SEQUENCE OF WORK

Survey work was conducted across the village

Point cloud data obtained from a high definition laser scanner was used within a CAD software package.

A 3D computer model of a proposed path and viewing area over the bay was merged with the terrain model.

Potential uses of digital terrain models:

Here an example is shown of how two 45m high pylons would impact the landscape.

Digital Terrain model of rural village

Background:

A collaboration with Advanced Simulation Technologies Ltd. A controlled survey with a High Density Scanner was used to capture 3D data of a hill, village and coast. The hill survey was conducted so that it can be monitored for movement over time.

A digital terrain model was produced which provides accurate spatial data of the whole village.

A 3D designed proposal for access to the coast was incorporated into the terrain model. The model can provide accurate dimensions and be used as a visualisation tool.

The data captured is obtained with a rotating laser and to millimeter precision. Therefore the models represent a real life simulation of the environment. The accuracy of the spatial data allows for volume, distance and area measurements of much greater reliability than would be gained from OS maps. Analysis with regards to flood risk, coastal erosion, overlooking and shadow analysis are just some examples of how this technology can be used.
