Coastal Topographic Surveys

Coastal Topographic Surveys are height transects that form part of the Anglian Coastal Monitoring Programme. A surveyor using a GNSS (Global Navigation Satellite System) staff will make observations of elevation and usually substrate type at recorded coordinates. This is usually carried out along a fixed transect line, but can be along a grid or, when the staff is mounted to an ATV (All terrain vehicle), a high volume of ‘spot height’ measurements through the survey area. The outputs of this survey are the easting and northing coordinates of each location where a measurement was taken and the elevation in metres above Ordnance Datum (Newlyn). The transect survey data will also contain a chainage position of where along the transects the measurement was taken and a two letter substrate code.
