- DESCRIPTION:
Returns the maximum X coordinate of a Geometry value.
PARAMETERS:
None
SUPPORTED GEOMETRY TYPES:
All Geometry types.
RAISES:
TypeError, ValueError, TeradataMlException
RETURNS:
GeoDataFrameColumn
Resultant column contains a NULL, if the Geometry is an empty set.
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.
gdf = GeoDataFrame("sample_shapes")
gdf = gdf.select(["skey", "polygons", "linestrings"])
gdf
# Example 1: Get the maximum X coordinate of all Polygon geometries in column 'polygons'.
gdf.assign(res=gdf.polygons.max_x)
# Example 2: Filter the rows where maximum X coordinate value of geometry in column 'polygons' is greater than 20.
gdf[gdf.polygons.max_x > 20]
