Innovation versus quality
by Clare van Zwieten, EE Publishers
 Collaborative data collection, more commonly known as crowdsourcing, has taken off. Traditionalists question the quality of this data but where its strength lies, particularly in the mapping world, is in the ability of enthusiastic volunteers to provide specific details on areas that aren't covered by commercial or public sector mapping organisations...

Land governance in support of the global agenda
by Prof. Stig Enemark, past president of FIG
 International development over the last 10 to 15 years in the area of cadastre has been remarkable, leading towards a more holistic understanding of land administration in support of sustainable development. Recently this has developed further into land governance in support of the global agenda such as the Millennium Development Goals... ( more) |
Surveying on a moving vessel
by Mark Newling, Tritan Survey
This article looks at some of the problems when surveying and scanning on a floating ship using examples experienced while surveying a pipe-laying vessel in the Cape Town docks. These problems relate firstly to the movement of the ship in relation to the earth's gravity... ( more) |
Using tide gauges to monitor long-term sea level change
by John Hannah, University of Otago
When tide gauge records are examined in order to determine the long-term trends in sea level it is typical for a single number representing the derived trend, to be quoted. However, there appears to be a widespread ignorance as to the fragility of tide gauge records and hence the accuracy... ( more) |

Managing solar effects in GNSS operations
Information by Edwin Danson, C&C Technologies
Every eleven years or so, the sun goes through a cycle of change from minimum activity, through a maximum and back again. As the sun approaches its maximum, the heightening of solar activity generates electromagnetic disturbances that impact here on Earth... (more) |
