Reflections of Singapore – Part 1

Thursday, November 4th, 2010

During our recent travels to Singapore as exhibitors at the GSDI conference, the weather was characteristically warm and humid, and produced heavy cloud cover every hour of every day. No surprises there. However, towards the end of our stay, the city recorded the worst smog since 2003. This was the result of farmers burning off the harvested crops on neighboring Sumatra, mixed in with the warm humid air. The smog was so dense it was difficult see from one side of the street to the other. It occurred to me how difficult it would be to obtain standard geospatial imagery in these conditions; conditions which present no problem for GeoSAR. I also couldn’t help but notice the triple-canopy foliage everywhere that hid so many core infrastructure features. Why in this day of advanced remote sensing technology should a project be severely stalled due to dense vegetation or adverse weather or atmospheric conditions? Users need to be able to obtain accurate geospatial data – both imagery and 3D terrain data – through tropical triple canopy foliage in less than ideal weather conditions. These are a few of the mapping challenges that GeoSAR has successfully overcome.

Night or day, cloudy or clear, GeoSAR collects and delivers the core datasets required to populate your NSDI. Traditional sensors need sunlight for operation, which substantially limits flying time to daylight only and then only when the angle is right, and cloudy and stormy conditions can keep sensors grounded for days, or even weeks. Even panchromatic satellite imagery fails to collect during harsh atmospheric conditions, where clouds and smog hide the earth from these high orbits. Satellite data from radar sensors, while penetrating the clouds offer a much reduced resolution in comparison to GeoSAR; and let’s remember that resolution is an important factor when determining the overall geospatial needs of any NSDI programme.

Night time, bad weather, cloud cover, tree canopy, snow…all of these conditions translate to impossible mapping mission, however GeoSAR tackles these challenges and shows that mapping the impossible is not only possible, but can be done with unprecedented speed and accuracy, anytime, anywhere.

So, are you ready to utilize the world’s largest commercial airborne remote sensing platform? Drop us a line and let us know your needs and we’ll see if we have a solution that fits.

GeoSAR for Spatial Data Infrastructure (SDI) Source Data

Wednesday, October 6th, 2010

GeoSAR continues to show its global reach by making a strong presence at upcoming events around the world. Fugro will be present at the 1st annual Latin American Remote Sensing (LARS) conference in Santiago, Chile October 4th- 8th and will continue the trade show trail joining forces with colleagues from Fugro’s South East Asia offices for the annual GSDI conference being held in Singapore October 19th- 22nd. At GSDI 12, Fugro will be presenting on Spatial Data Infrastructure (SDI) and the advantages GeoSAR provides as a data source in equatorial regions. So what advantages does GeoSAR provide for countries located in equatorial regions that are updating or developing their SDI?

Many countries, large and small, developed or developing, have built what are called Spatial Data Infrastructures (SDI). Geospatial data is a key component in developing a SDI. Geospatial data can be collected from a variety of airborne platforms. However environmental conditions for countries located along the equator can make this data collection process a bit difficult. Consistent cloud cover and triple canopy foliage are a few of the main factors that contribute to the difficulty in data collection. Fugro’s GeoSAR is uniquely designed to conqueror these obstacles. GeoSAR is a dual-band interferometric synthetic aperture radar (IFSAR) system. With each pass of the aircraft, GeoSAR simultaneously maps both surface features (X-band) and bare-earth terrain (P-band). X-band penetrates through the cloud cover collecting all the surface features while P-band penetrates through foliage (as well as cloud cover) collecting the bare-earth terrain. GeoSAR X- and P-band orthorectified imagery and digital elevation models contain all the information needed to produce topographic and thematic mapping at standard 1:25,000 and 1:50,000 map scale.

From Snow to Sand: The Benefits of Dual-Band IFSAR

Thursday, April 1st, 2010

The conference trail grows longer! At last post, we had just returned from the Alaska Surveying and Mapping Conference in Anchorage where GeoSAR Project Manager Steven Shaffer presented the applications of dual-band IFSAR in arctic and sub-arctic environments. Snow penetration/mapping was part of that discussion. This week we are switching gears—rather dramatically—to the Map Middle East Conference in Dubai where last week GeoSAR Client Program Manager Caroline Tyra presented a paper on the ability of radar to penetrate sand for subsurface mapping.

