but smalller than 240 to account for possible irregularities in distances
when re-projecting. Also, 200 ensures latitudes are ignored for axis order handling.

Calling a Proj class instance with the arguments lon, lat will
convert lon/lat (in degrees) to x/y native map projection
coordinates (in meters).
Inputs should be doubles (they will be cast to doubles if they
are not, causing a slight performance hit).
Works with numpy and regular python array objects, python
sequences and scalars, but is fastest for array objects.
Parameters
----------
longitude: scalar or array (numpy or python)
Input longitude coordinate(s).
latitude: scalar or array (numpy or python)
Input latitude coordinate(s).
inverse: bool, default=False
If inverse is True the inverse transformation from x/y to
lon/lat is performed.
radians: bool, default=False
If True, will expect input data to be in radians and will return radians
if the projection is geographic. Otherwise, it uses degrees.
This does not work with pyproj 2 and is ignored. It will be enabled again
in pyproj 3.
errcheck: bool, default=False

Projection of input data.

Projection of output data.
skip_equivalent: bool, default=False
DEPRECATED: If true, will skip the transformation operation

always_xy: bool, default=False
If true, the transform method will accept as input and return as output
coordinates using the traditional GIS order, that is longitude, latitude
for geographic CRS and easting, northing for most projected CRS.
area_of_interest: :class:`pyproj.transformer.AreaOfInterest`, optional
The area of interest to help select the transformation.
authority: str, optional
When not specified, coordinate operations from any authority will be
searched, with the restrictions set in the
authority_to_authority_preference database table related to the
authority of the source/target CRS themselves. If authority is set
to “any”, then coordinate operations from any authority will be
searched. If authority is a non-empty string different from "any",
then coordinate operations will be searched only in that authority
namespace (e.g. EPSG).
accuracy: float, optional
The minimum desired accuracy (in metres) of the candidate
coordinate operations.
allow_ballpark: bool, optional
Set to False to disallow the use of Ballpark transformation
in the candidate coordinate operations. Default is to allow.

x2, y2, z2 = transform(p1, p2, x1, y1, z1)
Transform points between two coordinate systems defined by the
Proj instances p1 and p2.
The points x1,y1,z1 in the coordinate system defined by p1 are
transformed to x2,y2,z2 in the coordinate system defined by p2.
z1 is optional, if it is not set it is assumed to be zero (and
only x2 and y2 are returned). If the optional keyword
'radians' is True (default is False), then all input and
output coordinates will be in radians instead of the default
of degrees for geographic input/output projections.
If the optional keyword 'errcheck' is set to True an
exception is raised if the transformation is
invalid. By default errcheck=False and ``inf`` is returned for an
invalid transformation (and no exception is raised).
If `always_xy` is toggled, the transform method will accept as
input and return as output coordinates using the traditional GIS order,
that is longitude, latitude for geographic CRS and easting,
northing for most projected CRS.
In addition to converting between cartographic and geographic
projection coordinates, this function can take care of datum
shifts (which cannot be done using the __call__ method of the
Proj instances). It also allows for one of the coordinate
systems to be geographic (proj = 'latlong').
x,y and z can be numpy or regular python arrays, python
lists/tuples or scalars. Arrays are fastest. For projections in
geocentric coordinates, values of x and y are given in meters.
z is always meters.

points2 = itransform(p1, p2, points1)
Iterator/generator version of the function pyproj.transform.
Transform points between two coordinate systems defined by the
Proj instances p1 and p2. This function can be used as an alternative
to pyproj.transform when there is a need to transform a big number of
coordinates lazily, for example when reading and processing from a file.
Points1 is an iterable/generator of coordinates x1,y1(,z1) or lon1,lat1(,z1)
in the coordinate system defined by p1. Points2 is an iterator that returns tuples
of x2,y2(,z2) or lon2,lat2(,z2) coordinates in the coordinate system defined by p2.
z are provided optionally.
Points1 can be:
- a tuple/list of tuples/lists i.e. for 2d points: [(xi,yi),(xj,yj),....(xn,yn)]
- a Nx3 or Nx2 2d numpy array where N is the point number
- a generator of coordinates (xi,yi) for 2d points or (xi,yi,zi) for 3d
If optional keyword 'switch' is True (default is False) then x, y or lon,lat
coordinates of points are switched to y, x or lat, lon.
If the optional keyword 'radians' is True (default is False),
then all input and output coordinates will be in radians instead
of the default of degrees for geographic input/output projections.
If the optional keyword 'errcheck' is set to True an
exception is raised if the transformation is
invalid. By default errcheck=False and ``inf`` is returned for an
invalid transformation (and no exception is raised).
If `always_xy` is toggled, the transform method will accept as
input and return as output coordinates using the traditional GIS order,
that is longitude, latitude for geographic CRS and easting, northing
for most projected CRS.
