Marine survey suite · by Bozkurt

Know exactly how much is above the design, and how much is missing.

BATHYON turns a survey into the numbers and drawings a marine works job is paid on: volumes split at the design surface, difference charts a client can sign, and cross-sections that frame themselves on the structure.

quick section · volume · split at the design surface

A quick section with volume on: the bed against the design, the material above it and the shortfall below it measured separately.

−02 m · what it does

Four answers a marine works job actually needs.

Not a list of tools — the questions a dredging or reclamation contract asks every week, and how the suite answers each one.

How much material, and on which side of the design?

Draw a section or a polygon and the volume is split where it matters: what stands above the design surface and what is still missing below it, as two separate figures rather than one net number that hides both.

Volume inside a polygon, between any two surfaces or against a design
Above and below the design reported separately, with the areas shaded on the section
As-built beyond the design footprint counted or excluded — your call, stated on the sheet
PDF volume report with the zones listed

Is the bed inside tolerance — and where is it not?

A difference chart against the design or a previous survey, coloured by your own table, so over-dredge and shortfall read at a glance and the same sheet goes to the client.

Any surface against any reference, or two surveys against each other
Dredge-tolerance view with your ± window painted white
Colour tables you author and save, applied live — one table, no re-loading
Contours over the colours, ink chosen to stay readable on every band

Can the sections be on the desk before the concrete?

Chainage along the route or a line drawn anywhere, cut through every loaded surface at once. Each sheet frames itself on its own design plus a margin, so the structure fills the page instead of sitting in a corner of a fixed box.

Design, tolerance envelope and as-built on one sheet
Automatic frame per section, or a fixed window when you want them identical
Title block, section table, geodetic notes, PDF and CSV
The quick profile cuts everything ticked, live, while you move the line

Are the soundings clean before anything is built on them?

Spikes are removed where they still are — in the raw swath, not after gridding, where a bad ping has already spread into the surface and the volume.

Reads the raw acquisition logs directly
Slice view: step along the line and reject by eye, in the density
Automatic filters with the cut always drawn before it is applied
Clean XYZ out, or straight into a grid model

−06 m · how it is arranged

Three programs, one project folder.

They read the same folder and hand work to each other, so a line cleaned in the morning is in the volume report that afternoon — no export step in between.

CHARTthe working surface

Surfaces, designs and differences on one chart — with the edit tools, colour tables, contours, 3D view, quick profile, cross-section sheets and the volume calculation.

CLEANraw multibeam

Slice-view spike removal on the raw logs, automatic filters, clean points out.

Position in over serial, UDP or TCP; ENC and free charts; AIS with CPA/TCPA; survey runlines with cross-track error; everything logged.

−10 m · interoperability

It fits between the systems you already run.

Files arrive as they were written and leave in the form the next desk expects — no intermediate export, no “please send it as XYZ”.

Reads

.dtm .grd: Grid models from the common acquisition and processing packages
.3dm: TMC design surfaces, triangles kept verbatim
.xml: LandXML TIN from Civil 3D and VOSS — read as a stream, so 80 MB exports open
.dxf .dwg: Design surfaces, chart overlays, 3D-line wireframes
.col: Colour tables, applied exactly as authored
.rte: Routes, with arcs reconstructed
.xyz .pts .csv: Point data, column order detected

−14 m · how it is built

Measured, not claimed.

Survey software earns trust the way a survey does: by being checked against something that did not produce it.

Checked by the software that will receive it

Every design written here is opened in the field package and read by its own check routine. Its error list is the score — not our own counters, which were wrong the one time we trusted them.

Nothing is invented

Triangles read from a file are written back exactly as they came. No welding of near vertices, no filling of excluded regions, no phantom faces where the design has a gap on purpose.

The 0.01 mm rule

On a design surface no repair may reach further than a hundredth of a millimetre. Three attempts to be cleverer than that made the errors worse, and all three were rolled back.

Light does not survive the water column. Sound does — and so does a measurement you can reproduce.

−18 m · get in touch

Written on the job, not for a brochure.

BATHYON is built and used by a working hydrographic surveyor on live dredging and marine-works quality control in Dubai. Every feature in it exists because a survey needed it that week: a groyne that had to be sectioned before the concrete, a volume a client would sign, a design a contractor's software had quietly broken.
