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 and build accurate hydrographic software; specializing in applications for tidal data logging, tidal prediction, harmonic tidal analysis, surge prediction, datum conversion and mapping.

Our "easy-to-use" applications are in regular use worldwide; on-board vessels, at Port Authorities and in Hydrographic Offices. Customer List
