Key concepts

There are a few concepts that are repeated throughout the different Analytics Toolbox modules and functions, and that are unique to geospatial analytics. In this section of our documentation you will find some articles to introduce you to some of those key concepts.

• Spatial Indexes: spatial indexes are systems that provide a relationship between geospatial data and a hierarchical grid system, represented by geospatial indexes. There are huge performance and scalability benefits of aggregating data using spatial indexes. The most common spatial indexes libraries are Quadbin and H3, which CARTO supports with different modules in the Analytics Toolbox. Learn more about spatial indexes in the following subsection.
