Help with basemap/map server please

[McCainMcMurray]

I have just started working with the ArcGIS Viewer for Flex and would greatly appreciate some help with an issue I am having. I am not sure of the terminology, but here goes. I found a basemap/map server for New Zealand topo maps at this address:

http://services.arcgisonline.co.nz/ArcGIS/rest/services/LINZ/geotiffs/MapServer

I added this service to my main config file using the following code:

<basemaps>
<layer label="Topo" type="tiled" visible="true" url="http://server.arcgisonline.com/ArcGIS/rest/services/USA_Topo_Maps/MapServer"/>
<layer label="NZ Topo" type="tiled" visible="false" url="http://services.arcgisonline.co.nz/ArcGIS/rest/services/LINZ/geotiffs/MapServer"/>
<layer label="Aerial" type="tiled" visible="false" url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"/>
<layer label="Streets" type="tiled" visible="false" url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>
</basemaps>

When I select the NZ Topo basemap from my map switcher, the map is entirely gray. I would really appreciate any help fixing this issue.

Thanks

The tiles for the NZ map service has been created in a different projection.  You can see this at http://services.arcgisonline.co.nz/ArcGIS/rest/services/LINZ/geotiffs/MapServer where it says "Spatial Reference: 2193".

The flex viewer does not re-project cached services.

You have two options, the best one is to just use services in that projection, for example:

<map wraparound180="true" top="40">
    <basemaps>
        <layer label="NZ Topo" type="tiled" visible="true" url="http://services.arcgisonline.co.nz/ArcGIS/rest/services/LINZ/geotiffs/MapServer"/>
    </basemaps>

The other solution is to request a dynamicly created map from the LINZ service. This will not look as good, nor perform as well:

<map wraparound180="true" top="40">
    <basemaps>
        <layer label="Streets" type="tiled" visible="true"
               url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>
        <layer label="NZ Topo" type="dynamic" visible="false" 
                url="http://services.arcgisonline.co.nz/ArcGIS/rest/services/LINZ/geotiffs/MapServer"/>
        <layer label="Aerial"  type="tiled" visible="false"
               url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"/>
        <layer label="Topo"    type="tiled" visible="false"
               url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>
    </basemaps>

(make sure that the NZ service is not listed first, in which case the map will use the LINZ projection and the tiled from ArcGIS Online services will not work)

Thank you very much. Your solution worked perfectly.
