  • Proliferation of GPS-enabled Smartphones Spurs Growth of Global Location-based Applications Market

    The global market for location-based applications is poised for rapid growth, as the mass adoption of global positioning system (GPS)-enabled smartphones is encouraging developers to introduce numerous advanced applications, says market research agency Frost & Sullivan.

    New analysis from Frost & Sullivan finds that indoor connectivity, augmented reality, big data and wearable devices are the key technology trends likely to fuel the uptake of location-based applications. Location-based technology and data can then be combined to facilitate the development of smart spaces in every city and community.

    “Location-based application developers have so far focused on the development of outdoor applications due to the adoption of GPS positioning in smartphones,” noted Frost & Sullivan Information & Communication Technologies Research Analyst Shuba Ramkumar. “However, as individuals spend more time indoors, there is a need to roll out indoor location-based applications that capitalise on various functionalities such as mapping, navigation and geo-fencing.”

    According to the announcement, augmented reality technology could also be used to make location-based applications more interactive. Further, the widening ecosystem of wearable devices such as Google Glass and Samsung Galaxy Gear infuses technology into the daily lives of individuals, widening the scope of context-aware applications. However there are several challenges restricting the growth of the location-based applications market. The lack of standardisation in indoor positioning technologies such as Wi-Fi, sensors and Bluetooth is complicating the development of indoor applications. Location-based application providers will need to wait until wearable device manufacturers address the issues of limited battery life and dependence on smartphones for outdoor connectivity.

    Frsot & Sullivan reports that market participants also find it difficult to monetise applications due to the absence of a clear business model. In this scenario, application developers should seek to identify new sources of revenue. They can expedite market expansion by establishing contracts with indoor venues to provide customised applications, and by working with wearable device manufacturers to create related applications.

    “Stakeholders should work together to identify the most reliable and accurate indoor positioning technologies that can steer the indoor connectivity market forward,” said Ramkumar “The In-Location Alliance is one such initiative formed by market participants to discuss and resolve issues concerning indoor positioning technologies.”

  • Proteus Provides Satellite-Derived Bathymetric and Seafloor Maps for Military Exercise

    Proteus FZC, a provider of satellite-derived mapping solutions, has delivered accurate bathymetric and seafloor classification maps for a joint UK-France amphibious military exercise on the Island of Corsica. In the pilot managed by the UK Hydrographic Office (UKHO), Proteus partnered with DigitalGlobe to derive accurate bathymetric measurements and identify four seabed types to a depth of 12 meters from multispectral satellite imagery without ground control.

    “We completed the Corsica coastal marine mapping project at about one-tenth the time and cost of traditional sonar or LiDAR,” said Proteus CEO David Critchley. “Because the data is derived exclusively from satellite imagery, we leave no environmental footprint and face no airspace restrictions.”

    For the joint military operation, the British and French armed forces requested detailed information about water depth and the submerged seabed along specific sections of the Corsican coastline so that amphibious military vehicles could be launched from larger vessels anchored offshore and safely landed on the island’s beaches. The custom maps created by Proteus were used by the military to select precisely where the landings would occur.

    “The vertical accuracy of our bathymetric maps was verified at 10-15 percent of water depth,” said Critchley. “If ground truth data were available, the measurements would have been accurate to a solid 10 percent of depth.”

    Working with eight-band multispectral image data with two-meter resolution collected by DigitalGlobe’s WorldView-2 satellite, the Proteus-led team achieved the bathymetric measurements in Corsica’s Mediterranean coastal zone to a total depth of 12 meters. In a separate processing procedure, the team also extracted four critical seafloor types from the imagery – sand, rock/debris, vegetation and mixed seabed.

    Since 2011, Proteus has been producing seafloor survey and seabed classification projects using multispectral satellite imagery. The product generation technology that can be carried out in a fraction of the time and cost of traditional methods. These mapping projects have been delivered for environmental, oil and gas, marine biology and other coastal zone applications in Europe, the Middle East and Caribbean. Derived products have high accuracy, meeting the requirements of engineering, environmental monitoring and strategic geospatial planning applications.

    The project was written up in the January/February 2013 issue of Hydro International magazine.

  • CoreLogic Releases Annual Natural Hazard Risk Summary and Analysis

    CoreLogic2013Hur

    CoreLogic released its annual Natural Hazard Risk Summary and Analysis detailing the most significant natural disasters that struck the United States in 2013. The report provides an analysis of the impact of hurricane, flood, tornado, wildfire and sinkhole events over the course of the year, as well as a summary of potential risk from natural hazards in 2014.

    Compiled by CoreLogic hazard scientists, the report summarizes the property and structure, geographic and financial impact of natural disasters across the U.S. over the course of the year.

    “Many predicted that 2013 would be a record year of catastrophic destruction, but the number of natural disasters that typically cause widespread destruction, mainly hurricanes, wildfires and tornadoes, were far less than anticipated and in comparison to last year’s record-setting hazard seasons,” said Dr. Thomas Jeffery, senior principal scientist for CoreLogic. “Interestingly, one natural hazard that tends to receive very little attention took center stage in 2013 as three separate sinkhole catastrophes took place in Florida. Though massive damage and loss of life from sinkholes is uncommon, this year’s events were large enough disasters to draw significant media coverage, raising public awareness of the true risk associated with this often-overlooked hazard.”
    Among key findings, the CoreLogic 2013 Natural Hazard Risk Summary and Analysis notes:

    Hurricane
    • There was little hurricane activity in 2013. With only 13 named storms, just two reached hurricane classification and hurricane totals were both lower than pre-season predictions and disproportionately lower than previous hurricane seasons dating back to 2003.
    • None of the storms in 2013 had a direct impact on the U.S., and as such, there was relatively minor damage related to Atlantic storms.
    • The first official hurricane of the year, Hurricane Humberto, formed on September 11, just three hours short of setting the record for the latest formation of the season’s first hurricane.

    Flood
    • Flooding in the U.S. was moderate compared with recent years, partly due to the low number of Atlantic storms and the related coastal flooding. National flood losses for 2013 are expected to total approximately $2 billion.
    • The most significant flooding event of the year was a September storm in Boulder, Colorado, which caused the damage or destruction of more than 19,000 homes and resulted in record-setting levels of precipitation and flooding affecting 17 Colorado counties.
    • To identify the metropolitan areas located in transitional areas between high and low elevations and therefore at risk for catastrophic flood events, CoreLogic developed the first National Catchment Slope Map in 2013, illustrating the structural hydrology of the U.S. landscape.

    Tornado
    • Total tornado activity in 2013 was at a historic low, with 229 fewer tornadoes than any year in the past decade as of October 25. Nonetheless, the severity of numerous Oklahoma storms and an unusually violent wave of late-season storms affecting 12 states in the Midwest were no less catastrophic.
    • Following three days of storms with numerous tornado sightings, on May 20 an EF5 tornado swept a 17-mile path through Moore, Oklahoma, killing 23 people, injuring 377 others, and causing an estimated $2 billion in damage.
    • The widest tornado ever recorded, 2.6 miles at its widest point, struck El Reno, Oklahoma in early June, resulting in eight fatalities and nearly $40 million in damage.

    Wildfire
    • The number of wildfires and total acreage burned in 2013 were lower than both the 2012 season and the 10-year average. Excluding California, Colorado, Idaho and Washington, which perpetuated their 10-year average in terms of acreage affected, the Western states saw dramatically lower wildfire activity than in recent years.
    • Several individual fires caused massive destruction, including Arizona’s Yarnell Hill Fire, which destroyed 8,400 acres and 129 homes, and Colorado’s Black Forest Fire, which burned 14,000 acres and destroyed or damaged over 500 homes and resulted in a total property loss expected to exceed $300 million.
    • The Rim Fire, on the outskirts of several densely populated communities approximately 100 miles east of San Francisco, was the third largest fire in California state history, destroying only 11 homes but burning over 257,000 acres, including much of the Stanislaus National Forest and Yosemite National Park.
    • Probable increase in fuel load in wildfire areas, as well as persisting drought conditions in California, Nevada, Arizona, New Mexico, Texas, Utah and Colorado, indicate potential for increased wildfire risk in 2014.

