[postgis-users] Help finding information on creating a "Heat Map"

[Woody Woodring]

I am looking for information/advice on creating a "surface theme layer" or
"Heat map layer" on my map.  

I currently have my data stored as points in Postgres/Postgis database and
need to output as continuous color gradation layer on Google maps.  My
current uninformed thinking is as follows:

1) Convert the point info into some other spatial representation in the
database
2) Use GeoServer to create a WMS layer using the new representation. 

Any advice would be greatly appreciated.

Woody
