## REPORT
# Spatial Indexes 101
## Everything you need to know about Spatial Indexes! Including what they are, why you should be using them and practical guides to get you started…
[](https://go.carto.com/report-spatial-indexes-101#form)
Spatial data is BIG. Sometimes, it’s too big - too big to render, analyze and interpret. One way of dealing with this challenge is the use of a support geography - a simplified representation of your data that is more manageable.
Enter Spatial Indexes.
Spatial Indexes are multi-resolution, hierarchical grids that are “geolocated” by a short reference string, rather than a complex geometry. Smaller to store and faster to process; they out-compete conventional geometries for complex data analysis and visualization.
*But where to start?* Spatial Indexes 101 is your ultimate guide to taking your analysis to the next level. In this ebook, you’ll discover:
- What the different types of Spatial Indexes are, and how to choose the right index type and resolution for your work.
- How to get started - loading indexes and understanding their properties.
- Practical guides and exercises for running analysis and gaining insights from your data.
And much more!
