LOCATION NEWS FROM THE WEB LOCATION ECOSYSTEM 1. Maps may decide who rules mobile’s future http://bit.ly/128K4hB January 2, 2013 Advanced location-based services linked to maps are at the forefront of mobile technology and could play a critical role in which corporate behemoth emerges on top, Rolfe Winkler writes. Apple’s disastrous mapping application reinforced Google’s sizable lead in the arena, and Google is expected to release a sophisticated predictive tool to provide wireless-device users with information before they even request it. 2. Why indoor mapping is the next frontier http://bit.ly/XRn3c7 December 12, 2012 Indoors is the next mapping frontier for location data, writes Matt Ball. Up-front costs can be high and real-time location tracking can be a challenge, but businesses that take the time and effort will be leaders in indoor marketing. For businesses such as manufacturing plants and hospitals, such maps can improve safety and efficiency. 3. Geospatial projects found to save time and money http://bit.ly/14rlHKL January 16, 2013 A review of nine geospatial projects by Kim Geomatics revealed that the projects have many benefits, such as cost savings, better market intelligence and increased productivity. Geospatial data can be expensive, however, which might lead to some databases being out of date, but using Web-based databases can help solve that problem, according to Kim Geometrics President Bob Ryerson. INDUSTRY APPLICATIONS 1. How location data helped break the Petraeus scandal http://bit.ly/YDAxy4 November 14, 2012 Former CIA Director David Petraeus’ affair was discovered in part because of location data encoded in a series of alleged harassing e-mails that his mistress sent to another woman. “Email, information-wise, says as much about its sender as its receiver. The messages’ metadata told investigators what they needed to know, even if they weren’t looking to know it in the first place,” this article notes. 2. Online atlas offers precinct-level view of 2008 election results http://bit.ly/WAuC72 November 7, 2012 Researchers at Stanford and Harvard have joined forces to create an online “Election Atlas” giving a precinct-level view of the 2008 election results. The tool lets researchers glean information about the demographic and geographic foundations of President Barack Obama’s winning coalition, showing how Obama and John McCain split rural and suburban voters. 3. Disney introduces bracelet technology to make parks even friendlier http://bit.ly/X7t2ZF January 9, 2013 This spring, Walt Disney World will launch a program that will allow participating customers to bypass entry turnstiles and use rubber bracelets encoded with credit card data to enter and buy items inside the park. The bracelets are part of a vacation management system called MyMagic+, which is part of a larger effort to make the park easier for guests to navigate. BUSINESS AND STRATEGY PLANNING 1. Why location data will be a gold mine to marketers in 2013 http://bit.ly/128K4hB January 2, 2013 Location-based technology on smartphones will be a boon to marketers in 2013, Neal Leavitt writes. Marketers can target ads and offer instant discounts to customers who “check in” at specific locations. Marketing tech firm Tabbedout caters to users who don’t like to broadcast their location by offering applications that allow users to search businesses by ZIP code. 2. How retailers set prices using customer location data http://bit.ly/WAuR1T December 26, 2012 Some retailers, such as Staples and Office Depot, are using customer location data to set prices when a customer shops online. Prices can be different depending on where a customer lives and how close that location is to a competitor. 3. How the cloud takes GIS to the next level http://bit.ly/14rlHKL January 16, 2013 Geospatial information systems running in the cloud gives everyone across an organization quick access to location dataIMAGING NOTES // WINTER 2013 // WWW.IMAGINGNOTES.COM without worrying about installing software or calling in a GIS professional, Krairop Luanguthai writes. “It provides easy-to-use 9 workflow to enable not only GIS professionals but typical users to convert their own spreadsheet data and create a beautiful map on their own,” Luanguthai said.

  • Bathymetric LiDAR SANDY’S COASTAL IMPACT Detailed and accurate charting of the sea bottom along coastlines is vital for environmental monitoring and reme- diation, shoreline construction, and coastal navigation. Each of these activities requires reliable depth data for planning and management purposes. However, sonar-equipped vessels conducting hydrographic surveys cannot navigate very shallow or rocky coastal areas or narrow inlets with high tidal ranges, and topographic airborne LiDAR mapping (ALM) systems cannot penetrate the water. Airborne LiDAR bathymetry (ALB) fills this gap: as a supple- mentary survey method, it provides a seamless transition between mapping the land and charting the sea. EDITOR’S NOTES All Superstorm Sandy — technically, a post-tropical cyclone by the time it made landfall along images except the last the coastline of the United States on October 29 — affected 24 states, including the entire Eastern two are of point clouds collected with an Optech Seaboard from Florida to Maine, causing particularly severe damage in New Jersey and New CZMIL sensor and are York.

