Overlapping NED Data?

I have some 1/3" NED data in zipped ArcGRID format, some of the files overlap coverage, need some advice, I'm creating contours:
  1. Can I just let these files overlap?
  2. or can I crop and export, if so what file format? Zipped ArcGRID is not an option.

Don't have any root knowledge of elevation data.

Thanks

    I would just let the files overlap. Global Mapper will use whatever layer is on top at each location when generating the contours.

    Let me know if I can be of further assistance.

    Thanks,

    I was hoping overlapping was okay.

    Thanks