    Sinkhole
    • Three unusually severe examples of sinkhole activity in Florida captured public attention in 2013. A sinkhole in Seffner, Florida caused a tragic death in March when it formed underneath a man’s home. A tourist villa was heavily damaged when a 100-foot sinkhole formed near Clermont, Florida, and a 90-foot wide by 50-foot deep sinkhole resulted in the collapse of two homes in Dunedin.
    • The CoreLogic sinkhole database currently recognizes 23,000 identified sinkholes, suggesting that sinkhole activity and subsequent property damage will continue to be a substantial risk across the nation and for Florida residents in particular.

    “Though there have been fewer billion-dollar catastrophes over the course of 2013, history has demonstrated time and time again that a temporary reprieve from natural disasters cannot and should not be expected to continue into the future,” said Jeffery. “Going into 2014, it’s important to remember that hazard-driven property damage and loss can and does occur each year, and with the cyclical nature of some of these events, this year should be considered fair warning that next year will likely see a return to the higher average numbers of damaging natural disasters.”

    According to the announcement, CoreLogic generated findings for the Natural Hazard Risk Summary and Analysis using the company’s comprehensive parcel database and natural hazard risk analytics, as well as data from reputable sources, such as the National Climatic Data Center, NIFC, EQECAT, Inc. and the National Weather Service.

  • Non-Profit Seeks Help with GIS Project for Costa Rica through Crowdsourcing

    20131013143401-Fullscreen_capture_10132013_33021_PM

    Geoporter, a non-profit focused on leveraging advanced mapping technology to empower communities to address burgeoning problems from within, has launched an Indiegogo crowdsourcing campaign to help support continued work and expansion. Funds will be used to provide resources to current projects in Costa Rica, while allowing the team to establish new operations in other areas globally.

    Besides financial donations, the group is seeking serviceable digital cameras, GPS units, and laptop computers — worn but working well.

    The organization uses GPS-driven technology to map behaviors in a community, allowing them to better define problems, develop and implement solutions, and evaluate the effectiveness of their efforts for continual improvement. The technology can be used to address a wide variety of problems, from tackling trash build up in the area to monitoring whale patterns in order to facilitate more sustainable tourism practices. In Costa Rica, the Geoporter team worked to map mosquito larva and water treatment to help reduce the risk of exposure to dengue fever.

    “It’s exciting and rewarding work,” said co-founder Anita Palmer. “We’re going into areas where we can make a real difference in the everyday lives of people through the power of data analysis. What’s more, we’re helping to reverse trends that would otherwise have regional and, in some cases, global implications.”

    gI_65702_Kids-trash-gpsGeospatial mapping is not new, but it has traditionally been executed by teams of experts in the aftermath of a crisis. Geoporter’s approach is a proactive one, where experts move into communities as challenges are developing so they can effect change before there’s a real problem. Still, building and sustaining a team of experts would have been cost-prohibitive, so Geoporter decided it would try something radical: teaching people within these communities to use the technology themselves.

    “We started by training adults and youth,” explains Geoporter Director Amy Work. “Now, children in the area are taught how to use the technology in and outside of school. We have eight-year-olds navigating commercial-grade geospatial mapping technology like Esri ArcGIS Online better than some of the professionals I’ve known. The lessons they’re learning today will not only enable them to take ownership of their communities, but provide them with skills they can leverage through adulthood.”

    Geoporter is hoping to use the IndieGoGo campaign to raise the funds necessary to continue their work in Costa Rica, and are looking to expand into other areas over the course of the next year. Donations will go towards funding technology, educator travel and living expenses, and community staffing.