  • FIGURE 3. Sandy Hook, New Jersey FIGURE 4. Ellis Island, New York 4 complementary technologies for coastal mapping, explains Jennifer Wozencraft, the center’s director. It is made up of USACE, the U.S. Naval Oceanographic Office, the Remote Sensing Division of the National Geodetic Survey of the National Oceanographic and Atmo- spheric Administration (NOAA), and the U.S. Geological Survey’s Coastal and Marine Geology Program. “We own and operate, through contract, LiDAR bathymetry and airborne remote sensing sensors for coastal mapping for the USACE and the Navy, and then with the other agencies we do research and development to advance hardware and software and to demonstrate the different applica- tions of the data that we collect,” says Wozencraft. The center funds companies to develop hardware for it — primarily airborne sensors. “It all started with the SHOALS program, back in the late 1980s,” Wozencraft recalls, referring to the Scanning Hydrographic Operational Airborne LiDAR Survey. “One of the main goals of that program was to develop a capability that could be commercialized to make it more widely available for the USACE and our other partners.” Immediately following Sandy, JALBTCX was tasked by USACE’s North Atlantic Division to collect LiDAR data for the districts that fall within that division’s jurisdiction. The center used its own planes to collect the data for the New York District and contracted with private compa- nies to collect data for the New England District, the Philadelphia District, and the Norfolk District. The flights took place November 11-24, as soon as the center had been able to gather the requirements from the impacted areas. “The primary require- ment,” says Wozencraft, “was classified topographic 3 LiDAR data as well as bare earth DEMs generated IMAGING NOTES // WINTER 2013 // WWW.IMAGINGNOTES.COM26

  • ArcGIS Also Used for Analysis DATA ACQUIRED USING USACE’S COASTAL ZONE MAPPING AND IMAGING LIDAR (CZMIL) was also analyzed in ESRI ArcGIS to lend insight into storm-driven coastal geomorphology change, and to produce information products critical to USACE emergency response requirements. In the past, workflows for vector, lidar, and imagery have been collected on a project-by-project basis. ArcGIS enables users such as USACE to manage these massive collections of data for more than one purpose and extend the content into 3D. These 3D models, lidar, and imagery can be cataloged and distributed for access in multiple collections as either raster data, raw elevation data, or Esri webscenes. If data is not necessary, it can be easily filtered out for a clean representation. By managing massive 3D models and point clouds with ArcGIS, data can be more easily visualized and analyzed. 7 8 F IG U R E 7. This is the bridge at Mantoloking (CR-528) in New Jersey.

  • If Old McDonald had a farm today, he could manage it from his laptop computer and map it with an application on his handheld device. When he is out in the field, his tractor’s guidance system could know its position to within less than an inch, turning his planters and sprayers on and off accordingly. A boom height control system would make sure that his sprayer did not hit the ground and a yield monitor on his combine would measure the exact volume of his harvest, in real time. Soil moisture sensors networked via cellular modems, soil density sensors on his planters, and infrared crop health sensors on his tractor would gather a wealth of data that his agronomist would use to prepare a prescription map for the next season. In a few years, that data stream would also include aerial imagery collected by his unmanned aerial vehicle (UAV) and his tractor would also be running unmanned as a robot in the field. If a chick, duck, turkey, pig, cow, cat, mule, dog, turtle, or farm hand got in its way, the tractor’s radar collision avoidance system would recognize it and stop. The most widely used term to describe this complex suite of technologies is precision agriculture, and the uptake is exploding. Most new tractors and implements are sold with factory-installed global navigation satellite system (GNSS, which includes the better-known GPS) receivers and a variety of sensors. Reversing a long-standing trend, kids who were born and raised on farms are now returning there after college, because the work is much more intellectually challenging and less manual labor-intensive than it used to be.

The advent of the OpenWeb and a seemingly endless amount of new science data have the potential to do for the computational social sciences in the 21st century what other measurement tools did for the natural sciences of the 20th century – advancing further human understanding and human welfare. Big Data will be central to that pursuit. “Data is the new oil” is a phrase coined by Clive Humby and embraced by the World Economic Forum in 2011 as it considered data as an economic asset like oil. Every day, we create 2.5 quintillion bytes of data – so much that 90% of the data in the world today has been created in the last two years alone. (IBM) These data come from everywhere: hard sensors used to gather information, the social web, transaction records, and cell phone GPS signals, to name a few. The amount of such data is big and by every account growing exponentially. These facts, however, give no hint to where the largest growth is, or comparatively speaking, where the greatest rewards lie for researchers. It is difficult to believe that data are increasing uniformly. IMAGING NOTES // WINTER 2013 // WWW.IMAGINGNOTES.COM34

  • The Next 15–20 Years SECURE WORLD FOUNDATION FORUM This past December, the National Intelligence Council, an of the worldwide challenges we face that element of the Department of National Intelligence (DNI), issued Global Trends 2030, can be met with more effective use of a voluminous report assessing the state of the world and trends from a geopolitical space technologies, particularly geospatial perspective. The DNI oversees and coordinates the work of the Central Intelligence ones. Unfortunately, the world community Agency, the National Security Agency, and other entities charged with collecting and falls far short in using space systems interpreting information that might affect U.S. national security. effectively to tackle these challenges, many Global Trends 2030 (http://www.dni.gov/index.php/about/organization/national- of which could improve the chances of intelligence-council-global-trends) is well worth reading, not only to bring us up to reaching sustainable Earth environments. speed regarding the interplay of the various geopolitical influences that affect the Among the report’s broad conclusions United States and the rest of the world, but also to explore the possible futures that we is the likelihood that as a result of increased all might encounter.
