| In addition to specialized links on my other
pages, I'm providing links on various subjects
that directly or indirectly pertain to computer
visualization of the marine environment. The
categories by which I classify these links will
change as I receive submittals
from you. |
| Submarine
Topography |
 | Dr. Dawn Wright of
Oregon State University has a comprehensive web
site dedicated to marine/coastal GIS and
the processing, production, visualization,
and interpretation of seafloor maps.
| The Ocean
Mapping Group at the University of New
Brunswick focuses on developing new and
innovative techniques and tools for the
management, processing, visualization, and
interpretation of ocean mapping data. |

Visualization Tools |
| DLGV32
is a public domain 2D map viewer
produced by the USGS. It can handle many
file formats and color schemes. The full
source code for the viewer is free from the
US government. A great viewer for testing
GTOPO30 bathymetry data.
| MICRODEM
is a microcomputer mapping program from
the Oceanography Department at the U.S.
Naval Academy. It is one of the few viewers
that gracefully handles bathymetric data.
However, it does not handle unknown vales
well.
| TRU_FLITE
is a commercial map viewer that has a
demo version available. It handles GTOPO30
files along with other formats.
| 3DEM
is a shareware three dimensional viewer
that handles GTOPO30 data and other formats.
| Terrain
Bits provides a list of other terrain
viewers and terrain generators.
| Shale
Software presents a nice shapefile
viewer. |

| Bathymetry
Data Sources |
| The National
Geophysical Data Center (GEODAS), produces digital
bathymetry databases of ship-based
soundings. These data have recently been
released as CD-ROM sets with PC-compatible
search and retrieval software.
| Scripps Institute Of
Oceanography has developed new 2 minute worldwide
seafloor topography bathymetry data
using satellite imagery and ship-based depth
soundings. The huge (132 meg) dataset can be
downloaded or a CD is about to be produced
for distribution.
| The Digital Bathymetric
Database - Variable (DBDB-V) from the Naval
Oceanographic Office (NAVOCEANO) is a
digital bathymetric database that provides
ocean depths at various gridded resolutions.
This online
database may be queried by specifying
point location, an arc of a great circle, or
a bounding rectangle. Information and
specifications about the database can be
found here
. This dataset is a good starting point
because the data are spline interpolated to
the resolution requested by the user.
However, it lacks accuracy (particularly
below 29 degrees North) and requires
updating from measured sources such as the
GEODAS data set.

| GeoData
Sources |
| The GTOPO30
data format page. GTOPO30 is a 30 arc
second binary DEM format that is a good
model for submarine topography data.
| The University of Iowa
provides a very large list of geodata
information sources . |
|
|
| Geospatial
Interpolation |
| Unlike available terrain
elevation data, available bathymetry data is
sparse and/or not provided at a 30 arc-second or
better resolution. As a result, geospatial
interpolation methods are necessary to estimate
the unknown values. It is also possible to use
"fractal forgeries" to fill in missing
bathymetry data. |
| Kriging
Interpolation notes and source code by
Chao-yi Lang at Cornell. If you are a C
programmer, this site will prevent you from
"re-inventing the wheel". Chao
bases his code on a great book -- An
Introduction To Applied Geostatistics by
Isaaks & Srivastava. Oxford University
Press, 1989 ISBN 0-19-505013-4.
| There are a number of
techniques for statistically interpolating
geospatial data that are described in
lecture notes and outlines from various
institutions.
| Fractal methods for
developing landscapes have been become
famous.

|
| Multidimensional
Database Development |
| The NCSA
HDF data file format home page. HDF is
potentially a great format for
multidimensional marine databases. Any
comments or suggestions???
| Dr. Dawn Wright, ESRI, and a team of
collaborators are developing specifications
for a Marine Data Model. Progress
of this important work can be monitored
at a regularly updated web site. While this
current effort is oriented toward ESRI
ArcGIS standards, the work is expected to
expand to include other formats. |

| The mission of the Digital
Biology Project is to promote and assist
in the engineering of complete,
biologically-inspired, synthetic ecosystems
and organisms. This involves the creation
and deployment of digital tools and
environments for simulation, research, and
learning about living systems both natural
and artificial. These tools could range from
simple genetic algorithms all the way up to
full multi-user virtual environments.
| CALResCo
has a marvelous site with a large number
of links to Web sites and papers that
