teradataml.geospatial.geodataframe.GeoDataFrame.buffer = buffer(self, distance)
DESCRIPTION:
    Returns all points whose distance from a Geometry value is less than or
    equal to a specified distance.
    Note:
        *  The "distance" argument is measured in the linear units of measure in
          the spatial reference system of the Geometry value.
 
PARAMETERS:
    distance:
        Required Argument.
        Specifies the distance from the geometry value to the buffer.
        Types: float, str, ColumnExpression
 
SUPPORTED GEOMETRY TYPES:
    All Geometry types
    Note:
        This method can be called on 3D geometries (those that include Z
        coordinates). However, the Z coordinate is dropped, and only x and y
        coordinates are returned.
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrame with result column containing Geometry values
 
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 skey and points columns from GeoDataFrame.
    points = geodf.select(["skey", "points"])
 
    # Example 1: Get all the points with distance less than or equal to 2.8 from the geometries
    #            specified in column 'points'
    points.buffer(2.8)
