Getting blank tiles in google maps
================================================

Hi all, I am new to MapServer.

I have downloaded and setup MS4W and was able to overlay the example Bath
and other map data on google maps.

I then created my own .map file using QGIS and supplied my data but the
served tiles are completely blank(transparant or white when I select RGB).

My data set is .GML and I also tried converting it to .SHP format. I have
checked that my setup is ok by doing is on two different computers.

When I use shp2img.exe then it renders the layers properly.
c:\> shp2img.exe -m hampshire.map -o hampshire.png -s 2048 2048

I am using this URL scheme:
http://localhost:8088/cgi-bin/mapserv.exe?map=C:/ms4w/apps/gmap/htdocs/hampshire.map
&layers=HampshireAreas&mode=tile&tilemode=gmap&tile=[x]+[y]+[z]

I have attached all the relevant files. (2 sets, one is .SHP and the other
is .GML, both cases I get transparent empty tiles)

Can anyone please help me identify the reason why the generated tiles are
transparent and how I can fix it.

(7MB total, 1MB pieces, sorry if this is large, I am new to mailing lists
too, please use 7Z to unzip)
SHP: Hampshire.map Hampshire.7z.001 Hampshire.7z.002 Hampshire.7z.003
Hampshire.7z.004 Hampshire.7z.005 Hampshire.7z.006 
GML: Hampshire-gml.map Hampshire-gml.7z 

Alternate download (zip format, 14mb) http://www.megaupload.com/?d=DAD6SR5P 

Thanks you very much.
