In this section we provide a set of examples that showcase how to leverage the functions of our to unlock advanced spatial analyses in your data warehouse platform. They cover a broad range of use cases with methods for data transformations, enrichment, spatial indexing in Quadbin and H3, statistics, clustering, spatial data science methods and more.
Spacetime hotspot classification: Understanding collision patterns
Spatiotemporal analysis is crucial in extracting meaningful insights from data that possess both spatial and temporal components. This example shows how to identify and classify space-time hot and coldspots using the Analytics Toolbox.
STATISTICS
Time series clustering: Identifying areas with similar traffic accident patterns
Spatiotemporal analysis plays a crucial role in extracting meaningful insights from data that possess both spatial and temporal components. This example shows how to cluster geolocated time series using the Analytics Toolbox.
STATISTICS
Applying GWR to understand Airbnb listings prices
Geographically Weighted Regression (GWR) is a statistical regression method that models the local (e.g. regional or sub-regional) relationships between a set of predictor variables and an outcome of interest. Therefore, it should be used in lieu of a global model in those scenarios where these relationships vary spatially. In this example we are going to analyze the local relationships between Airbnb's listings in Berlin and the number of bedrooms and bathrooms available at these listings using the GWR_GRID procedure.
STATISTICS
Analyzing signal coverage with line-of-sight calculation and path loss estimation
Coverage analysis is fundamental for assessing the geographical areas where a network's signal is available and determining its quality. This guide shows how to use CARTO telco functionality in the Analytics Toolbox for signal coverage analysis.

Measuring merchant attractiveness and performance in CPG with spatial scores
In the CGP industry, consolidating diverse data sources into a unified score becomes crucial for businesses to gain a comprehensive understanding of their product's potential in different locations. In this example, you will learn how to create spatial scores to both understand how attractive each merchant is and to identify how well they are performing when it comes to selling a product.
CPG
Find twin areas of your top performing stores
The Twin Areas analysis can be used to build a similarity score with respect to an existing site (e.g. the location of your top performing store) for a set of target locations, which can prove an essential tool for Site Planners looking at opening, relocating, or consolidating their retail network. In this example we select as potential origin locations the locations of the top 10 performing liquor stores in 2019 in Iowa, US from the publicly available Liquor sales dataset to find the most similar locations in Texas, US.

Analyzing weather stations coverage using a Voronoi diagram
Voronoi diagrams are a very useful tool to build influence regions from a set of points and the Analytics Toolbox provides a convenient function to build them. An example application of these diagrams is the calculation of the coverage areas of a series of weather stations. In the following query we are going to calculate these influence areas in the state of New York.

A NYC subway connection graph using Delaunay triangulation
Providing a good network connection between subway stations is critical to ensure an efficient mobility system in big areas. Let's imagine we need to design a well-distributed subway network to connect the stations of a brand-new subway system. A simple and effective solution to this problem is to build a Delaunay triangulation of the predefined stations, which ensures a good connection distribution.

Creating simple tilesets
We provide a set of examples that showcase how to easily create simple tilesets allowing you to process and visualize very large spatial datasets stored in BigQuery. You should use it if you have a dataset with any geography type (point, line, or polygon) and you want to visualize it at an appropriate zoom level.
TILER
Creating spatial index tilesets
We provide a set of examples that showcase how to easily create tilesets based on spatial indexes allowing you to process and visualize very large spatial datasets stored in BigQuery. You should use this procedure if you have a dataset that contains a column with a spatial index identifier instead of a geometry and you want to visualize it at an appropriate zoom level.
TILER
Creating aggregation tilesets
We provide a set of examples that showcase how to easily create aggregation tilesets allowing you to process and visualize very large spatial datasets stored in BigQuery. You can use this procedure if you have a point dataset (or anything that can be converted to points, such as polygon centroids) and you want to see it aggregated.

Using raster and vector data to calculate total rooftop PV potential in the US
In this example, you will learn how to easily load raster data into BigQuery, and then combine it with vector data using the raster module of the Analytics Toolbox. To illustrate this we will compute the total rooftop photovoltaic power (PV) potential across all buildings in the US.
