- 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.
- An interesting PDF article from ERDAS on Visualizing The Sea Floor .

| 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.

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 address various aspects of
Complex Systems and Artificial Life.
-
Complex Adaptive