The overall concept isn’t exactly new. Ground penetrating radar (GPR) technology, which utilizes radar bands in the UHF/VHF frequencies from hand-held or vehicular-based equipment, is a well established technique. It’s the use of remote sensing platforms for subsurface mapping that is gaining ground (no pun intended!). Using satellite and airborne methods, it is possible to provide wide-area coverage of subsurface hydrology and structures for use in mineral exploration and development, infrastructure design, and archeological research.

So where is the science? In the early 1980s, the hyper-arid Bir Safsaf region in southwestern Egypt was mapped using Shutte Radar SIR-A and SIR-B to detect geologic structures covered by layers of sand. Discoveries from that research included fossil river systems. More recent studies have shown the ability of very low-frequency radar, such as P-band, to penetrate depths of 15 meters or more depending on soil composition, radar incidence angles, and soil moisture.

Fugro EarthData has confirmed these P-band findings using GeoSAR during a mission over the Mojave Desert near Edwards Air Force Base. Among other things, the results revealed a mostly submerged geological formation. Subsurface mapping is an area we’ll continue to research given its many implications related to water networks, national security, and heritage management. It’s also one more way that we can help clients maximize the value of their GeoSAR data—by unlocking what we call, “the Power of P”.

Welcome to "The Location Age"

Thursday, October 1st, 2009

Geospatial isn't just for map geeks anymore. We've got personal navigation devices that dictate driving directions, smart phone apps that are as useful as they are fun, and GPS-equipped dog collars so Fido never gets lost again. Whether conscious of the change or not, consumers in the industrialized countries are now fully entrenched in "The Location Age".

But it's not the same story all over the world. In fact, many developing countries are struggling to update their most basic map inventories. How can this be? Providing answers to this question was a main goal of the recent National Mapping Organizations Industry Forum organized by GIS Development in South Africa. Serving as a prelude to the much larger Map Africa 2009 conference, forum participants were asked to share the vision and objectives of their organization, the challenges they face in realizing this vision, and their thoughts on the role of geospatial technology and the industry in achieving these goals.

Participants cited numerous obstacles to implementing effective programs. Voiced almost unanimously, however, was the misperception among policy makers that geospatial data is a luxury rather than a necessity. This notion is further complicated by a bewildering disconnect about the value of survey and mapping data to infrastructure development. This, despite the billions of investment dollars currently flowing into the region for infrastructure improvements…

These statements are dismal for sure, but many also noted a growing awareness of geographic information slowly penetrating up to higher levels in government. It also appears that some of the new data, software, and training resources available internationally are starting to reach local users. Public outreach will help strengthen this trend, as will sustained partnerships by private companies willing to help with the education effort through technology exchange. Decades-old perceptions don't change overnight, but Fugro, for one, is dedicated to the mission.

It's true: geospatial isn't just for map geeks anymore.

In Support of the Geospatial Revolution Project

Tuesday, August 4th, 2009

Last year, a good friend and former colleague, Karen Schuckman, told us about a new initiative to document the evolution of geospatial technologies in a documentary for public television. It sounded like a lofty goal at the time, but then it is unwise to underestimate Ms. Schuckman. In addition to her own long resume of accomplishments, she tends to surround herself with only the most capable of people. And so it comes as no surprise that the trailer for Geospatial Revolution Project, has been exceedingly well received among insiders and non-geospatial professionals, alike.

The trailer was first introduced in May at this year’s annual ASPRS conference. Since then, it has been getting play among a more varied audience—including Facebook members, YouTube watchers, and most recently, the U.S. Congressional Subcommittee on Energy and Mineral Resources Oversight. As reported by Got Geoint? and All Points Blog, the video was shown prior to last week’s policy hearing on federal geospatial management. If after watching the trailer, subcommittee members understood for the first time the true value of geospatial data, then we as a community owe a large debt of gratitude to the documentary’s contributors, funders, and production team.

Click here to check out the trailer and join us in spreading the word about this ground-breaking media project. For Fugro EarthData’s part, we look forward to contributing to the effort, which has the potential to make a huge impact on our field. As users continually embrace geospatial technology—including foundational datasets like IFSAR—now is the time to demonstrate where all this information comes from. After all, it’s not just the magic of Google Earth…it’s also what lies beneath.
