    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. 

http://computerworld.co.nz/news.nsf/news/open-source-front-end-for-environmental-data

    
    

    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?
