LineString | Geospatial Types | Teradata Package for Python - LineString - Teradata Vantage

This function enables end user to create an object for the single LineString using the coordinates. It allows user to use the same in GeoDataFrame manipulation and processing using any Geospatial function.

Optional argument:

Example 1: Create a LineString in 2D, using x and y coordinates

>>> from teradataml import Point, LineString

>>> 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

>>> from teradataml import Point, LineString

>>> 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(l2.coords)
[(0, 0, 1), (0, 1, 3), (1, 3, 6), (3, 3, 6), (3, 6, 1), (6, 3, 3), (3, 3, 0)]

Example 3: Create a LineString using Point geometry objects

>>> from teradataml import Point, LineString

# 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

>>> from teradataml import Point, LineString

>>> 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

>>> from teradataml import Point, LineString

>>> le = LineString()

>>> # Print the coordinates.
>>> print(le.coords)
EMPTY
