Creating the map
The Blue Lagoon map has taken over a year to produce. It was created by taking hundreds of measurements and keying these into the Site Recorder SE software from 3H Consulting. The software ensures that all the measurements are consistent with each other, and generates co-ordinates that can be plotted on a map. These survey skills were learnt on the NAS part one course.
All measurements are recorded to the nearest 10cm, and we are aiming for a positional error of less than 1m. Since the water level varies, our vertical datum is defined as the metal ring in the concrete block to the left of the jetty. Three external survey points were taken, using latitude/longitude values from Google Maps™.
