Where light ends, sound begins.

Seabed intelligence and marine solutions.

What we do

We measure the sea, then we make it visible.

The sea holds an entire world that cannot be seen from the shore. LUJJAH Tech turns scientific marine data into experiences people can actually see, hold, and use.

3D coastal and bathymetric models

Your coast. Your reef.Your story.

Some things are better held than described.

Survey data and underwater imaging become a detailed physical model that brings the underwater landscape into the room. Set on a reception desk or a conference table, it shows the relationship between coastline, seabed, reef and depth without a single line of explanation.

  • Survey, process, visualise, experience
  • Resorts, hotels and coastal developments
  • Visitor centres and exhibition spaces
  • Government, research and education

Underwater Reveal

Reveal whatlies beneath.

Your phone becomes your eyes underwater.

LUJJAH Tech turns survey data and underwater imaging into an augmented reality experience. A visitor points their phone at a banner, and the camera shows what the sea is hiding: the reef, the seabed, the depth beneath their feet. No mask. No boat. No certification. Just a phone and a shoreline.

  • Coral reefs and reef formations
  • Seabed features and coastal landscapes
  • Bathymetry and underwater terrain
  • Water depth and depth variation

LIMA

The gateto the sea.

Every beach, dive site and sea condition in one app.

LIMA brings beaches, offshore environments, diving locations, marine activities and sea conditions into one place. Instead of searching across scattered sources for information about the sea, everything sits in one platform, before the journey, during it, and at the destination.

  • Discover the sea, its reefs, wrecks and sites
  • Know before you go, with weather and sea state
  • Get there, online or offline
  • Bathymetry and depth where available

Hydrography and Environmental Monitoring

One operation.Many answers.

LUJJAH Tech measures the marine and coastal environment to understand its condition, its character and how it changes.

Five measured layers lifted apart above a coral reef, each labelled: bathymetry, backscatter, side scan, water quality and seabed classification
Visualisation

Water quality

  • Temperature and salinity
  • Water clarity and turbidity
  • Dissolved oxygen and pH
  • Trends over time

Hydrography

  • Water depth and bathymetry
  • Seabed shape and terrain
  • Currents, tides and water movement
  • Waves and water-level variation
  • Underwater features and hazards
  • Sediment movement between surveys

Marine and coastal change

  • Coral reefs and marine habitats
  • Coastal environments
  • Underwater change over time

LUJJAH Tech combines field measurements, hydrographic surveys, underwater observations and environmental data to create a clear understanding of marine environments and how they change over time.
