We finally talked to Dr Liping Di at GMU Laboratory for Advanced Information Technology and Standards (LAITS)

GeoBliki and GeoBrain will be joined at the hip as part of the OGC OWS-4 and ESTO AIST concerted effort led by Dan Mandl, at NASA GSFC.

As part of the OWS-4 demo, GeoBrain will provide a BPEL workflow to process EO1 hyperspectral data and generate custom data products for an end-user. LAITS will also provide a WCTS (Web Coordinate Transformation Service) to transform the Eo1 GeoTiff from UTM to WSG84.

A GeoBrain BPEL workflow will connect the EO1 SOS, WCTS, WPS’s from WUSL CAPITA and UAH Earth System Science Lab. A user will receive a notification from our Pubsub service as a GeoRss feed when the data is available.

We intend to have this in-place for the December 4-5 OWS-4 demo to support a Humanitarian Assistance/Disaster Relief scenario.

Here is a basic GeoBliki Users guide. in PDF

We just moved to a new TextDrive data center. We think the move went well. Please let us know if you see anything strange.

This example is provided by Kari Hoijarvi from WUSTL.

Download IronPython from http://www.codeplex.com/Wiki/View.aspx?ProjectName=IronPython

Save the following code into a file called sos2.py

to run the code:

  ipy
  >>>import sos2
  >>>sos2.test()

The sos2.py file:

Basic authentication in Ruby example.

This is using Ruby 1.8.4 which may be installed:

Windows: http://rubyforge.org/frs/?group_id=167

OSX: http://hivelogic.com/articles/2005/12/01/rubyrailslighttpdmysqltiger

Example XML to pass to the SOS is found http://eo1.geobliki.com/sosdemo

post_it(xml)


 def post_it( xml, user = "bob", pass = "test")
    url = URI.parse('http://eo1.geobliki.com/sos')
    req = Net::HTTP::Post.new(url.path)
    req.basic_auth(user, pass)
    req['Content-Type'] = "text/xml"
    req.body = xml
    @response = Net::HTTP.start(url.host, url.port){|http|
      http.request(req)
    }
    puts @response.body     

  end
