TXT FILE CREATED FROM ESTIMATES FILE (.txt) 
Interpolated estimates files ( ‘filename’.est) can be reformatted as ‘filename’.txt files 
which can be readily imported into other applications, including Arc/Info and 
Arc View. The .TXT file contains the values for each cell in the original Estimates 
file, from surface to bottom for each cell location. In addition, each line in the file is 
padded with -9 values. So the file is a rectangular matrix of data with all values 
having a value. The file is comma delimited, and all extraneous blanks have been 
removed. The precision of the reported parameter values are assigned by the values 
set in the ‘parameter.sys’ file. The .TXT file contents include: 
Line l>Coiumn Headings 
Line 2+>cell easting, cell northing, segment name, cell e-w dimension in meters, cell n-s dimension in 
meters, cell vertical depth in meters, bathymetry depth in meters, interpolated values from surface to 
bottom, additional depths padded with -9 down to !ayer_45, then bottom, minimum, maximum, mean, 
and sum values for non-missing cells in this water column.
