If you have a current version of Mapserver (v5,v6?), then should
be GDAL compiled in. The GDAL library needs to find projection
definition files so I usually include the following in all my map
files:<br>
<br>
CONFIG "PROJ_LIB" "\ms4w\proj\nad"<br>
CONFIG "GDAL_DATA" "\ms4w\gdaldata"<br>
<br>
Another potential problem you may be having is with EPSG:900913.
It is not included in GDAL/PROJ's epsg file so I add the following
to \ms4w\proj\nad\epsg:<br>
<br>
<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

Thanks for the quick answers, the new rewriting rules (with
reverse proxy) have worked well with Tomcat on port 8080 - no more
isapi dlls! What you listed for Mapnik is essentially like mine,
what I am not sure is what other GDAL configuration is needed on
the box - just an environment variable or some other setting in
the mapfile...?<br>
<br>
Thanks<br>

I've used the Iconic Rewriter with older versions of IIS
(the native rewriting capability in IIS7 looks
interesting). You may be able to use an environment
variable to set the default map file, but this may not be
very useful if you have multiple map files. There are a few
other options for hiding the mapfile (proxy script,
redirect, form post instead of get, etc), put I think the
rewrite method is the most effective (the client never gets
the map file path), with almost no performance hit.<br>
<br>
The way I access Mapnik tiles in mapserver is to create a
layer in the map file:<br>
<br>
LAYER<br>
DATA "frmt_wms_openstreetmap_MAPNIK.xml"<br>
NAME "Mapnik"<br>
PROJECTION<br>
"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"<br>
END<br>
STATUS ON<br>
TYPE RASTER<br>
PROCESSING "OVERSAMPLE_RATIO=1"<br>
PROCESSING "LOAD_FULL_RES_IMAGE=NO"<br>
UNITS METERS<br>
END # LAYER<br>
<br>
and frmt_wms_openstreetmap_MAPNIK.xml XML file of <br>
<div class="im"> <br>

<div class="h5">Hi<br>
<br>
I just wanted to check if the only way to parse a
mapfile in an IIS environment to use an absolute path
to the mapfiles e.g. <a moz-do-not-send="true"
href="http://myserver/cgi-bin/mapserv.exe?map=C"
target="_blank">http://myserver/cgi-bin/mapserv.exe?map=C</a>:\Inetpub\wwwroot\workshop\itasca.map.
I wonder if anyone has had success with rewrite rules
(IIS7)?<br>
<br>
Also how is GDAL triggered when calling the mapfile
(in IIS). The scenario is I am trying to use an xml
in the mapfile layer which then calls <a
moz-do-not-send="true"
href="http://tile.openstreetmap.org/"
target="_blank">http://tile.openstreetmap.org/</a><br>
<br>
The XML is<br>
<br>
<GDAL_WMS><br>
<Service name="TMS"><br>
<ServerUrl><a moz-do-not-send="true"
href="http://tile.openstreetmap.org/$%7Bz%7D/$%7Bx%7D/$%7By%7D.png"
target="_blank">http://tile.openstreetmap.org/${z}/${x}/${y}.png</a></ServerUrl><br>
</Service><br>

<LowerRightY>-20037508.34</LowerRightY><br>
<TileLevel>19</TileLevel><br>
<TileCountX>1</TileCountX><br>
<TileCountY>1</TileCountY><br>

<BlockSizeX>256</BlockSizeX><br>
<BlockSizeY>256</BlockSizeY><br>
<BandsCount>3</BandsCount><br>
<Cache/><br>
</GDAL_WMS><br>
<br>
Am I remotely doing this the right way? I am used to
calling local data from the mapfile and tiled services
is a bit of a new beast, so I thought I would give it
a go!<br>
<br>
Many thanks in advance<br>
<br>
