This CD contains final magnetic and digital 
elevation model data for the Zeehan airborne 
geophysical survey flown by Fugro Airborne

survey areas for this job - Renison East, Heazlewood
and Zeehan.  ERMapper grids and ASEG-GDF 
format ASCII located data are supplied.

The ERMapper grids are:
finmag.ers        final magnetic data
finmag_rtp.ers    final magnetic data (reduced to the pole)
finmag_1vd.ers    final magnetic data (first vertical derivative)
finmag_2vd.ers    final magnetic data (second vertical derivative)
finmag_ansig.ers  final magnetic data (analytic signal)
findem.ers        final digital elevation model data

The ASEG-GDF format ASCII located data are:
mag.dat     (.des .dfn) magnetic data
dem.dat     (.des .dfn) DEM data
The ASCII located data is contained in the 
.dat files, while useful survey information 
and ASCII format information is found in the
.des and .dfn files.

Also contained on this CD is Trial Harbour 
magnetic and DEM data flown by UTS in 1998.  
ASCII located data (.ldt) and headers (.txt)
are supplied along with ERMapper grids.
Also supplied is a merge of these 1998 magnetic 
and DEM grids with the new Zeehan area grids.

This CD also contains maps for each of the three new 
survey areas as well as maps of the merged area:
