[fusion-users] Fusion + MapServer + TileCache

[Paul Deschamps]

Hi Tim.

I've setup a tilecache using the default "basic" layer as a test, our appdef
is as follows:

<MapSet xsi:type="MapSetType">
    <MapGroup id="mixed" xsi:type="MapType">
        <Map xsi:type="WMSLayerType">
            <Type>WMS</Type>
            <Extension>
                <ResourceId>http://192.168.2.105/cgi-bin/tilecache.cgi
</ResourceId>
                <Options>
                    <name>test tilecache WMS</name>
                    <isBaseLayer>true</isBaseLayer>
                    <singleTile>false</singleTile>
                </Options>
                <Parameters>
                    <layers>basic</layers>
                    <transparent>true</transparent>
                </Parameters>
            </Extension>
        </Map>
    </MapGroup>
</MapSet>

<MapWidget xsi:type="WidgetType">
    <Name>Map</Name>
    <Type>Map</Type>
    <StatusText>The map.</StatusText>
    <Extension xsi:type="CustomContentType">
        <MenuContainer>MapContextMenu</MenuContainer>
        <FractionalZoom>false</FractionalZoom>
    </Extension>
    <MapId>mixed</MapId>
</MapWidget>

Initially mike and I noticed that the tilecache requests were not using the
correct scale. Mike later found that the issue was that the map was using a
"fractional zoom" and once we added "<FractionalZoom>false</FractionalZoom>"
to the map widget it worked perfectly. Perhaps we should have a bug for this
and check to see if the map has <singleTile>false</singleTile> then
automatically set fractional zoom to false.

Now looking at your AppDef. I can see why you are looking at tilecache. I
bet thats expensive to have fusion load 11 map files. Is there not any way
you can have one map file with layer grouping? that would save you a ton of
bandwidth and would improve map draw speed having only 1 request instead of
11.

Remember though it is really only good to use tilecache on layers that do
not change. Any dynamic data means the you'll have to clear the cache at the
same interval that the data is updated.

Cheers

Paul.
