Top level directory:

file is intended to be the starting point for accessing this CD-ROM. It
is written in the Hypertext Markup Language utilized by the World Wide

may browse the CD-ROM's contents as they would pages from the WWW.
Directories:
Directory data
- What follows is a brief description of the data contained in the underlying
directories.
- 2004 -
contains all the raw and processed Continuous Resistivity Profile (CRP)
data from the Neuse River estuary collected in 2004. The subdirectories
indicate the type of data (e.g. processed, raw, RES2DINV). They are
then further broken down by day of survey. Below is an example directory
structure, only showing survey day April 19. In addition to April 19,
folders for April 20 through April 23 are available.
- proc_resis
- results of CRP data processed with Advanced Geosciences, Inc.
(AGI) EarthImager 2D software.
- apr19
- def_wres
- contains the minimum essential files output from
EarthImager, using a default water resistivity value in
the DEP file. These files include the linearized STG file,
the DEP file (edited where appropriate to remove spurious
bathymetric values), the XYZ file (where X is distance along
line, Y is depth, and Z is resistivity value), the parameters
initialization file, and the resultant JPEG CRP profile
with bathymetry shown as a white line.
- wres
- contains the minimum essential files output from EarthImager,
using a measured water resistivity value in the DEP file.
These files include the linearized STG file, the DEP file
(edited where appropriate to remove spurious bathymetric
values), the XYZ file, the parameters initialization file,
and the resultant JPEG CRP profile with bathymetry shown
as a white line.
- matlabimages
- JPEG images plotting the XYZ data with the superimposed
DEP bathymetry profile shown as a black line. All Matlab
images use a common color scale, with similar vertical and
horizontal scales (software limited). There is an image
for the data processed with the default water resistivity
as well as the data processed with a measured water resistivity.
- raw_resis
- apr19
- contains the raw STG and GPS files. In rare cases, one
or both of the files needed to be edited to remove spurious data
values that prevented processing. In those cases, the modified files
are available.
- res2dinv_format
- apr19
- contains the RES2DINV format DAT file. This file is
the result of running a VisualBasic6 program that reads the linearized
STG file and the DEP file and reformats them to the RES2DINV format.
The DEP file used has a measured water resistivity value.
- 2005 -
contains all the raw and processed CRP data from the Neuse River estuary
collected in 2005. The subdirectories indicate the type of data (processed,
raw, RES2DINV). Those are then further broken down by day of survey.
Below is an example directory structure, only showing survey day May
3. In addition to May 3, folders for May 4 and May 5 are available.
- proc_resis
- may3
- def_wres
- contains the minimum essential files output from
EarthImager, using a default water resistivity value in
the DEP file. These files include the linearized STG file,
the DEP file (edited where appropriate to remove spurious
bathymetric values), the XYZ file, the parameters initialization
file, and the resultant JPEG CRP profile with bathymetry
shown as a white line.
- wres
- contains the minimum essential files output from
EarthImager, using a measured water resistivity value in
the DEP file. These files include the linearized STG file,
the DEP file (edited where appropriate to remove spurious
bathymetric values), the XYZ file, the parameters initialization
file, and the resultant JPEG CRP profile with bathymetry
shown as a white line.
- matlabimages
- JPEG images plotting the XYZ data with the superimposed
DEP bathymetry profile shown as a black line. All Matlab
images use a common color scale, with similar vertical and
horizontal scales (software limited). There is an image
for the data processed with the default water resistivity
as well as the data processed with a measured water resistivity.
- raw_resis
- may3
- contains the raw STG and GPS files. In rare cases,
one or both of the files needed to be edited to remove spurious
data values that prevented processing. In those cases, the modified
files are available.
- res2dinv_format
- may3
- contains the RES2DINV format DAT file. This file
is the result of running a VisualBasic6 program that reads the
linearized STG file and the DEP file and reformats them to the
RES2DINV format. The DEP file used has a measured water resistivity
value.
- basemap
- contains files needed as a backdrop for the GIS. This includes state
outlines, the estuary bathymetry, and the NOAA medium resolution coastline.
- navigation
- contains shapefiles of the CRP tracklines, as well as point
shapefiles with a point at a specified distance along each trackline.
This is to help facilitate correlation between the CRP profile images
and the geographic location of the profile.
Directory htmldocs:
contains the HTML pages accessed within this report. This directory contains
the following subdirectories:
- 2004images_sm
- contains JPEG images of the 2004 CRP profiles. This includes downsampled
versions of the images generated by EarthImager and Matlab, as well
as the full-resolution Matlab-generated images utilized in the HTML
documents. All the full-resolution images are available from the appropriate
location under the data directory. The subdirectory "thumbs"
contains thumbnails of all the images.
- 2005images_sm
- contains JPEG images of the 2005 CRP profiles. This includes downsampled
versions of the images generated by EarthImager and Matlab, as well
as the full-resolution Matlab-generated images utilized in the HTML
documents. All the full-resolution images are available from the appropriate
location under the data directory. The subdirectory "thumbs"
contains thumbnails of all the images.
- icons
- contains miscellaneous images and icons used in the creation of the
HTML pages.
