Emergency Response and GIS

Posted by Dave Smith On 6/14/2007 07:23:00 AM 0 comments

One of the other events which will be happening concurrent to the ESRI Conference is the SONS 07 event - "Spill Of National Significance", which will replicate a major catastrophic event - to include simulated release of oil, hazardous material, and/or other associated threats to health and safety. This year's event will take place in the midwest, replicating an earthquake along the New Madrid fault zone.

Through our work with USEPA, we will be among the participants in this event, as we did for Hurricane Katrina, supporting the effort through our own GIS staff at the USEPA Emergency Operations Center. The two main stakeholders and participants on the environmental side are USEPA and USCG, along with FEMA, state, regional and private sector participants to support the response as appropriate.

It's good to see these events take place, and it no doubt will give us many more new lessons learned and opportunities to refine response. The bottom line still comes to being proactive, in terms of GIS preparedness, as opposed to reactive. With regard to availability of information on impacted facilities, we will no doubt be in better condition than we were for Katrina, but many of the other pieces are still lacking. Specifically, there is still little transparency or availability of realtime or near-realtime data, when it comes to assessing response capacity and many other pieces.

Here, we should go back to HSPD-5 which deals with communications and interoperability, and examine how well our GIS assets work together, and how well they support standards, how well-documented they are to allow users to make informed decisions regarding the data.

Closely affiliated and associated with this is HSPD-8 for preparedness - which comes along with a host of other questions - how current, scalable, flexible and robust is your GIS data, and does it address the need? For example, how many burn units are immediately available in a 100-mile radius right now, how many pieces of fire apparatus are available right now - with the right now being key. In looking at a dozen or so counties nearby, I see almost 500 fire stations, almost 200 law enforcement offices, and nearly 200 emergency medical providers. Yes, they participate in surveys and report in data, but how timely is it? Now consider that Pennsylvania has 67 counties, and the scale of the problem magnifies greatly. Say your EOC is impacted, loss of power, loss of communications, otherwise rendered inoperable. Can you cascade your operations over to a COOP site and continue seamlessly?

Here in Pennsylvania, we have many gaps, overlaps and stovepipes for data and communications flow, and many points of failure, from local to local, local to county, county to county, local to state, county to state, between state agencies, local to fed, county to fed, state to fed, and fed to fed. I can't think of any one of these which genuinely works seamlessly with the next. This is what we have been referring to as the gap of pain, and something for which we have a concept and team already up and running to address.
The February 2007 snowstorm, which caused widespread damage and notoriously left hundreds of motorists trapped on Interstate 78 for 20 hours, still remains a major fiasco here in Pennsylvania, with solutions still thoroughly unadressed politically, fiscally and bureaucratically. On the other hand, technologically, we can address the data, communications and preparedness issues. This is something that we have been looking at quite closely ever since 9/11, investing a lot of time and thought into, and something I will be running through again, considering the SONS exercise. It's time to act and become proactive, and to break through the stovepipes and fiefdoms.

Google Earth exposes violence in Darfur

It warms my heart to see that a headline story today is in how Google Earth has been working to expose the violence and bloodshed in Darfur.

This part of Sudan has been suffering horrendously in the midst of conflict, with denial from the Sudanese government - and thanks to the efforts of the folks at Google, the violence has been put front and center, with imagery depicting destroyed villages and lives, people displaced, and worse.

From one of the news articles,


Using high-resolution imagery, users can zoom into Darfur to view more than 1,600 damaged or destroyed villages, providing what the Holocaust Museum says is evidence of the genocide. Sudan's government denies that genocide is taking place.

In addition, the remnants of more than 100,000 homes, schools, mosques and other structures destroyed by janjaweed militia in Darfur, Sudanese forces and others are visible.

"
When it comes to responding to genocide, the world's record is terrible. We hope this important initiative with Google will make it that much harder for the world to ignore those who need us the most," said Holocaust Museum director Sara Bloomfield in a statement.

As we saw with Rwanda, we cannot afford to sit by idly and do nothing.

As an aside, as Google Earth has also been in the hot seat in the news of late, I recently was contacted by Kenneth Wong of Cadalyst Magazine "GIS Tech News" regarding the recent Google Earth controversy on Katrina.


I will certainly be one to defend Google Earth. As a federal contractor doing GIS work for Katrina response, we were long aware of their dedicated Katrina site, and to them I give kudos for providing infrastructure and imagery for the relief effort. Congressional inquiry? Not appropriate, and I certainly hope Google is spared this. However while I said "much to do about nothing" I also soundly will echo Adena Schutzberg's comment that it all the more points up the need for metadata for live data services and online mapping.

Coastline Erosion

Posted by Dave Smith On 3/05/2007 12:12:00 PM 0 comments

The Times Picayune has a good article discussing the dramatic, accelerated loss of coastline in Louisiana due to erosion:

It took the Mississippi River 6,000 years to build the La. coast. It took man 75 years to wash away a third of it. Experts agree we have 10 years or less to act before the loss becomes irreversible.


Also striking for me was the accompanying photo essay, which included photos of an NGS benchmark, which has long since lost integrity and become surrounded by water and ghost trees, where formerly there was shore...
