Geospatial Apps Help Temper Mother Nature's Fury

Here is a very good write up in Federal Computer Week regarding our current work with the Namibia Flood Pilot.  The prototype can be openly access on our Campaign Manager website (which is unfortunately restricted to most users).

Sensor Web Project Generating Buzz and Benefiting Society

FYI: A "Did You Know" on your Sensor 3G work (attached) was presented and distributed on Feb 23rd at the Headquarters Earth Science Directorate Staff

2-Factor Authentication for SensorWeb

Posted by Patrice Cappelaere Tue, 29 Dec 2009 03:48:00 GMT

Securing transactional RESTFul OGC Web Services is a challenge but can be done using a hybrid OpenID/OAuth protocol (see OGC OWS-6 interoperability demonstration).

To increase the security assurance level beyond level-1, you need to use more than one authentication factor such as: something you know (password) and something you have (keyfob).  Our openid server is currently being upgraded to support Verisign Identity Protection (VIP) and VIP Access using Mobile Credentials (free for end-users).

If you register a credential in your profile, a security code can now be used in addition to a password to gain access to the SensorWeb services.  A security code can also be used to delegate user authority to consumer applications such as workflows to access services on your behalf.  Credentials will become mandatory to gain access to satellites and UAV tasking request over the web.  There will still be an air gap between users and assets but, at least, user identity will be known with very high confidence.

Our goal is to demonstrate that it can be done simply, cheaply and RESTfully.

Proposal For A NASA Virtual Currency to Demonstrate Value

Posted by Patrice Cappelaere Thu, 17 Sep 2009 20:50:00 GMT

September 17, 2009, in the Wall Street Journal, Andy Pasztor writes:

"PASADENA, Calif. – NASA’s No. 2 official on Wednesday vowed to provide taxpayers "better value" by focusing on environmental goals and promoting science education"

Problem is: How do we demonstrate value for "free" data?  For a particular program, one could build a model to demonstrate that value could be generated (see NOAA Portfolio Analysis).  This could end up being very costly. The other issue is:  how accurate or realistic would those models be?

A better way is to provide an environment that can enable the emergence of sustainable ecosystems powered by an american concept: A "Free" Market approach to value. Let the user communities place value on the NASA data they want to aquire or assets they want to task, and even compete for that data or assets if necessary.

What better demonstration of "Value"?  What a better way to get communities involved and point to us what they "value"?

The idea is to create a NASA virtual currency or NASA dollars that could be used to access data or task NASA assets when needed.  Users would need to demonstrate value creation and would receive equivalent NASA purchasing power as they see fit at no "real" cost to the users.  The useage of this virtual currency would be a great indicator of value as perceived by the user community.  When some users or some community can justify increased creation value, they would receive more NASA dollars.  If you cannot justify value creation, you would simply become second class citizen.  No need for an enforcer.  Let the Free market decide. 

This could also help with Basic Science Research.  Let’s have scientists justify value for their research too.  They would be getting hints on user needs after all.  This could be done various ways: from measuring their scientific paper publications and counting the references to those papers to measuring a "Return On Investment" based on science applications and direct technology infusion that eventually will lead to market growth.

This would be a major technology break-through driven by pure economics.  Isn’t this the American Way after all :).  Not that easy but not rocket science either.  I am sure that several universities would love to provide guidance to this new frontier for NASA.

Here is an idea for a name for the new currency (since it does not cost anything): 

PubSubHubBub: Real-time Event Notifications For Our OGC Services

Posted by Patrice Cappelaere Sat, 12 Sep 2009 16:35:00 GMT

Leveraging another Google feat with the newly minted PubSubHubBub protocol or PSHB, interested users can now get real-time notifications when new products from EO-1 are available.  Rather than polling our server at:, consumers can subscribe for that feed at:

They can enter their own callback to receive changes as it happens.

This capability is also now built-in Feedburner, Google Alerts and Google Reader.  More on TechCrunch

The same feed is available on FeedBurner:

But why would you subscribe to it there?  unless you are a human!

Feel free to use Google Reader and add that feed to your favorites.
