GEOCARTA — high-resolution subsurface imaging through geophysical methods

The soil holds a story.

Beneath every parcel, a variability the eye cannot see.

A scientific acquisition.

ARP® technology measures the subsurface continuously, without ever disturbing it.

Current reveals matter.

Electrical pulses cross the soil horizons and expose their structure.

Measurement becomes map.

Thousands of georeferenced points, interpolated into high-resolution mapping.

Indicators you can act on.

Resistivity, texture, depth, available water: soil translated into agronomic data.

The subsurface in volume.

From topsoil to bedrock, read in three dimensions.

25 years reading the subsurface.

Geophysical expertise serving agriculture, land development, viticulture, environmental studies and archaeology.

Introduction

We make the subsurface legible.

GEOCARTA is an applied geophysics consultancy. We work in France and internationally. We map the subsurface from the surface — no boreholes, no destruction — turning uncertain ground into information you can act on.

What sets us apart fits in one sentence: we design our own instruments, build our own software and run our own servers. From field measurement to delivered map, no step is outsourced. That is what lets us fit the method to the problem rather than the reverse.

Our application domains

Five sectors, one subsurface.

The questions change, the physics does not. For each sector: a problem, an investigation strategy, deliverables that fit.

Applications

Our know-how

From the question to the decision.

A geophysical survey is only worth what it changes. Our approach always follows the same path — and it starts with your problem, never with an instrument.

  1. 01

    The question

    Cavity, buried tank, utility network, soil depth, heterogeneity, archaeological remains. The need determines everything that follows.

  2. 02

    Geophysical method

    We select — and combine — the methods suited to the context, the objectives and the constraints of the site.

  3. 03

    Acquisition

    Continuous, georeferenced measurements taken from the surface, with no boreholes and no destruction.

  4. 04

    Mapping

    Processing, interpretation and high-resolution mapping of the variations in the subsurface.

  5. 05

    Decision support

    Deliverables you can act on directly: borehole siting, zoning, intervention planning.

Our geophysical methods

Four methods. One strategy per project.

The method is not chosen in advance. It is fitted to the context, the objectives and the constraints of the site — and more often than not, several are combined.

Geophysical methods

The multi-method approach

No single method answers every question. Crossing them removes the ambiguity: what resistivity suggests, radar confirms; what magnetometry detects, electromagnetics characterises. This is our principal differentiator.

Our digital solutions

Your results stay alive.

We build our own platforms. A map is not delivered as a PDF and then forgotten: it stays viewable, shareable and usable by your teams.
