If you are referring to tiles to be layered over existing Google tiles,
see Ducky Sherwood's census mashup site:
http://maps.webfoot.com/
She did that as a project for one of her courses:
http://www.cs.ubc.ca/~tmm/courses/infovis/projects.html#ducky
Specifically, she writes:
"I used the gd library[3] to draw the polygons (as given in the
shapefiles), filled with a color chosen based on the population (as
given population datafiles) divided by the area (as given in the shape
file). I wrote files out as PNG images."
I was trying to figure out how to get the output from shp2img to create
tile layers, but now am looking at using gd as well.

Hi guys,
I don't know whether this is a stupid question or what but I really
need some advice, opinions, or whatever since I am stuck with this
problem for so many days already.
Anyway what I am trying to do is to create map images that I can use
to implement my application like Google Maps. I know that within
Mapserver there is ka-map but as stupid as I am, I would like to
create my own. The details of ka-map and the lack of documentation
making ka-map a bit confusing to me.
I need to make tiles for all map images that I generated from .map
file. The problem I have is that I don't know how to generate images
for zooming in and out the map. I've tried changing and using EXTEND
variable but EXTEND only displayed a certain area of the map and not
the entire data. So basically if the user drag the map they will only
see data on that extend and not the entire map. How can I solve this
problem? I tried using and changing the SCALE value but nothing
changed? I tried to changed the SIZE also nothing changed except the
pixel size of the map.
So anybody out there that can help me with the best approach? I need
to generate the image and then cut it to tiles. I think I have a
solution on how to cut the image but producing the image is now the
problem. I hope you guys get the picture.
Thanks.
Ed.