  • Leica Geosystems Launches BIM Field Trip Solutions for Contractors

    LeicaBIM

    Leica Geosystems Inc. announced new BIM Field Trip solutions to help contractors extend the value of building information modeling (BIM) into the field and connect field information back to the model in the office.

    Tailored to fit any stage of BIM adoption in concrete layout, MEP layout, quality assurance, renovation/retrofit, and operations/maintenance as-builting applications, BIM Field Trip includes customized packages of hardware and software that make it easy to move from 2D to 3D workflows to achieve common BIM goals such as reduced rework, increased predictability and higher profitability, the company said.

    According to the announcement, the new BIM Field Trip solutions take full advantage of Leica Geosystems’ established precision measurement technologies, such as the trusted iCON robot 50 robotic total station and popular 3D Disto laser measurement tool, as well as the latest innovations. For example, the revolutionary “BIM One Box” Leica Nova MS50 MultiStation, introduced in June 2013, offers full-featured total station layout capabilities that can handle BIM layout points from Revit, AutoCAD or virtually any other BIM or CAD program with ease, while also integrating real-time delta reporting for quality assurance checks and high definition laser scanning capabilities for capturing as-built point clouds to be compared with the as-designed model.

    The BIM Field Trip solutions are available in three basic levels to help companies bridge the gaps in their BIM processes.

    BIM 101 is the simplest way to get started with digital layout using paper or CAD files as a starting point. Easy-to-use, highly accurate tools such as the 3D Disto, iCON robot 50, and DISTO handheld laser measuring devices combined with intelligent, intuitive field and office software create an easy on-ramp to BIM for preconstruction as-builting, concrete layout, MEP layout, preconstruction as-builting and quality assurance. (Learn the basics of digital layout in the BIM Learning Center.)

    BIM 102 provides an intermediate-level solution to help contractors improve their BIM workflows. For preconstruction as-builting, industry-leading ScanStation high definition laser scanners capture existing building conditions in the form of near photorealistic, highly accurate point clouds that can be used directly in Revit for faster and more accurate modeling. For digital layout, high-precision iCON robot 50 robotic total stations combined with intuitive field software creates a “paint-by-numbers” installation in the field that reduces errors and provides a higher level of predictability of project outcomes. For MEP and interior BIM applications, the 3D Disto combined with specialized MEP software further simplifies and streamlines interior layout. And for preconstruction as-builting, layout and quality assurance, the innovative new “BIM One Box” Nova MS50 MultiStation performs robotic layout with ease while the field software tracks the layout locations. When quality control checks are performed, any deviations are identified in real-time with a BIM delta report and can be easily scanned with the same device, producing point clouds that are automatically oriented and positioned so they flow back into the model perfectly aligned. This substantially reduces post-processing so teams can focus on comparing field data with model data to avoid rework in the field.

    BIM 103 is for contractors that are experienced in BIM and want to take their capabilities to the next level. Hardware solutions such as the innovative multistation, ultrafast high-definition laser scanners and high-precision robotic total stations are combined with full featured field and office software to create advanced 3D workflows that streamline and optimize preconstruction as-builting, construction layout, and quality assurance as-builting. What’s more, the innovative “BIM One Box” multistation introduces a new era of versatility in BIM workflows with the ability to use a single instrument for preconstruction as-built point cloud data capture, replicating highly accurate BIM layout points in the field, and then high-definition laser scanning for quality assurance as-builts for comparing with as-designed models to create a complete 3D BIM lifecycle.

    At each level of the BIM Field Trip, hardware and software selections are tailored to the needs of the contractor and are easily scalable from one level to the next to provide practical solutions to common BIM challenges.

    “For many project teams, the benefits of BIM stop in the office; there simply hasn’t been a total solution for BIM as-builting and construction layout that connects all the dots from the model to a real-world jobsite and then from the jobsite back into the model,” said Cathi Hayes, BIM Business Manager for Leica Geosystems. “The new BIM Field Trip solutions from Leica Geosystems close the gaps by connecting the digital world to the real world. This allows companies at any stage of BIM adoption to take advantage of improved workflows.”
