Accurate hydrography is important.

Not only for the safety of navigation, but also for the design of sea defences, tidal power schemes, in flood risk analysis, in vessel manoeuvring, in vessel passage planning, and in defining a vertical datum.

We design, build and supply accurate hydrographic systems; specializing in tidal data logging, tidal prediction, harmonic tidal analysis, surge prediction, and electronic charting.

Our "easy-to-use" applications are in action on-board vessels at sea, and on land at port authorities and in hydrographic offices, worldwide. Customer List

We also provide in-house hydrographic and tidal services. More..
