Local authorities are being given a helping hand in maintaining gullies and alleviating the risk of flood due to blockages by using Yotta DCL’s precision edge digital inventory surveying service. Using groundbreaking Nano software for extracting gulley asset information from high definition photography, Yotta DCLs service helps highways departments gain a clear and accurate view of all gullies enabling them to target problems. 
 
By importing the data into a Geographic Information System (GIS) highways engineers can construct models showing problem gullies, their precise location and flooding potential. This allows them to assign maintenance to those in need of urgent attention, leaving the rest to planned routine maintenance according to their condition.
 
The additional benefit of digital asset collection for gulley management programmes is cost reduction. By being able to pro-actively maintain gullies local authorities will reduce the overall cost of maintenance and repair. For example, where gullies throughout an authority are cleaned twice a year in their entirety, highways departments are now able to reduce this number and therefore slash costs.
 
For the digital survey Yotta DCL uses a specially designed and developed vehicle equipped with six high-resolution cameras that provide a full 360-degree street-level view of the highway. The cameras take a photograph every two metres as the vehicle drives along, with the precise position of the vehicle recorded by a high end GPS Inertial tracking system. These photographs are processed, evaluated and analysed pixel-by-pixel by the Nano software to give a highly accurate view of each inventory item captured on the journey.
