GWS and OGC Network
• OGC Network has been updated based upon on the 13
June Telecon discussions:
– http://www.ogcnetwork.net/GEOSSdemos
• Note in particular the beginnings of a page for base WMS
servers useful for most all demos.
• If you anticipate wanting to edit the OGC Network Pages
for GEOSS:
– http://www.ogcnetwork.net/user/register

GEOSS Demos Lessons Learned
• Application-specific demos are a great way to engage with user communities that would
not necessarily look to OGC standards.
• Emphasize message about using distributed components with open standards vs.
standalone application
• Tremendous enthusiasm and commitment of agencies and research groups to
collaborate
• Demo provides a fast-track to skills development and knowledge transfer.
• Live demo is compelling but dependent upon communications networks that may not be
reliable at workshops
• Live demo should be accompanied by a pre-recorded demo
• Presentation of the demo works best with two projectors: one for the client application,
the other for a powerpoint presentation explanation
• Start early to get satellite data
• Desirable to involve participants from the local region
• Keep it simple, focus on the magic of interoperability
• GEOSS Demos are persistent using OGC Network

GeoWeb Portal Candidate Presentation
• Committed to Standards
• Our Vision of the GeoWeb Portal
• The Compusult WES GeoWeb Portal
A suite of applications providing a real-time, web-based, geospatially enabled portal to
provide centralized interoperability, discovery, collaboration, sharing, access and
management over highly disparate information.
• How WES is Currently Used
– Selected Organizations using Web Enterprise Suite
• WES GeoWeb Portal Architecture Overview
• WES supports the following standards:
• WES Platform Independence
– WES X software components have been designed and implemented to operate across multiple
platforms. Operating Systems currently supported:
• WES: The Total Geospatial Portal Solution
• GeoWeb Portlets included in WES
– Discovery, Discovery agents, Viewer, Publisher, Administration, Colaboration, Other
• Benefits of a WES GeoWeb Portal

Additional info for GeoNorth
GEOSS Workshop at GeoNorth
• Data sources for Demos
– Use both Polar and Cylindrical projections.
• (Comment on telecon that we may not want to use EPSG:32661 - polar
stereographic projection centered at the north pole - to be clarified)
– (Need caribou data on WMS - maybe with CARMA group?)
– NSIDC Atlas of the Cryosphere - John Maurer ([email protected])

– WMS from Geoconnections
• http://geodiscover.cgdi.ca/gdp/search?action=searchForm&entryType=service
– Atlas of Canada - WMS with base layers (road, boundaries,
hydrography, populated places, etc.) for its 7.5 Million framework
data set.

WMS for Canadian topographic data
• The link to WMS for Canadian topographic data in the
North is
• http://wms.ctis.nrcan.gc.ca/wms/en/index.html
• You will have to register to get the address of the service, it
is free.
• The available digital topographic data are vector layers,
DEM layer,ortho Landsat 7 layer, raster maps, etc.
• I hope these data may be of help in supporting the
scenarios for the GEOSS workshop in Yellowknife.

• Here are some scenarios suggested by one of the science people. 1. Movement of
caribou in spring and timing of greeness 2. Calving area use and greeness 3. CAR
Movement and timing and location of snow or ice on lakes 4. CAR Movement and
location of winter road, mines 5. Paterns in wintering areas and fire zones (show red on
sat images) etc

GBIF network
• Hi George,
• The number of records in the GBIF network for the Polar
scenario bounding box for the period April 1996 to
December 2006 is ca. 22850. From a quick exploration, the
main groups are birds (19538 records), mammals (2156)
and arachnids (741). If anyone has more specific questions
about particular groups, please get back to me.
• Best regards,
• Éamonn
• Just received main that Stefano Nativi’s demo re:
biodiversity from Barcelona maight also be available for
GeoNorth.

GBIF network
• The following table provides a breakdown of the georeferenced species
occurrence records per country served via the GBIF network .
• Amongst African countries, you will see that South Africa is way ahead
with 2098697 records, followed by Madagascar, Tanzania, Congo,
Kenya, Cameroon, Ethiopia, Uganda, Mozambique, each with more
than 10,000 records. Depending on which African countries/areas you
plan to use for the scenarios, I can do a more detailed check within a
country to see what species are best represented.
• Canada is well represented with a record count of 2082086. I'll post
record counts for the Polar bounding box area of interest to the Polar
scenario list shortly.
• You can do your own exploration through our data portal at:

climate is still advancing,
– Address interoperability arrangements for decision support
tools and predictive models used around the globe to
support policy and management decisions.
