The UCL Virtual London folks have been asked by the Ordinance Survey folks to remove their model from Second Life. Dr Andrew Hudson-Smith, the team leader of the Virtual London group at UCL writes:
"Our Virtual London model in Second Life has been removed from the collaborative environment at the request of the Ordnance Survey.
The research is currently 'pending license clearance' as the Ordnance Survey are 'uncomfortable' with the use of the data.
Details on the work currently unavailable are in the post below, we are reserving comment at request on this one, but i guess you know our views...
Three Dimensional Collaborative Geographic Information Systems (3DC/GIS) are in their infancy, Google Earth opened up the concept of three dimensions to the mainstream but issues with data copyright, the inability to effectively tag data to buildings and the asynchronous nature of the platform have limited developments.
Second Life however provides a synchronous platform with the ability to tie information, actions and rules to objects opening the possibility of a true multi-user geographical information system. It has been notoriously difficult to import 3D data into the Second Life but at CASA we have managed to import our Virtual London model of 3 million plus buildings into a scrolling map. The map is built from prims that 'res' our of a central point to build accurate models based on Ordnance Survey MasterMap with height data supplied by InfoTerra."
