Topographical survey of 119 sites in only 12 days

PROJECT：代表英格兰高速公路区域提供119个地点的详细地形调查3
CUSTOMER：Sun Hill测量与工程有限公司
SOLUTION: Leica Pegasus:Two, Leica MapFactory
OBJECTIVE: 119 sites were surveyed in only 12 days, ahead of the final deadline, allowing traffic flow as usual. The network was not disrupted and no traffic management was required.

Area 3 is Highways England’s second largest network carrying around 10 per cent of the country’s overall traffic flows. It includes the M27, M3, M4, A3, A303 and the Hindhead Tunnel. The network provides the main link routes between several major towns and cities including Oxford, London, Reading and Swindon in the north, and Bournemouth, Southampton and Portsmouth in the south.

在2015年，基尔（Kier）接近并委托了Sun Hill的测量和工程，以代表英格兰公路区域3.进行119个地点。大型项目需要对车道和Verges进行详细的地形调查，每次调查均为600米，用于设计和设计，设计和verge量为600米。未来的更换和安装道路标牌，以使道路上的梯度更清晰可见。

Leica Pegasus:Twoand the mobile mapping process have revolutionised the world of surveying. Using the mobile mapping process and Leica Geosystems’ technology provided huge benefits to the Area 3 Highways England project. Access to all sites was left clear with no road closures required as the Pegasus:Two acts in the same way as any other public vehicle when collecting the 3D geospatial data.

In total, the surveyors travelled more than 6,000 kilometres in only 12 days using the Pegasus:Two to collect millions of points per second.
