Optech's SHOALS Airborne Laser Bathymeters
are a well-proven tool, used for hundreds of surveys in a wide range
of applications. Based on the same principle as sonar, but using
light instead of sound, SHOALS gather shallow water, shoreline and
topographic (ground elevations) data simultaneously, integrating
land and water measurements in the same data set. Depth and position
measurements are accurate to IHO Order 1.
As well as
surveying water depths from the air, and thus avoiding the time and
access problems that bedevil other surveying methods, SHOALS can
identify underwater objects as small as 2x2x2 metres resting on the
ocean floor.
The SHOALS
system combines a powerful, probing laser radar (lidar) and
high-speed electronics on an airborne platform. Operating at
altitudes of 200-400 metres, with laser spot spacing variable
from 2x2 to 5x5 metres, SHOALS has a typical maximum depth
penetration of 40-50 m in clear water, 20-40 m in coastal
waters, and less than 20 m in more turbid inland waters.

Features
- High area coverage rate:
SHOALS scans at aircraft speeds, covering up to 70 km2/hr.
- High accuracy: meets IHO Order 1, position accuracy to within 1.5 m (depending on GPS).
- Fixed-width swaths, independent of water depth, unlike multibeam echo sounders.
- Compact and self-contained; installs into any medium-sized helicopter or fixed-wing aircraft.
- Real-time data display of depth soundings and position.
- Operator control:
Airborne operator can change pre-programmed survey parameters on the fly.
- Automated post-flight processing software with sophisticated manual editing tools.
Benefits
- Cost-effective in shallow water; cCollects dense data sets where acoustic surveying is least efficient.
- Maps extremely shallow water <5 m; no change in vertical accuracy or sounding density.
- Maps land and water in the same mission; simplifies coastal surveys by ensuring continuity through the shoreline in a single survey.
- Maps dangerous areas safely and thoroughly; airborne system immune to grounding hazards, shallows, shoal-infested waters, reefs, rocks, hidden subsurface objects or tidal flows.
- Flexible and rapid deployment; gets in and out quickly to take advantage of periodic and unpredictable access to areas cut off by harsh weather, poor water conditions, or features such as pack ice.
- Prompt damage assessment; maps quickly and thoroughly, generating a large volume of survey data that can be processed to produce damage assessments and dredging estimates, often the same day.
- Detects underwater objects; high-density coverage accurately targets objects as small as 2x2x2 m.
- Easy re-surveying; rapid deployment simplifies re-surveys of dynamic areas, to build up picture of processes over time.
