Matt, Bertram, here is a report on SEEK activities as requested.
Suggestions welcome as always. Cheers
Summary of the SEEK project activities led by David Stockwell at
(SDSC)
1-Sep-2002 to May-2003.
Meetings
David Stockwell participated in major meetings held at New Mexico (20-24
Feb 2003) and San Diego (10-16 May 2003) and in ad-hoc weekly meetings
held at San Diego.
Personnell
Two programmers were hired during the period. The primary role has been
to develop and modify parts of a prototype species mapping application
called WhyWhere (WW) to provide a more mature application and serve as
the basis for exploring issues related to provision of analysis services
via the EcoGrid. Work performed was:
1. Valentina Kouznetsova - 5months at 25% time now finished.
Valentina modified image processing libraries to eliminate
unnecessary image format conversions, eliminating a Perl library
and converting the central routines from Perl into C code. She
has also extracted the central clustering algorithm from the
libraries into stand-alone C code, allowing most of the
computationally intensive prediction routines in WhyWhere to be
implemented in C.
2. Yang Yu - Graduate Research Assistant from March to present at
25-50% time. Yang initially converted a number of large
hydrological datasets into pgm format for incorporation into the
WW modeling system. Yang has modified image processing libraries
for preparation of environmental data layers for modeling in the
WW system, greatly increasing the speed. He has also developed
some prototype applications to evaluate the speed of a possible
visualization tool for large environmental data sets.
Future Work.
The main area we will pursue for SEEK is the exploration, development
and incorporation of Geographic Information System (GIS) based data,
services and protocols into the EcoGrid via the implementation of a
number of applications as services using the OGC standard. This work
will provide a basis for future enhancements using rnowledge
representation approaches from SEEK groups KR and SMS as they become
available. The goals of our work in the next period will be:
1. To develop a generic Web Mapping Service (WMS) compliant with
appropriate OpenGIS Consortium (OGC) specifications.
2. Consolidate the work done on WW and incorporate the WMS developed
above into WW operation.
3. Develop a visualization service for the large environmental data
sets used in WW.
4. Develop a WSDL definition of the OGC services for incorporation of
the WMS into METACAT or SRB
