Geodata: Limitations in Current Concepts

  The first of the nine Societal Benefit Areas (SBA) of the Group on Earth Observation (GEO) is Reduction and Prevention of Disasters. The SBA listing and high ranking reflects not only the increasing significance of disasters to society, but also that remote sensing, or geoinformation science in general, is very well suited to providing adequate information. Significant attention for disaster is not new, but we are seeing subtle change and developments in the perception, with the focus shifting away from the disaster itself and towards risk. Limitations As a result, the term ‘disaster management’ is being increasingly replaced by... (read more)

Planetary Cartography: Current Activity and New Ideas

The idea of including a new direction in ICA cartographic research, towards the mapping of planetary bodies, was raised by Russian cartographers at the seventeenth International Cartographic Conference (ICC) held in Barcelona in 1995. Members from Germany, USA and Canada supported the proposal. A working group was formed and a full Commission on Planetary Cartography was approved during the 1999 Ottawa conference. Limited Activities One of its major goals is the harmonisation of international planetary cartographic efforts. This does not mean a ‘homogenisation’ of planetary maps, where everything looks the same, but rather the fostering of free interchange of ideas... (read more)

The Current State of the Art in UAS-based Laser Scanning

Airborne Laser Scanning with a UAS
Airborne laser scanning (ALS) offers a range of opportunities for mapping and change detection. However, due to the large costs typically associated with traditional ALS, multi-temporal laser surveys are still rarely studied and applied. Unmanned aerial systems (UASs) offer new ways to perform laser scanning surveys in a more cost-effective way, which opens doors to many new change-detection applications. What are the differences in suitability between the two main types of UAS platforms – fixed-wing systems and rotorcraft – and what is the current state of the art in UAS-compatible laser scanning systems? Read on to find out. (By Antero Kukko, Anttoni... (read more)

Onboard Galileo Atomic Clocks

Current Status and Performance
The European Commission and the European Space Agency have approved the Galileo GNSS programme. Two experimental satellites will be launched in late 2005 or early 2006. Atomic clocks are critical for satellite navigation. After more than ten years of development and an overall budget of € 30M, two onboard clock technologies have been qualified. The author considers their current status and performance. Galileo is a joint initiative of the European Commission and the European Space Agency (ESA) for building a state-of-the-art global navigation satellite system (GNSS). Galileo will provide a highly accurate, guaranteed global positioning service under civilian control and... (read more)

Global Ortho Project

Continuous, Consistent and Current Coverage
Microsoft’s Global Ortho (GO) project aims to capture the entire continental United States and Western Europe at a spatial resolution of 30 centimetres, using UltraCamG digital aerial cameras. The GO project produced the first imagery in August 2010 and has to date captured 46% of the area and published 2.21km2. The entire project is scheduled for completion by June 2012, to be followed by a three-year refresh cycle. The author discusses the GO project, as well as features of the UltraCamG and the new UltraCam Eagle digital aerial cameras. The latter was launched as a commercial offering in May 2011....

Power Line Infrastructure Management Support

Southern Mapping Company (SMC) completed several power line surveys in Africa, using Lidar to derive a digital terrain model and digital ortho-photos to obtain a map of the specific areas. Aerial surveying saves valuable time, money and resources for these tasks. "The processed data has been handed over to our clients and can now be used to evaluate their current power line infrastructure, therefore aiding them in effectively managing current- and planned infrastructure. This information proves vital in assessing environmental hazards adjacent to power lines," says Peter Moir, Chief Executive Officer of SMC.A key goal of the overhead power line... (read more)
