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.

**CARTO平台简介**

CARTO是领先的地理空间数据分析用位置智能（Location Intelligence）平台，提供高级工具以实现位置数据的可视化、分析与洞察挖掘。

作为CARTO位置智能平台的组成部分，本工具箱可增强你在Snowflake内的地理空间分析能力。依托Snowflake的云数据平台，CARTO能够让你无缝集成并处理各类应用场景下的空间数据，为企业提供可落地的空间智能支撑。

**CARTO分析工具箱精简版（Analytics Toolbox Lite）概览**

CARTO分析工具箱精简版由一组用户自定义函数（UDFs, User-Defined Functions）构成，用于扩展Snowflake的地理空间功能。这些函数按功能划分为不同模块。本套件包含一系列开源模块，支持多种空间索引及其他地理空间操作，例如：
- 变换类操作：如ST_BUFFER（用于从地理点生成指定半径的圆形区域），或ST_CONCAVEHULL（用于计算覆盖一组点的最小凹包区域）。
- 基于H3的增强函数（超越Snowflake原生能力）：如H3_KRING（用于计算同心H3环构成的区域）。
- 聚类类功能：如ST_CLUSTERKMEANS（用于基于点间距离计算点集群）。
- 处理类操作：ST_VORONOIPOLYGONS（用于从一组点生成泰森多边形）。
- 以及更多面向云原生地理空间分析的基础能力。
