hi everybody,

i would really appreciate if anyone could help with the following problem:

i have app. 100 rasterdataset which do not have any projection defined (anyway i know they are xxxx because of the coordinates...) There´s a tool "define projection" in the arctoolbox. is there a possiblity to define projection in one step for all of the rasterdatasets in my workspace (something like batch define projection) in ArcCatalog 10???
