teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.min_x
DESCRIPTION:
    Returns the minimum 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 minimum X coordinate of all Polygon geometries in column 'polygons'.
    gdf.assign(res=gdf.polygons.min_x)
 
    # Example 2: Filter the rows where minimum X coordinate value of geometry in column 'polygons' is greater than 0.5
    gdf[gdf.polygons.min_x > 0.5]
