Description
This lab demonstrates how to group geospatial data based on their geographic attributes in BigQuery GIS using Python and Jupyter notebooks. The lab uses spatial joins to combine information from two of Google’s public datasets – the zip codes table and the Chicago crimes table – in order to count the number of crimes in each zip code of Chicago by year. In addition, the lab uses the geopandas package in Python to create a choropleth map showing crime hot spots in Chicago.
