Our premier tidal product GeoTide is used by hydrographic offices, port authorities & shipping companies world-wide to create accurate tidal predictions.
By using GeoTide our customers reduce vessel waiting times and improve vessel throughput, directly benefiting port operations.
GeoTide converts your tide gauge data into harmonic constants, instantly creating accurate tables and graphs of tidal predictions.
For marine survey, GeoTide also calculates Tidal Levels, MSL, LAT, HAT, MLW etc. These contours are essential for safe Navigation, and as legal boundaries for access/fishing rights, ownership and fishery protection e.g. Marine Protected Areas (MPAs).
Using statistical analysis, GeoTide now calculates flood probability, its variation with height and its dependance upon rising sea level - for climate change, flood mitigation and flood-risk studies.
We also offer in-house services for Tidal Analysis & Prediction, and Expert Witness Legal Services on tidal matters.
GeoTide is used to determine the tidal constants for tidal stations on the River Thames and in the Thames Estuary by The Port of London Authority; these constants are then used by the UKHO as the official tidal constants in Admiralty Publications e.g. NP201.
