Shoreline Position

Shoreline Positions were manually digitized from orthophotos of the drone flights taken since 2018 at Dzita beach. The data is presented here in latitudes and longitudes. To see the shoreline positions per year, select the year from the filter icon on the figure and submit.

Waterline points

Period of record
May 2018 – Oct 2024
Surveys
56
Beach section
2,473 m alongshore

Repeated waterline traces of the same beach section, surveyed on the projected Ghana National Grid in metres. Under that grid's identified orientation the sea lies south, so landward and seaward directions are stated accordingly; survey positional accuracy has not been quantified, so change rates should be treated as indicative.
