CARTO Analytics Toolbox Lite

**Introduction to CARTO Platform**

CARTO is the leading Location Intelligence platform for geospatial data analysis, providing advanced tools to visualize, analyze, and gain insights from location data.

As part of the CARTO Location Intelligence platform, this toolbox enhances your geospatial analysis capabilities within Snowflake. By leveraging Snowflake’s cloud data platform, CARTO allows you to seamlessly integrate and process spatial data for various applications, empowering your business with actionable spatial intelligence.

**Analytics Toolbox Lite Overview**

The CARTO Analytics Toolbox Lite is composed of a set of user-defined functions (UDFs) that extend the geospatial capabilities of Snowflake. These functions are categorized into modules based on their functionalities. This package includes a set of open source modules, supporting different spatial indexes and other geospatial operations, like:

- Transformations, like ST_BUFFER to generate a circular area of a given radius from a geography point; or ST_CONCAVEHULL to calculate the minimum (concave) area that covers a set of points.
- H3 based functions beyond Snowflake's native capabilities, like H3_KRING to calculate an area of concentric H3 rings.
- Clustering, like the ST_CLUSTERKMEANS function to calculate clusters of points based on the distance to each other.
- Processing, ST_VORONOIPOLYGONS to generate Voronoi polygons from a set of points.
- Much more foundational capabilities for cloud-native geospatial analysis.

**Advanced Functionality**

For a more advanced set of functions and procedures, such as tiling and raster, please check out our full Analytics Toolbox by visiting [this listing](https://app.snowflake.com/marketplace/listing/GZT0Z4CM1E9M5/carto-carto-analytics-toolbox-platform). The full toolbox includes additional modules like data, http_request, import, geocoding, isolines, routing , raster, retail, statistics, and tiler - you'll find a full list in our [documentation page](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-snowflake/sql-reference).

Please note that accessing the full capabilities of the Analytics Toolbox requires a CARTO platform subscription (carto.com/signup). You can start with a trial to explore all the advanced features and see how CARTO can elevate your spatial data analysis.

**Documentation and Updates**

In our [documentation page](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-snowflake/sql-reference), you'll find a comprehensive list of the available functions, their definitions, and fully working code samples. We regularly include new functionalities, which will be automatically available to you, check out our [release notes](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-snowflake/release-notes) for regular updates about the Analytics Toolbox content and functionality.
