[mapserver-users] Trouble with mode=tile

[Fawcett, David]

Dave, 

I am not sure if this is it, but in your WMS request, you are not
specifying a SRS.  You are advertising two SRS' in your WEB WMS
"wms_srs" metadata.  I wonder if MapServer is just defaulting to the
first SRS in your list in the absence of an explicit request?  

David.

Hi list, I'm using the latest ms4w on a windows XP box. When trying to 
use mapserver's tile mode in a Virtual Earth or Google Maps control, it
looks totally wrong (like the wrong projection is being used 
perhaps?). What is the right way to go about this?

Here's mapserver.exe -v:

C:\ms4w\Apache\cgi-bin>mapserv -v
MapServer version 5.2.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP 
OUTPUT=PDF
 OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE 
SUPPORTS=ICO
NV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT 
SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER 
SUPPORTS=FASTCGI SUP
PORTS=THREADS SUPPORTS=GEOS SUPPORTS=RGBA_PNG INPUT=JPEG INPUT=POSTGIS 
INPUT=OGR
 INPUT=GDAL INPUT=SHAPEFILE

Here's the relevant part of my web page with the map control:
        map=new VEMap('myMap');
        // ...
        var layerId = "myCustomTileLayer";
        var tileSource = 
"http://localhost/cgi-bin/mapserv.exe?map=/src/maps/mapdata/maps/dave1.m
ap&layers=world&mode=tile&tilemode=ve&tile=%4";
        var tileSourceSpec = new VETileSourceSpecification(layerId, 
tileSource);
        // ...

Here's the last line of my EPSG file (from c:\ms4w\proj\nad\epsg)
        # google/virtual earth spherical mercator
        <900913> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0

+x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs <>


And here's my map file:
