National Trust – Cemlyn
Cemlyn is in an area of outstanding natural beauty on the north coast of Anglesey, North Wales.
This was a project carried out last summer (2015). We were commissioned by the national Trust to map 200 hectares of land belonging to them, that in the future may be suseptable to flooding in the event of global sea level rise. The lower parts are just above see level presently. The area is also next to a proposed new nuclear facility build.
The area falls within a restricted no fly zone (Wylfa Nuclear Power Station) , we worked with the Civil Aviation Authority and Wyklfa security staff in order to safely carry out the survey. We also liased with Horizon, who are building Wylfa Newydd next to this site. There were many safety considerations we had to take into account in order to legally carry out this survey.
The survey itself consisted of over 2000 24MP photos, which produced a point cloud in excess of 2 billion points. Ground control point, over 100, were used to accurately create and position the digital elevation model according to british national grid. The control points were measured using a state of the art netwrtked GPS rover.
