Image-based modelling is still the most widely used approach in building documentation and 3D investigations, but panoramic camera laser scanners are gaining in importance. They offer large fields of view,...

Imaging Earth from space has become normal business and the acquired data a commodity like any other. Earth-observation satellites are constructed and launched at conveyor-belt speed. On 27th October 2005...

Obstacle Clearance Limits (OCLs) are defined by the International Civil Aviation Organization to warrant safety around airports. However, as operational areas are not marked in reality but have complicated 3D...

Terrestrial 3D laser scanning will become the future standard tool for high-resolution 3D documentation of archaeological excavations, but its capabilities are still underestimated by professional archaeologists and providers of scanners...

The Open Geospatial Consortium, Inc. (OGC) and the Web3D Consortium have signed a memorandum of understanding to work together to cooperatively advance standards to support web-based 3D visualisation, modelling and...

GPS is good for perhaps 70% of surveying needs. Inertial Navigation is the forgotten friend of GPS. Traditionally complex and expensive, Inertial Navigation has become competitive, easy-to-use and cost-effective. Need...

On a map showing the countries of the world according to the size of their carbon footprint, the Northern Hemisphere is roughly twice as big as it is in reality...

Our interview with David Shell on the background to, benefits and consequences of Microsoft Corporation joining OGC as a Principal Member provided so many interesting points that we decided to...

CyberCity AG (Switzerland) has extended its library of European 3D city models with two impressive datasets: Paris and Florence. Paris 3D is a highly detailed 3D model of the city...

Terrestrial laser scanning combines a high level of detail with surveying accuracy for the creation of 3D-models of virtually any object. The technology literally opens up new dimensions and so...
