Description

This lab introduces the special GEOGRAPHY data type in Google Cloud Platform’s BigQuery GIS serverless data warehouse tool. The lab walks the user through the spatial constructor functions which allow the user to create GEOGRAPHY objects, including points, linestrings, and polygons. The final section covers how users can export GEOGRAPHY objects into other data formats, such as GeoJSON.

Learning Objectives

Upon completion of this lab you will be able to:

  • Interact with BigQuery datasets within Jupyter notebooks
  • Convert geospatial data into a BigQuery GIS GEOGRAPHY data object
  • Export BigQuery GIS GEOGRAPHY objects into other formats

Intended Audience

This lab is intended for:

  • GIS engineers
  • Data engineers dealing with location-based data
  • Developers looking to leverage geospatial information

Prerequisites

You should possess:

  • Basic understanding of relational databases and ANSI SQL
  • Basic understanding of Python
