Using With MapServer

From OpenAerialMap

As of GDAL 1.5, there is support for requesting remote tiles from a WMS-C cache in GDAL.

To do this, simply drop the following into a file:

<GDAL_WMS>
   <Service name="WMS">
       <Version>1</Version>
       <ServerUrl>http://tile.openaerialmap.org/tiles/</ServerUrl>
       <Layers>openaerialmap</Layers>
   </Service>
   <DataWindow>
       <UpperLeftX>-180.0</UpperLeftX>
       <UpperLeftY>90.0</UpperLeftY>
       <LowerRightX>180.0</LowerRightX>
       <LowerRightY>-90.0</LowerRightY>
       <SizeX>1073741824</SizeX>
       <SizeY>536870912</SizeY>
       <TileLevel>21</TileLevel>
   </DataWindow>
   <Projection>EPSG:4326</Projection>
   <OverviewCount>21</OverviewCount>
   <BlockSizeX>256</BlockSizeX>
   <BlockSizeY>256</BlockSizeY>
   <BandsCount>3</BandsCount>
</GDAL_WMS>

Then use it in your mapfile like so:

   layer
     name  "world"
     type raster
     status on
     data "/my/path/to/oam_cache.xml"
     projection "init=epsg:4326" end
     offsite 0 0 0
   END

Before GDAL 1.5, you can instead use a remote WMS service to load the data: just use

 http://openaerialmap.org/wms/

with a layer of "world".
