- Method resolution order:
- LineString
- GeometryType
- builtins.object
Methods defined here:
- __init__(self, coordinates=None)
- DESCRIPTION:
Enables end user to create an object for the single LineString
using the coordinates. Allows user to use the same in GeoDataFrame
manipulation and processing using any Geospatial function.
PARAMETERS:
coordinates:
Optional Argument.
Specifies the coordinates of a Line. While passing coordinates
for a line, one must always pass coordinates in list of either
two-tuples for 2D or list of three-tuples for 3D.
Argument also accepts list of Point as well instead of tuples.
If coordinates are not passed, an object for empty line is
created.
Types: List of
a. Point geometry objects or
b. two-tuple of int or float or
c. three-tuple of int or float or
d. Mix of any of the above.
RETURNS:
LineString
RAISES:
TeradataMlException, TypeError, ValueError
EXAMPLES:
>>> from teradataml import Point, LineString
# Example 1: Create a LineString in 2D, using x and y coordinates.
>>> l1 = LineString([(0, 0), (0, 20), (20, 20)])
>>> # Print the coordinates.
>>> print(l1.coords)
[(0, 0), (0, 20), (20, 20)]
>>> # Print the geometry type.
>>> l1.geom_type
'LineString'
>>>
# Example 2: Create a LineString in 3D, using x, y and z coordinates.
>>> l2 = LineString([(0, 0, 1), (0, 1, 3), (1, 3, 6), (3, 3, 6),
... (3, 6, 1), (6, 3, 3), (3, 3, 0)])
>>> # Print the coordinates.
>>> print(l1.coords)
[(0, 0), (0, 20), (20, 20)]
>>>
# Example 3: Create a LineString using Point geometry objects.
# Create some Points in 2D, using x and y coordinates.
>>> p1 = Point(0, 20)
>>> p2 = Point(0, 0)
>>> p3 = Point(20, 20)
>>> l3 = LineString([p1, p2, p3])
>>> # Print the coordinates.
>>> print(l3.coords)
[(0, 20), (0, 0), (20, 20)]
>>>
# Example 4: Create a LineString using mix of Point geometry objects
# and coordinates.
>>> p1 = Point(0, 20)
>>> p2 = Point(20, 20)
>>> l4 = LineString([(0, 0), p1, p2, (20, 0)])
>>> # Print the coordinates.
>>> print(l4.coords)
[(0, 0), (0, 20), (20, 20), (20, 0)]
>>>
# Example 5: Create an empty LineString.
>>> le = LineString()
>>> # Print the coordinates.
>>> print(le.coords)
EMPTY
