- teradataml.geospatial.geodataframe.GeoDataFrame.alias = alias(self, alias_name)
- DESCRIPTION:
Method to create an aliased teradataml GeoDataFrame.
Note:
* This method is recommended to be used before performing
self join using GeoDataFrame's join() API.
PARAMETERS:
alias_name:
Required Argument.
Specifies the alias name to be assigned to a teradataml GeoDataFrame.
Types: str
RETURNS:
teradataml GeoDataFrame
EXAMPLES:
>>> load_example_data("geodataframe", "sample_shapes")
>>> gdf = GeoDataFrame("sample_shapes")
>>> geo_df = gdf.select(["skey", "points", "linestrings"])
>>> display.geometry_column_length = 100
# Example 1: Create an alias of teradataml GeoDataFrame.
>>> geo_df2 = geo_df.alias("rhs_gdf")
# Print aliased GeDataFrame.
>>> geo_df2
