Combine layers with different projection using a transformation

[Laurensvan_der_Burgt]

Hi all,

does the Flex API offer functionality to dynamically apply a geographic transformation in case a layer has a different projection than the Map object?

For example: in ArcGIS Desktop I would deal with this by defining the transformation as coordinate system option of the dataframe.

So far I have reprojected my data to match the basemap (web mercator), but this only works for my own data (not 3rd party services).

It would be possible to create a mapservice which applies this transformation to a 3rd party service,
however this is not desirable because of performance.

Regards,

The Flex API does not support client side reprojection. If you're using a dynamic layer or feature layer, the API will request that the server do the reprojection when it creates the map image or returns the feature set.
