Mobile Lidar Systems Today and Tomorrow

The Promising Future of Mobile Mapping and Laser Scanning
Mobile Lidar systems (MLSs) are used with increasing frequency for three-dimensional (3D) mapping applications along various corridors because of their extreme ease in capturing high-resolution 3D topographic data. This article examines the current state of the mobile Lidar system market before looking ahead to the future scope for mobile mapping and laser scanning, including potential challenges that lie ahead. Mobile Lidar systems are frequently used for 3D mapping applications along various corridors because of their extreme ease in capturing comprehensive high-resolution 3D topographic data at normal speeds. An MLS observes a corridor and nearby objects in the form of their... (read more)

Highest Ever Resolution

A Delta 2 rocket carrying the GeoEye-1 satellite lifted off on Saturday 6th September 2008 at 11.50am from Vandenberg Air Force Base, California. Weighing 1,955kg, the satellite can capture every piece of the Earth up to every two days at approximately 10.30am local time. This interview presents further details and strategic considerations.<P>   Sixth September 2008 must have been a very exciting day - what were your feelings on reaching this milestone? GeoEye first made history in September 1999 with the launch of its sub-metre resolution Ikonos satellite, then the highest-resolution commercial earth-imaging satellite. This title now goes to GeoEye-1.... (read more)

Smart Parking in Megacities

App Based on Mobile Mapping Point Clouds and Imagery
Did you know that you can waste a week or more per year hunting for a parking space in busy cities? Nowadays, smart parking apps offer a much-needed answer to the problem – and mobile mapping point clouds and imagery are core ingredients of the solution. Besides saving time by guiding you straight to an available spot close to your destination, smart parking apps also reduce unnecessary fuel consumption, air pollution and greenhouse gas emissions. One such app is AppyParking by London-based AppyWay. The AppyParking app allows users to see all on-street and off-street parking areas, restrictions and operating hours.... (read more)

RADARSAT-2 To Be Launched in 2005

Features and Applications of Canada’s Second SAR Satellite
RADARSAT-2, Canada’s second Synthetic Aperture Radar (SAR) Earth observation satellite will offer users imaging flexibility and increased data information content, ensuring continuity of all existing RADARSAT-1 beam modes along with powerful new capabilities, from 3m resolution to flexibility in selection of polarisation. The satellite is due to be launched from Vandenberg Air Force Base in California in 2005. RADARSAT-2 is Canada’s next-generation commercial Earth observation Synthetic Aperture Radar (SAR) satellite, the follow-on to RADARSAT-1, launched in 1995. The new satellite has been designed with significant and powerful technical advancements and provides the fulcrum of a programme representing a unique partnership... (read more)

Adapting 3D Laser Scanning for the Surveyor

Meeting Specific Needs to Increase Productivity
3D laser scanning is a powerful measurement technology for obtaining 3D coordinates of object points at a speed of up to 5,000 points per second. But surveyors see lack of scanner versatility and unfamiliar workflow as limiting factors. Today, increased portability and robustness and adapted workflow enable surveyors to easily incorporate 3D scanning into their portfolio. A short learning curve allows for increased productivity and creates new business opportunities. Today 3D laser scanning is based either on phase-shift or on time-of-flight measurement. Phase-shift technology works by sending a laser beam with a sinusoidal wave to the centre of a rotating... (read more)

Mobile Road Mapping in Cameroon

Supporting Water Utilities Renewal
In Yaoundé, Cameroon, little cartographic data of the road network, public assets and utilities is available. To efficiently renovate the city’s drinking water network, mobile mapping technology was used, taking extra care to ensure planimetric accuracy near the equator. It provided the GIS data for the road maps needed for the project planning. The experimental methodology used – with GIS and web suites integrated in the network construction project at all stages – was a good fit with the current African context and offers promising potential for future projects. The Cameroon Water Utilities Corporation and Water Cameroonian are jointly in... (read more)

Landslide Hazard Mapping in Austria

Using GIS to Develop a Prediction Method
In Austria many manmade objects such as roads and buildings are vulnerable to landslides caused by heavy rainstorms. These result from climate change and changes in geological structure. Using GIS, the authors analysed the characteristics of landslides and developed a prediction method. Recent events have demonstrated how the method can support decision-makers in urban and regional planning. Population growth and changes in land-use policy result in increased hazard risks. For example, lack of risk awareness causes governments to allow the building of houses in potential hazard zones. As yet, little is known about the distribution of landslides. Figure 1 shows...

Trimble Dimensions 2007

Welcome to the Third Dimension
Trimble Dimensions 2007 took place from 5th to 7th November 2007 at the Convention Center and Events Center, Mirage Hotel, Las Vegas, US. There were some 2,200 participants, up from last year's total of two thousand. With the usual format of plenary keynote sessions, technical sessions and a trade show, the event sported the theme “Transform Your Business with the Connected Site”.<P> Trimble president and CEO Steve Berglund kicked off the conference, saying 'Welcome to the third dimensions'. His phraseology was intentional; the conference would focus on three dimensions, paralleling developments in the geospatial world. Pointing out how far technology... (read more)

An IFSAR Quality Management System

Meeting DEM and Ortho-imagery Specifications
Interferometric Synthetic Aperture Radar (IFSAR) is emerging as a highly cost-effective 3D mapping technology. Digital elevation models and ortho-rectified radar imagery are core commercial Intermap Technologies products using its airborne IFSAR based STAR technology, the list of applications for which is continually growing. Quality control and assurance ensure consistent data quality. Data quality has become a matter of escalating interest amongst the geospatial community. Data providers must thus ensure their data products meet specifications; quality must be built into the production process so that data consistently and predictably meets expectations. A rigorous Quality Management System (QMS) needs to be designed... (read more)
