Hi Folks,

This post contains no new information; it’s just a rollup of links to spatial indexing posts I’ve made.  If you want to know more about spatial indexing, these are the ones to read.

In order:

1. Why a Spatial Index?
2. A Simple Spatial Indexing Scheme
3. Faster Primary Filtering
4. Picking up on Indexing: Moving Beyond the Simple Grid
5. Basic Multi-Level Grids
6. More on the Multi-Level Grid
7. Is my spatial index being used?

Hmm… it looks like I never got around to the specific of the geography index.  It’s in the queue now.

Cheers,
-Isaac
