V5.0 of INPHO’s Photogrammetric System

INPHO (Germany) has updated and integrated their software into a complete, perfectly tuned and integrated system. MATCH-AT 5.0, MATCH-T 5.0, DTMaster 5.0 and OrthoMaster 5.0 are released at one time, along with the new ApplicationsMaster 5.0. This module serves as the common core of the V5.0 system for project set-up and administration. All V5.0 applications are sharing a new common project file V5 containing all project related parameters, including cameras. Highlights of the versions 5.0 are: MATCH-AT 5.0 (for automatic aerial triangulation) comes with significantly enhanced matching strategies, especially for imagery from digital frame cameras. New tie point patterns and... (read more)

Creating a Satellite-data Integration System

The Importance of International Standards
CEOP (Coordinated Enhanced Observation Period) is currently working on an integrated global water and energy-cycle observation system for scientific and civilian use. One challenge is the creation of a satellite-data integration system able to combine a multitude of data stemming from a diversity of distributed systems. Data retrieval and combination requires high-performance distributed data-management and archiving systems. But the key is specification of metadata, for which international standards are indispensable. The prerequisites for developing a Satellite-Data Integration System (SDIS) are, next to specification of metadata, data discovery and data integration, geocoding service and data quality control, and standardisation of image-service...

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...

JACIA Workshop

The JACIE (Joint Agency Commercial Imagery Evaluation) team, comprising representatives from the National Aeronautics and Space Administration, the National Geospatial-Intelligence Agency, the U.S. Department of Agriculture, and the U.S. Geological Survey, is organising the sixth annual Civil Commercial Imagery Evaluation Workshop. The 2007 JACIE workshop will be held on 20–22 March 2007, at the Fairfax Marriott at Fair Oaks in Fairfax, Virginia (USA). This year’s workshop will focus on calibration, characterisation, and validation information and associated applications of civil, medium- and high-resolution commercial imagery used by the government. Attendees who wish to make oral or poster presentations concerning the incorporation... (read more)

Laser Scanning Technology Challenged

Shortcomings in Spatial Documentation of Heritage Sites
In this month’s Insider’s View Prof. Heinz Rüther puts some critical points on the shortcomings of laser-scanning technology in the spatial documentation of heritage sites. We invited manufacturers of laser-scanning sensors and software to comment on his challenging observations. Nearly 70% of the companies responded (ten in total) and seven felt qualified to reply: Optech, Riegl, Leica Geosystems, 3rd Tech, Visual Learning Systems, TopoSys and I-SiTE 3D Laser Imaging. We thank all respondents for their time and effort. Critical observations made by Prof. Heinz Rüther include the following. (1) The processing time of laser-scan data can be up to ten... (read more)

Magellan DG14 RTK GPS Board

Magellan (France) has introduction the DG14 RTK which offer high-end precision in a low-cost GNSS unit. The DG14 RTK from Magellan is a cost-effective, sub-metre GNSS (GPS and SBAS) and Beacon receiver. In the DG14 RTK, BLADE, Magellan's new proprietary GNSS processing technology, incorporates ranging and carrier phase signals from satellite-based augmentation systems (SBAS), such as WAAS, EGNOS & MSAS in the RTK computation. An embedded beacon receiver provides sub-metre differential positioning, when SBAS corrections are not available.   DG14 RTK customers can choose from a fixed centimetre solution or a "flying RTK" decimetre solution. Because it offers an optimised... (read more)

Laser Technology Unveils TruPulse 360

Laser Technology (CO, USA) has released TruPulse 360, which combines an integrated compass, inclinometer and distance laser that delivers mapping-grade accuracy and the ability to shoot from any angle. The internal circuitry provides 3-axis monitoring of the earth's magnetic field and uses LTI's proprietary TruVector compass technology and calibration algorithms to produce the best possible azimuth accuracy, regardless of the instrument's orientation in physical space. The TruPulse 360 can be tilted, rolled or even used upside down, and it will still measure the correct azimuth in the direction that the user is viewing, allowing the ultimate freedom to ‘shoot from...

Leica HDS 3000 in the Lab

Verifying Terrestrial Laser Scanner Quality
To the user the terrestrial laser scanner (TLS) is a black box; measurement procedure and data processing are treated as classified. Vendor provided technical specifications are reliable but may be inadequate, while verification is complicated. Using Leica HDS 3000, the authors developed and tested a new method for verifying the quality of TLS data. Surprisingly, the angular accuracy of the system appeared ten times better than specified. One of the most used measurement principles for terrestrial laser scanners (TLS) is the spatial polar method: distances are measured by a pulse or phase distance meter and the two perpendicular angles determined...
