Q: 

What is a SPATIAL INDEX and when should I use it?

Like most of the average PHP web developers I use MySql as a RDBMS. MySql (as other RDBMS also) offers SPATIAL INDEZ features, but I'm don't get it very well. I goole for it but I don't found clear real world examples to clearify my bad knowledge about it.

Could someone explain me a little bit what is a SPATIAL INDEX and when should I use it?

Best, Demian

+1  A: 

You can use a spatial index for indexing geo-objects - shapes. The spatial index makes it possible to efficiently search for objects that overlap in space
