Code sample

Python

Before trying this sample, follow the Python setup instructions in the BigQuery Quickstart Using Client Libraries. For more information, see the BigQuery Python API reference documentation.

import geojson
from google.cloud import bigquery

bigquery_client = bigquery.Client()

# This example uses a table containing a column named "geo" with the
# GEOGRAPHY data type.
table_id = "my-project.my_dataset.my_table"

# Use the python-geojson library to generate GeoJSON of a line from LAX to
# JFK airports. Alternatively, you may define GeoJSON data directly, but it
# must be converted to a string before loading it into BigQuery.
my_geography = geojson.LineString([(-118.4085, 33.9416), (-73.7781, 40.6413)])
rows = [
    # Convert GeoJSON data into a string.
    {"geo": geojson.dumps(my_geography)}
]

#  table already exists and has a column
# named "geo" with data type GEOGRAPHY.
errors = bigquery_client.insert_rows_json(table_id, rows)
if errors:
    raise RuntimeError(f"row insert failed: {errors}")
else:
    print(f"wrote 1 row to {table_id}")
