- teradataml.geospatial.geodataframe.GeoDataFrame.contains = contains(self, geom_column)
- DESCRIPTION:
Tests if a Geometry value spatially contains another Geometry value.
Note:
* Using a geospatial index can greatly improve the performance of
queries that use this method.
PARAMETERS:
geom_column:
Required Argument.
Specifies the other Geometry value.
Types: str, ColumnExpression, GeometryType
SUPPORTED GEOMETRY TYPES:
All Geometry types except geometry collections.
Note:
This method can be called on 3D geometries (those that include Z
coordinates). However, the Z coordinate is ignored in method
calculations.
RAISES:
TypeError, ValueError, TeradataMlException
RETURNS:
GeoDataFrame
Resultant column contains:
* 1, if the input geometry contains other geometry
* 0, if the input geometry does not contain other geometry
EXAMPLES:
from teradataml import GeoDataFrame, load_example_data
from teradataml import Point, LineString, Polygon
# Load example data.
load_example_data("geodataframe", "sample_shapes")
# Create a GeoDataFrame.
geodf = GeoDataFrame("sample_shapes")
print(geodf)
# Let's select only few columns from GeoDataFrame.
points_lines = geodf.select(["skey", "points", "linestrings"])
# Example 1: Check if the ST_Linestring/ST_MultiLinestring type geometries in column
# 'linestrings' contains the geometries in column 'points' of type ST_Point/ST_MultiPoint.
# First, set the geometry property of GeoDataFrame to point to 'linestrings' column.
points_lines.geometry = points_lines.linestrings
# Pass the GeoDataFrameColumn object of 'points' columns as input to "geom_column" argument.
points_lines.contains(geom_column=points_lines.points)
# Example 2: Check if the ST_Linestring/ST_MultiLinestring type geometries in column
# 'linestrings' contains the geometry specified by a GeometryType object - Point.
# First, set the geometry property of GeoDataFrame to point to 'points' column.
points_lines.geometry = points_lines.points
# Create a Point GeometryType object with co-ordinates 1 and 3.
point1 = Point(1, 3)
# Pass the Point() GeometryType object as input to "geom_column" argument.
points_lines.contains(geom_column=point1)
