What's New

Three big upgrades, live now in BathyMaps Premium.

Just Released · 3D

3D is here — see the same ground in 2D and 3D.

Our biggest release yet. Flick the new 3D toggle and the bathymetry rises into living terrain — every ledge, pinnacle, lump and bump. Read your contours and depths in flat 2D, then tilt into full 3D to see exactly how the structure stacks up.

BATHYMETRY · 2D ⇄ 3D · UP TO 20×

The same reef shown side by side in 2D and 3D

High-res satellite imagery basemap in 2D

New · Imagery

High-res satellite imagery, draped over the reef.

A brand-new IMAGERY basemap brings crystal-clear satellite detail to the map — every sand patch, bommie and coral edge. Switch it into 3D and the imagery wraps straight over the terrain. It looks unreal.

OceanCast

Live ocean data, right where you fish.

OceanCast layers bring real-time and forecast sea surface temperature, sea surface height, chlorophyll and total currents — integrating ocean, tidal and wind currents for a complete picture of conditions before you head out.

The Maps

Mapping built around the way recreational fishermen actually plan.

BathyMaps is a bathymetry-based mapping company that aims to provide fishermen-focused maps. Our maps use the most recent and highest resolution bathymetry data available. We enhance our bathymetry data to highlight subtle depth changes for optimal identification of seabed structure. We understand that no single map can fit everyone's needs, so we have developed multiple maps to accomodate different fishing strategies.
