It
wasn’t that way initially. Twenty days after the explosion, I received an
e-mail from Andrew (Drew) Stephens, founder and director of The GIS Institute,
a nonprofit organization that offers GIS support, planning and training around
the world. Stephens was heading to the incident command post (ICP) in Houma, La., a small town
60 miles south west of New Orleans,
and he invited me to join him. Within hours, my bags were packed, and my
journey had begun.
Stephens and I arrived at the ICP just after midnight. We obtained our badges,
cleared security and, after a brief tour of command center, proceeded toward
the GIS Lab. On double duty was Waypoint Mapping’s Devon
Humphrey, geographic intelligence officer and resident National Incident
Management System (NIMS) expert. NIMS was developed as a systematic approach
that allows coordination of multijurisdictional entities within all levels of
government and private sectors to work together in times of crisis to reduce
the loss of life, property and harm to the environment. Humphrey explained the
existing state of the geospatial data and the massive amounts that were
pocketed across the ICP. He emphasized the need of the Louisiana parishes and federal agencies to
be able to expeditiously use GIS functionality in their planning and response
initiatives. He was certain that ramping up an enterprise GIS within the
framework of this major incident was achievable. The team was determined to
make it work.
Taming the Wild GIS
Part of the focus of the GIS Lab was to analyze and display two aspects of the
spill--protection strategies and oil extents, which are loosely referred to as
the booms and plumes. Booms are fence-like barriers that are placed in the
water to round up and contain oil, allowing skimmers and other methods to
capture it. As a first line of defense in protecting the shoreline, the booms
received a lot of attention. The plumes showed the outlined polygons of the
extent of the oil spill--the mixtures of oil, sheen and emulsion that became
known as the “giant blob.”
Imagery-derived boom and plume data were provided daily by the National
Geospatial Intelligence Agency, and other data were incorporated into the day’s
latest common operational picture (COP). Tactical situation maps, map books and
various other custom maps were also produced by our team.
Initially, these data were scattered on laptops, flash drives and desktop
computers. A store-bought external hard drive was used as a temporary file
server as plans for new workstations and an ArcGIS Server churned through the
system. Everyone was working 14 to 18 hours a day, seven days a week,
scrambling to get their hands on data and provide the necessary information for
their respective sections; there was little time to consult. Some order had to
be brought to the geospatial system, and our team was the one reponsible to
make it happen.
The GIS Smoke Jumper Team, as we became known, comprised experts from all
across the United States--talented NIMS-certified individuals who dropped
everything to lend their support. Experience on the team ranged from 5 to 20
years and included project management, process, workflow, mapping, database,
mobile, programming, and imagery expertise. What was ingenious about the team
was that we were able to switch roles as the need arose. It was not uncommon
for a data guy like me to be found producing map books at 0600 hours. Training
was crucial, and shadowing each other helped to fill the gaps.
We faced notorious red exclamation marks littered across ArcMap MXDs as we
siphoned scattered shapefiles and lone personal geodatabases into our temporary
holding area on the infamous T:\ drive, then to an in-lab ESRI SDE box, and
eventually to a dedicated United States Coast Guard server. Many map sources
had to be repointed several times. This scenario became my inspiration to
create an adaptive workflow process that would establish a consistent rhythm
for the team.
As the Data Czar in me took over, I began unraveling our processes and
diagramming our map products and services beginning with the source data and
the times we received them, and ending with a deadline for the finished
product. All entities were embedded on a 24-hour timeline. In an environment
with no time to spare, processes needed to take on a revolving and adaptive
characteristic. Adhering to this structure enabled rapid assessment and
enhancement of our daily work flow. Hence, as the dynamic environment of the spill
changed, so did our workflow and, ultimately, our processes. This modus enabled
the team to consistently meet the demands of all our service areas.
Making a Difference with Data
Though the push for maps forced many of our resources into mapping mode, the
importance of the getting the data and process correct was recognized by our
leadership team. We leveraged cutting-edge imagery from NGA as well as key
technology and resource support from ESRI. It was upon ESRI’s new ArcGIS 10
platform that we were able to masterfully execute our objectives to provide
timely and accurate geospatial analysis and information to the various agencies
involved.
The GIS Smoke Jumper Team was able to provide more than 150 layers of data, an
ArcGIS Server implementation, ArcGIS Mobile deployment in a cloud, and a flex
viewer that continued building functionality. An enterprise environment was
ramped up in a matter of days, and a methodology for capturing, storing
synchronizing, replicating and disseminating spatial data was instituted in a
time frame that would typically take a year or more to set up, test and deploy.
NIMS kept our focus on the incident and chain of command and, as a result, our
structure and purpose were unwaveringly focused on the ecological disaster and
not concentrated on the development of a corporate GIS.
When considering the vast extent of the damage caused by the oil spill and the
11 lives lost in the oil rig explosion, our efforts seem small. But in GIS,
accurate and organized data are vital to gaining key insights and making
informed decisions. In that sense, I’m appreciative that I have been able to
play a supporting role.
Prepared to Respond
The National Incident Management System (NIMS) provides a systematic, proactive
approach to guide departments and agencies at all levels of government,
nongovernmental organizations and the private sector to work seamlessly to
prevent, protect against, respond to, recover from, and mitigate the effects of
incidents. But it isn’t just a system for first responders. Anyone can take
advantage of free NIMS training courses offered by FEMA to become prepared to
respond in the event of an emergency. For surveyors with mapping and data
management expertise, having NIMS training can allow you to be a valuable and
even vital part of recovery efforts wherever disaster strikes.
