Maps Revolutionised By 3D System
A new way of producing maps with lasers to create three-dimensional images has been tested in Bournemouth, England.Ordnance Survey has used the system to produce a detailed computerised map of the town centre.
The map is the result of a three-year trial and the agency says it could revolutionise the way maps are produced and used.
Every metre of the town was captured using land-based and aerial surveys with high-accuracy lasers.
The lasers, which use 700 million points of light, plot detail including terrain, vegetation and buildings. The road network and aerial imagery were added to complete the maps.
Here's a video of the 3D map of Bournemouth.

The chief difference between aerial photography and aerial survey is that whereas the former can include obliques and photographic reconnaissance, aerial survey is a very precise operation involving photogrammetry.

Thanks for this information. It added more my knowledge about lidar survey ... Thanks again.

Does it mean that in term of photogrammetry, its better to choose aerial survey than aerial photography ?
