hey Group:

I have several NEDs that I downloaded in 1-degree blocks that I need to =
give to a co-worker to utilize in Micro station 8 with Geopack. I am not =
sure if he can import directly or not. =20

Can anyone suggest what I may have to do with these NEDs for him to use =
them. I am using ArcGIS 8.3 but only the ArcView functionality.
