Fathom
Aerial topo-bathy coastal mapping solution.
Coastal mapping with an edge
The world’s fastest, most intuitive aerial topo-bathy coastal mapping solution. Featuring real-time QC and fast post-processing.
Fathom addresses common challenges around the cost and technical complexity of topo-bathymetric surveys by drawing on Optech’s innovations in sensor miniaturisation, real-time data processing, and streamlined production workflows.
It was developed in response to feedback from government and engineering organisations, which highlighted a lack of critical geospatial data needed to manage resources and infrastructure across land, the intertidal zone, and the seafloor.
FATHOM – Datasheet
A Comprehensive Solution
1 – Topographic Lidar

Fathom for Land Surveyors
Use for land applications and complement your existing operations with marine capability.
Meets the established standards for topographic density, precision and accuracy.
Fathom for Hydrographers
Map the gap between land and water. Complement acoustic surveys by delivering detailed data over the coast. Meets IHO Special Order standard and delivers data 45x more productively in the intertidal zone. Access remote and shallow project areas, safely and at a fast coverage rate of 50km2/hr.
Fathom for Photogrammetrists
From a single instrument deliver crisp imagery for orthomosaics, 3D models, colourised point clouds and vectors.
Complement imagery projects with critical 3D information for accurate hydrologic models.
FREQUENTLY ASKED QUESTIONS
What makes Fathom different from other lidar systems?
Fathom stands out for its real-time data processing, compact design, and ability to map both land and water seamlessly. It’s optimised for smaller aircraft and requires only a two-person crew, making it more cost-effective and accessible than traditional systems.
Can Fathom be used in Australian coastal environments?
Yes, Fathom is well-suited for Australia’s diverse coastal conditions. It performs reliably in varying water clarity and depth, and meets IHO Special Order standards for hydrographic surveys, making it ideal for mapping reefs, estuaries, and intertidal zones.
What kind of data does Fathom produce?
Fathom generates colourised point clouds, orthomosaics, 3D terrain models, and multispectral imagery. This data supports applications in hydrologic modelling, shoreline digitisation, and infrastructure planning.
How fast can Fathom cover an area?
Fathom can map up to 225 km² per hour for topographic surveys and up to 50 km² per hour in coastal and shallow water environments. This high productivity makes it ideal for large-scale projects.
What aircraft can carry the Fathom system?
Fathom is designed for use with smaller aircraft, including UAVs and light planes. Its compact, gyro-stabilised design reduces flight costs and simplifies installation.
