Hi,
Just want to share my methode.
What I did with my hybridmap is just drawing ocean layer (shape file)
after draw hillshading. So my XML file as follow:
<Map srs="+proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=6378137 +b=6378137
+units=m +no_defs">
<Layer name="shade" status="on">
<StyleName>shade</StyleName>
<Datasource>
<Parameter name="type">gdal</Parameter>
<Parameter
name="file">/map/srtm/hillshade/indonesia_shade.tif</Parameter>
<Parameter name="format">tiff</Parameter>
</Datasource>
</Layer>
<Style name="shade">
<Rule>
<RasterSymbolizer>
<CssParameter name="opacity">0.7</CssParameter>
<CssParameter name="scaling">bilinear</CssParameter>
<CssParameter name="mode">screen</CssParameter>
</RasterSymbolizer>
</Rule>
<Style name="polyg_ocean">
<Rule>
<PolygonSymbolizer>
<CssParameter name="fill">#97AFD5</CssParameter>
<CssParameter name="fill-opacity">1</CssParameter>
<CssParameter name="gamma">0.7</CssParameter>
</PolygonSymbolizer>
</Rule>
</Style>
<Layer name="polyg_ocean" srs="+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 +over">
<StyleName>polyg_ocean</StyleName>
<Datasource>
<Parameter name="type">shape</Parameter>
<Parameter
name="file">/map/srtm/hillshade/Indonesia_Ocean.shp</Parameter>
</Datasource>
</Layer>
</Map>
