Please note that NIWA is also hosting a two day workshop with BoM staff looking at the SOS web service and time series data management, delivery & interoperability issues, immediately following the SISS workshop.
Cheers,

Hi Tim and list,
Yesterday I found out about the following:
Open source front end for environmental data
Research institutes implement open source platform for
environmental data sharing between agencies
Crown Research Institutes GNS Science, Landcare and National
Institute of Water and Atmospheric Research (NIWA) are working
together with the New Zealand Geospatial Office to open the flow
of environmental data between government agencies by harmonizing
the systems used for managing it.

Tim, are the portals that you describe in your email part of the
above cooperation?
It's really nice to see that we all seem to use a very similar Open
Source infrastructure. Here is a short summary of what some areas in
the BoM (including mine) are using extensively:
- OpenLayers
- ExtJS
- GeoExt
- MapServer
- PostGIS
- THREDDS (for OPeNDAP access)
Some work is being done on utilising GeoServer and GeoNetwork, but
not operationally yet AFAICT.
Besides that, we have some custom software in development that might
be of interest:
- BOM.Map: a 'framework' that brings OpenLayers, ExtJS and GeoExt
together in a way that allows to separate configuration (map and
user interface) from the application.
- A custom Python WMS service that generates contour plots from
gridded data sources (like OPeNDAP / netCDF files)
Ideally, I'd like to see both products become available under an OSI
approved license, but we're not there yet. Any interest from outside
the organisation might help us go in that direction... :-)
Anyway, I'd be very interested to see where we can find synergies.
Regards, Roald

Hi Bruce,
These technologies are definitely relevant to our areas of
interest as well.
I work for Landcare Research New Zealand. We are developing
geo-spacial portals, namely:
http://ourenvironment.scinfo.org.nz
http://smap.landcareresearch.co.nz
While Our Environment is not officially launched yet, but it
presents some of the features that we have implemented, all using
open source libraries and software.
David is in CC, who you might be interested in collaborating with.
I'm the front end web developer and developed all of the client
side (JavaScript) code and have done some work on the server side
print module (MapFish Print, where I am a committer) while other
members of the team administer the services and wrote some of the
services being used and necessary.
Additionally we use:
OpenLayers
GeoExt
ExtJS
jQuery
on the client side
and
PostGIS/Postgres
Java Restful Services
MapServer
MapFish Print
etc
on the server side.
Let us know if there are opportunities of collaboration.
Kind regards,
Tim

John,
We have a **prototype** that is currently not available
externally. We have a few 3rd party data IP issues to
resolve.
This prototype was a finalist at the V.SIBA spatial
excellence awards.
Development was jointly funded by both the Department of
Climate Change and Energy Efficiency as well as by the
Bureau of Meteorology.
In brief, we tested an enterprise grade spatial architecture
for providing access to climate and climate projections
related data.
The architecture is based around the use of Open Spatial
Standards, so that in the future, we can provide access to
data as well as portal type tools via open spatial standards
such as WMS, WFS and WCS.
The interface is based around the Weave Spatial Intelligence
/ Business Integration framework.
Other key components include:
Postgres
BIRT
PostGIS
MapServer
Thredds
GeoServer
I have been very impressed by the functionality and
performance of the open source components.
We tested realistic quantities of data covering the
Australian Continent (and beyond):
topographic data, based on the
Bureau’s GeoFabric data
20 years of Landsat Mosaic’s
covering Australia (GA)
9”, 3” and 1” DEMs
~900 gridded climate data sets
50 years of historical
Average Maximum Temperature grids (annual and
monthly)
10 years of Climate
Projections grids – Average Maximum Temperature
(annual and monthly)
Historical meteorological
observations data at ~30,000 stations.
Functionality includes seamless integration of:
Web Mapping capabilities
GIS type attribute searches
GIS type spatial overlay
functionality (e.g. point in poly, buffer etc)
Business Intelligence reports:
time series graphs from DB
and WFS.
time series graphs created by
drilling down through historical and climate
projections grids via WCS
a range of observations data
and data provenance related reports.
A time series animation
capability for viewing climate grids (via WMS)
I demonstrated the prototype to our peers at the
international OGC Technical Committee meeting in Boulder in
the US a few weeks ago. The approach that we took generated
quite a bit of interest and a couple of invitations to
present.
Like most organisations, we have funding issues and
competing priorities. I don’t anticipate that we will have
an operational variant of this prototype available
externally for a few years.
If you have read this far, you may be interested in
accessing Climate data via Open Spatial Standards, and/or
the prototype type of interface in the future. If that is
the case, please contact me via email so that we can start
building the Business Case for funding.
Also, if you are in Melbourne and would like a run through
and live demo, let me know and I’ll see what we can do
(bearing in mind that we’re in the middle of a major systems
migration).

Looks like the sort of tool that
should be coming out of the NCCARF program? What's the
closest equivalent in Australia?

This is very relevant for us.
