Ground Zero WTC ::: 9/11 Maps & Debris

Excerpt from "9/11 Debris: An Investigation of Ground Zero" by Matt Nelson (2018, PDF - 68MB, 265 pages - images links updated)

Aerial photography (see also here) wasn't able to see through the persistent smoke until September 15, with LIDAR (Light Detection and Ranging - see video clip from "World Trade Center: Rise and Fall of an American Icon" [History, 2002] or read some at That first LIDAR image (source, credit EarthData International) wasn't seen by authorities until Sept. 17. This delay for access to the images at the Emergency Mapping and Data Center (EMDC) thereafter was next-day/morning ("Engineering and Organizational Issues Related to The World Trade Center Terrorist Attack Volume 3, Emergency Response in the Wake of the World Trade Center Attack: The Remote Sensing Perspective," by Charles K. Huyck and Beverley J. Adams, ImageCat, Inc., for The Multidisciplinary Center for Earthquake Engineering Research (MCEER), June, 2002, p. 20). With LIDAR a laser fired from above was able to map topography accurate to 6 inches in height (History, 2002). Depending on equipment, altitude, and speed of the aircraft, the resolution - or distance between points measured by the laser - varied between 6 and 15 feet for EarthData, and a bit more for NOAA (Charles K. Huyck and Beverley J. Adams, Ibid., p. 18). Flyovers were done regularly (daily in September, with only a few exceptions -- see the imaging timeline [together with more comprehensive details in Charles K. Huyck and Beverley J. Adams, Ibid.]). The main purpose for this and other high tech imaging was to create maps to help search & rescue experts, firefighters, police, ironworkers and others climbing in the pile. With the help of Dr. Sean Ahearn, director of the Center for the Analysis and Research of Spatial Information (CARSI), it was also possible to chart areas of possible collapse (Maddalena Romano, "Charting Ground Zero exhibit opens in Soho," GeoNews, Volume 15, number 3, February 2002). Finally, the images provided more general information, like changes in the volume of debris. (More on that shortly.)

The Sunday Sept. 23 New York Times ran an article titled "From 5,000 Feet Up, Mapping Terrain for Ground Zero Workers," which featured a large LIDAR image taken Sept. 19. Compare to another taken Sept. 23 (source, credit NOAA/U.S. Army JPSD) and another, high resolution image dated 9/17 (credit EarthData, source: Nov. 17, 2010 NYC OEM MAPS FOIL). Much more on mapping Ground Zero can be found at The George Washington University website. Notice the importance of the U.S. Army Corps of Engineers, who in the quote below attest to the importance of LIDAR.

"GIS maps are created from aerial photos taken daily at the World Trade Center site. A light detection and ranging system takes photos that scan the area to pinpoint exact elevations." - Justine Barati, "Corps Assists FEMA and New York City with Mapping Capabilities," Yankee Engineer World Trade Center Edition, U.S. Army Corps of Engineers, New England District. Dec., 2001. p. 9.

Of course more conventional photography was used. Compare aerial images for these days: 9/13, 9/15, 9/17, 9/19, 9/22, 9/26, 9/30, and 10/3 (source: Nov. 17, 2010 NYC OEM MAPS FOIL, credit EarthData). It's a shame black and white was used by EarthData (See Charles K. Huyck and Beverley J. Adams, Ibid., Section 3.1.3. "Problems").

Additionally, aerial thermal imagery helped keep rescue workers safe from hot or even molten metal and underground fire (see GeoNews," Vol. 15, Number 1, October 2001). Images and data from the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) recorded Sept. 16 and later can be found at the USGS website (see also this USGS page). Underground fires burned for more than 3 months, despite the USGS claims that hotspots were nearly eliminated by Sept. 23. (image source) See, for example, "Metal of Honor: The Ironworkers of 9/11" by Rachel Maguire, Spike TV, 2006. Additional examples and much more description of the rubble can be found below. AVIRIS provided the most detailed thermal data (including temperature), but other instruments were also used. For instance, see an image from the "tripod mounted Raytheon Nightsight Palm IR 250 thermal camera, carried aboard a Navajo Chieftain aircraft." (Charles K. Huyck and Beverley J. Adams, Ibid., p. 21.) These images could be combined with 3-D LIDAR (Ibid., p. 32.), but not in the detail provided by AVIRIS. Sadly, "[a]lthough AVIRIS temperature readings were released to the FDNY, this key information was not received by any of the mapping centers." (Charles K. Huyck and Beverley J. Adams, Ibid., p. 39. Also see image below.) [Note there was a mapping center for Urban Search and Rescue at the Jacob K. Javits Convention Center in midtown, which focused on Ground Zero alone. The EMDC at Pier 92 {after being moved from the NY Police Academy Sept. 14, after 2 days} worked on the entire area. Third, there was FEMA working at Pier 90. {Charles K. Huyck and Beverley J. Adams, Ibid., p. 6.}]

