ManaMar

I started this project because diving had no proper cartography — no tools bringing relevant information to divers where it matters most: underwater.

Now it's the world's first collaborative underwater map app.

Collecting bathymetric data — Costa Brava.
The Storyline

The data already existed.
Nobody could use it.

01
The gap

A point cloud isn't a map.

Raw bathymetric data is millions of scattered depth points — unreadable without a GIS pipeline built to translate it.

02
The first products

Something tangible that divers can take underwater.

I turned the same survey data into 2D prints and 3D-printed models — formats built to work both on the surface and below it.

03
What it became

From a personal pipeline to a platform.

A collaborative underwater map app, built to scale worldwide — and to host B2B services for the dive industry.

The App

All the maps, now on your pocket

ManaMar's own product: a collaborative underwater map built by divers, for divers — offline-ready, with live depth contours pulled from the same pipeline.
