3.1 Community and Capacity Building
The workshop series has provided an enhanced awareness of the issues
and problems of integrating data and information across spatial scales.
A cadre of scientists have had opportunity to apply the LOICZ typology
tools and database – and to contribute to the further development of
the methodology and approach by contribution of outcomes and identification
of additional data requirements. The discussions and interactions during
the workshops have led to further collaboration and utility of the tools
and their applications to other local and regional issues beyond the
goals of the LOICZ-UNEP project. For example, New Zealand scientists
are developing an estuarine classification system for environmental
management purposes. This requires a finer scale of resolution than
the global half-degree scale application of LOICZ. The Loiczview tool
is being used with a separate and detailed database in these developments.
Similarly, the tool and databases are being applied to questions in
other parts of the world often augmented with local regional data relevant
to the research issues.
Most participants in the workshops had attended earlier and companion
workshops addressing biogeochemical budget development in different
continental regions of the world. The network of scientists from the
biogeochemical budgets has been active and sustained in the further
development of biogeochemical budgets for additional sites – these have
been incorporated in the database. This work continues and the approach
is used in formal teaching and training courses in various regions.
The typology workshops have involved additional scientists, particularly
those with experience in geoinformatics, and the resultant interactions
have led to a number of products exemplified in the attached CD-ROM.
Importantly, the network of scientists continues to collaborate on scaling
and typological research beyond the workshops adding to the products
for the project and applying the approach to allied problems. A final
global integration workshop for the project is scheduled for late 2001
and is expected to add further impetus to the network and the wider
issue of scaling and coastal classification.
3.2. Coastal characterization
3.2.1. General
Major progress was made over the course of
the three workshops in terms of both coastal characterization itself
(typology) and the conceptual and operational tools available for the
task. The strategy of having workshop participants work on and report
typology experiments of their own devising produced an eclectic mixture
of products and experience. These are listed and briefly described
or discussed in section 3.2.4 below, and in more detail in Appendices
IC, IIC, and IIIC. Most of the contributions were prepared in electronic,
browser-viewable form; these are available for review and examination
on the CD-ROM accompanying this report, and on the project web site.
Sections 3.2.2 and 3.2.3 below briefly summarize
the developments in the Web-LoiczView tool and in the typology (now
combined with budgets) database. This is done for two purposes: to
document the power of the workshop process in identifying and shaping
the necessary developments; and, to provide a context in which to view
the participant contributions from the three workshops. Major changes
in both the presentational and analytical tools available over the course
of the project, as well as in the variables available for analysis,
mean that there are substantial differences in form and content between
otherwise similar experiments in the first (Australia-Asia) and the
final (Europe-Africa) workshops. It is a tribute to both the underlying
robustness of the approach and the dedication and quality of the workshop
participants that this developing framework does not lessen the conceptual
and practical significance of the work done in the earlier stages of
the development.
3.2.2
Web-LoiczView developments
The major capabilities added to the WLV application
over the course of the project were the eigenvector analysis (principal
components) package, and the cross-clustering operation (see the CD-ROM
or web site tutorial pages for descriptions of these features). Other
developments, however, had comparably significant effects on the ease
of use and the products. These include file management options such
as the ability to rename and combine files, enhancements to the tolerance
of the application for the formats of uploaded files, and substantial
expansion of the labels and information messages provided to the user.
Equally important were the major additions
in terms of information available for easy use, capture and download.
The “point identification” function in the cluster visualization was
added, as were additional summary statistics in the “information” outputs
of the overlay and dual visualization operations. The extent of data
available for download and the ease of doing so were increased, and
the ability to save products in conveniently usable format (html, pdf,
text) was expanded.
3.2.3
Database developments
Over the course of the project the actual contents
of the database were greatly expanded, and ‘debugging’ and refinement
improved the utility of the existing contents. A major effort was devoted
to incorporating the river basin variables provided by the University
of New Hampshire-BAHC groups; this included not only adapting the model
flow and cell structure to the LOICZ system, but also populating the
basins with additional variables and working through the ways of presenting
and using cumulative basin data projected onto one or a few coastal
cells. Other substantial additions included addition of ocean color
(chlorophyll) data, and greatly expanded hydroclimatology data.
User-support tools in the ‘front end’ of the
database were developed to provide major improvements in the users ability
to review, select, and modify the available data. Additional cell categories
were added to provide truly global coverage, and various options for
the arrangement of the variable selection pages were provided. The
major development efforts provided extensive new capabilities for dealing
with the data set assembled. The user can now view summary statistics
and a histogram, exclude null values, filter, selectively modify, or
transform any of the variables in a data set, and can create a correlation
matrix for the entire data set.. These added tools greatly facilitate
data selection for clustering.
