[Geotools-gt2-users] getting layersbounds from DefaultMapContext
|

Hi,
We are trying to get the boundaries of the layers within a
DefaultMapContext
by using map.getLayerBounds(). It is throwing the following
error:
Aug 18, 2005 4:14:10 PM org.geotools.map.DefaultMapContext
getLayerBounds
SEVERE: Data source and map context coordinate system differ,
yet it was not
possible to get a projected bounds estimate...
org.opengis.referencing.operation.OperationNotFoundException:
Bursa wolf
parameters required.

Does this mean I have to change the projection of my
DefaultMapContext? I
tried to do this through map.setAreaOfInterest(areaOfInterest,
crs) but this
didn't seem to correct the problem.
Thanks,
Scott
