Workflow Technology to Benefit Africa

Posted by Patrice Cappelaere Mon, 24 Nov 2008 14:16:00 GMT

The NASA EO-1 team has been very busy integrating some new technology as part of an ESTO grant.  Our mission: Deliver quickly, relevant information to local end-users during disasters.  Unfortunately, we have had several national and international disasters to support recently.  Floods and landslides in Kenya have recently affected more than 300,000 people (14 Nov 2008 OCHA Situation Report).

NASA is already engaged in Africa with the new SERVIR program in partnership with USAID (Press Release 08-307 and article from Nicholos Wethington in Universe Today) and the Regional Center for Mapping of Resources for Development in Nairobi.

This last week was the first time we were able to turn around imagery in less than 24 hours of a declared emergency and automatically provide an imagery data feed directly to local users in the field.

With the help of Dr. Brakenridge at the Dartmouth Observatory, we were able to correlate the data with MODIS information.

MODIS Actuals

Many products were automticaly generated using a workflow based on Open Source Software (OpenWFEru), assembled as a feed and published.  Access to the data was immediate through a feed reader such as Google Reader or Firefox using the Sage addon.  These level 2 products are available as KMZ files for visualization using Google Earth.

Part of our current research is to publish the workflows themselves to allow end-users to reprocess the data on-demand as they deem necessary, right from the same feed reader.  For example, pan-sharpened products (10m resolution instead of 30m) could be generated on the fly and made available in a similar manner.  They would require more time to download as they can be quite large (250MB or so).




AIAA Infotech Presentation

7 - 10 May 2007 Doubletree Hotel Sonoma Wine Country Rohnert Park, California.

Here are the PDF slides of the presentation… paper should be available soon too. There was a lot of interest in UAVs and Spacecraft collaboration for WildFire Management.

Coming Next: Custom Data Products Tailored To Your Specification!

We know how to mass produce and disseminate data. We can even alert you when it is available based on your subscription.

But We cannot stop there.

With new capabilities such as Hyperspectral imagers from space or UAV’s, we opened up Pandora’s box. There is now an infinite way of looking at a particular scene. Are you interested in Fire, Water, Plume/Clouds, Contaminants, Oil Slicks…?

Are you Red Cross, USCG, Forest Service, USDA, First Responder or even NORTHCOM? This might be for you!

Our next challenge is to customize data products to your requirement and deliver it just-in-time for free (if we can).

This might include tasking a satellite or UAV! This might include using the expertise of scientists from NASA JPL or GSFC or even tap into one of many universities cooperating on this project (UMD, WUSTL, UAH, GMU…)

What is the secret sauce we are working on?

OGC standards… of course. and GeoRSS

Think Workflows (but not BPEL:). Thanks John for your support and a great product with OpenWFEru

and down the road: BPMN…XPDL 2.0?…but that’s another post.
