Lake Champlain Detail Project 6012

A lot of basic information was missing from the data set.  Channels had to be created for
geology, diurnal, fid, and resmag.  Resmag was calculated using a DIGRF.  No regional
field had been removed from the original data.  This detail area was fully incorporated in
the larger data set but was separated out for presentation.  It still remains in the
larger set.