AVIRIS also had the ability to measure and help track airborne pollutants, primarily the carcinogen asbestos. See the USGS PDF document "USGS Environmental Studies of the World Trade Center Area, New York City, after September 11, 2001." Unfortunately, there were "considerable time delays" in getting resulting info. "These compositional results were not released until the 27th September, by which time the risk posed to response crews by airborne contaminants had abated." (Charles K. Huyck and Beverley J. Adams, Ibid., p. 26.) This important issue is discussed in the chapter "Dust."

Similar high tech gear was employed by the U.S. Army Communications Electronics Command (CECOM) Research, Development and Engineering Center (RDEC): "the Night Vision and Electronic Sensors Directorate's (NVESD) Night Vision Imaging Spectrometer (NVIS) sensor suite, which includes a high resolution imager." Aerial shots were able to get thermal readings and more. Like AVIRIS, NVIS could identify elements. "The NYC health dept. was looking for ways to identify and create maps of materials in the entire debris field. . . Unfortunately, the complete pulverization of materials in the rubble made it unfeasible to attempt to unmix and identify specific materials using a spectral signature library of construction materials." ("Airborne remote spectrometry support to rescue personnel at 'Ground Zero' after the World Trade Center attack on September 11, 2001," Chris Simi, Anthony Hill, Henry Kling, US Army CECOM RDEC Night Vision and Electronic Sensors Directorate, et. al. [emphasis added])

Let's move on to the usefulness of high tech imaging as it relates to the original purposes of this paper. A significant amount of attention was given to measuring the debris mass and volume. The number of tons of debris removed was often mentioned in reports about Ground Zero. .. "The volume of debris was calculated through GIS analysis. This helped the city determine how much debris was removed. Images were compared daily to determine changes in the site." - Vince Elias, et. al., "New York District in the Red Zone," The New York District Times, U.S. Army Corps of Engineers, NY District. Vol. 26, No. 5, Fall, 2001. p. 8.

G.I.S. stands for Geographic Information Systems (see for example "Mapping the Hazards to Keep Rescuers Safe," New York Times, Oct. 4, 2001). The "systems" constituted software, hardware, and people. Quickly visit New York City's makeshift OEM headquarters (that replaced WTC 7, destroyed on 9/11) in a Sept. 19 NBC News report. Notice the GIS on the wall behind Director Richard Sheirer (at 0:27).

Authorities at FEMA (and the New York City Office of Emergency Management, who was already working at Pier 92 on the Hudson River in preparation for a bioterrorism exercise planned for 9/12/2001) wanted to know how long the recovery operation would take, and about how much it would cost. Since the NYC OEM headquarters at WTC Building 7 had "collapsed" 9/11 afternoon, Pier 92 conveniently became headquarters. A FEMA Disaster Field Office was established at the adjacent Pier 90 (source - note Pier 91 is on the East River). Debris management experts from the U.S. Army Corps of Engineers arrived (Allen Morse and others) and coordinated with both FEMA and city officials (source - USACE). Resulting reports that detailed the calculated debris mass were published and quoted often during the "cleanup."

Unfortunately their process of translating LIDAR data into weight/mass measurement has not been fully explained. Some mathematical formula not unlike cargo freight being weighed dimensionally? The resulting numbers have never been independently verified (or clarified for that matter), and so have become the subject of much speculation. Leading geographer Sean Ahearn of CARSI has not provided input on this detail; nor has FEMA or the U.S. Army Corps of Engineers. "On Sept. 23rd, 12 debris specialists started debris monitoring. USACE completed its part of the Debris Operations Plan on Sept. 23rd and turned the operations over to FEMA at the DFO [Disaster Field Office at Pier 90]. The official joint estimate of the total debris amount was released at 1.2 million tons." ("Role of USACE at the WTC Response Operations" []) But what did that estimate include? Later in this book the physical measuring devices such as scales, barges, and dump trucks will be scrutinized for input, but only after gaining an understanding of the behavior of those driving the drivers.
