Hi, thanks for your reply. Results follow:
I can't remove the PROJECTION block, otherwise I get this error from
mapserver:
msTileSetProjectionst(): WMS server error. Cannot set new SRS on a map
that doesn't have any projection set. Please make sure your mapfile has
a PROJECTION defined at the top level.
QGis thinks this is the spatial information for my test shapefile, this
is 4326 (basically unprojected), right?
+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs
If I have the PROJECTION block in the mapfile, I can indeed see tiles of
some kind, but it looks like each tile overlaps in its spatial extent.
See attached for "wrong" results..I changed some of the colors so it
would be more obvious.

Dave,
- Remove the PROJECTION block from the MAP level (leave the one at the
LAYER level). Tile mode constructs its own output projection object,
it doesn't need map file configuration for the output projection, just
the inputs.
- Confirm that the shape file you are using *is* in fact epsg:4326
- Try manually accessing the service using tile=0 or tile=1, and see
what comes back
- Show some pictures of "wrong" in your next mail

Thanks for the suggestions, but I don't think that's quite it:
1 - removing "epsg:4326" from the wms_srs part of the mapfile didn't fix it
2 - adding "&SRS=EPSG:900913" to the Virtual Earth "tileSource" string
didn't fix it
Is there anything else I can try?

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.

Subject: [mapserver-users] Trouble with mode=tile
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 +nadgri...@null +no_defs <>
And here's my map file:
