[mapserver-users] IIS and mapfiles and also GDAL

[Brent Fraser]

Chris,

   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.

   The way I access Mapnik tiles in mapserver is to create a layer in 
the map file:

LAYER
     DATA "frmt_wms_openstreetmap_MAPNIK.xml"
     NAME "Mapnik"
     PROJECTION
       "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"
     END
     STATUS ON
     TYPE RASTER
     PROCESSING "OVERSAMPLE_RATIO=1"
     PROCESSING "LOAD_FULL_RES_IMAGE=NO"
     UNITS METERS
END # LAYER

and frmt_wms_openstreetmap_MAPNIK.xml XML file of

<GDAL_WMS>
<Service name="TMS">
<ServerUrl>http://tile.openstreetmap.org/${z}/${x}/${y}.png</ServerUrl>
</Service>
<DataWindow>
<UpperLeftX>-20037508.34</UpperLeftX>
<UpperLeftY>20037508.34</UpperLeftY>
<LowerRightX>20037508.34</LowerRightX>
<LowerRightY>-20037508.34</LowerRightY>
<TileLevel>19</TileLevel>
<TileCountX>1</TileCountX>
<TileCountY>1</TileCountY>
<YOrigin>top</YOrigin>
</DataWindow>
<Projection>EPSG:900913</Projection>
<BlockSizeX>256</BlockSizeX>
<BlockSizeY>256</BlockSizeY>
<BandsCount>3</BandsCount>
<Cache />
</GDAL_WMS>
