GDM Suite: a software suite allowing to model, represent and visualize geoscientific data and geological model in 3D

The GDM Suite has been developed by the BRGM to manage, display and model geological data, in various fields: geology, town and country planning, water resources, pollutions, natural hazards, mineral resources, geotechnique, geothermal energy...

GDM Software Suite offers tools for geosciences and land planning professionals to model, exploit and make full use of geoscientific data and geological models: 

  • 3D geological model building from geological data (boreholes, geological maps, geological cross-sections, interpreted geophysical profiles…) 
  • Geostatistical analysis and interpolation of variables (top of a formation, water table level, pollutant concentration…) 
  • Data consistency control 
  • Representation of data and models with well logs, maps, cross-sections and 3D views either with GDM, ArcGIS or on the Web 

The GDM Suite includes the following items: 

  • GDM Standard 
  • GDM MultiLayer 
  • GDM Viewer 
  • GDM ArcGIS 
  • GDM Web Services

GDM Standard: Data representation and modelling

GDM Standard includes all the standard features of the BRGM's GDM Suite.

GDM Standard includes all the standard features of the GDM Suite. 

Description of the GDM Standard 

GDM Standard is used to display and model geological data with X, Y and Z coordinates: 

  • of all types: wells or boreholes, punctual data, geological boundaries, faults, samples, grids 
  • in any form: geological codes, descriptive texts, analysis results, diagraphs, images. 

GDM Standard will directly handle data in Text (CSV) / Excel / Access / Oracle / SQL Server / PostgreSQL. 

GDM Standard produces high-quality graphs: 

  • 1D: multi-column sampling logs 
  • 2D: maps, vertical cross-sections (along straight lines or broken lines) with several graphic layers 
  • 3D: all GDM objects that can be represented in 3D, with system back-up of the different views 
  • "inter-view" system for parallel location of data in the 1D, 2D and 3D views 
  • interactive graphs to consult, from the graph,  the information  on a given data point, sample, grid node, etc. 
  • export of 1D and 2D in vector mode for incorporation into your documents  with no loss of resolution 
  • export of 3D views in raster mode 
  • mass export of drill hole logs  and serial cross-sections 
  • Your customers can view 1D, 2D and 3D documents in their original format using the free GDM Viewer 

GDM Standard enables geological modelling and interpolation of a wide array of parameters: 

  • automatically (interpolation)  
    • using geostatistical or other interpolation methods 
    • with faults and boundaries 
    • by computing composites along core samples (mineralised seam, cross-section of polluted ground, facies proportion, etc.) 
  • manually by digitisation onto maps and cross-sections 

Results are displayed as isovalue curves, cross-sections or possible calculated volumes. 

Fields of application of GDM Standard 

GDM Standard Edition has applications in different fields of the geosciences: 

  • water resource management, 
  • geotechnics, design of tunnels, dams or underground storage sites, 
  • Land and urban planning, 
  • mineral resource exploration and extraction, 
  • diagnoses of underground pollution, 
  • natural risks: underground cavities, sinkholes, etc. 
  • geothermal energy.

GDM MultiLayer: Three-dimensional geological modelling

GDM MultiLayer is an extension to GDM Standard that automates the construction of multilayer geological models. This extension is part of the BRGM's GDM Suite.

Building geological models 

MultiLayer is a GDM extension to rapidly build up multilayer 3D geological models, with considerable productivity gains. 

MultiLayer offers easy processing of geological data stored in a GDM project with automated management of the geological modelling workflow. 

After defining the stratigraphic column of the geological formations to be modelled, a set of tools for data consistency analysis and cross-checking are available to verify, correct and interpret the data. 

A wizard then guides you through the model-building process. All the parameters used in building up the model can be saved and reused. 

The model is easy to use thanks to the automated production of maps, cross-sections and 3D views that can be exported to different formats. 

Fields of application 

  • Mineral resource exploration and extraction, 
  • Water resource management, 
  • Geotechnics and civil engineering 
  • Designing tunnels, dams or underground storage sites, 
  • Land and urban planning, 
  • Geothermal energy. 

Licencing conditions / prices 

To build up multilayer 3D geological models: 

Prerequisite : A GDM Licence is required 

Window application : 

  • Single-user or network licence 
  • Academic licences

GDM Viewer: Visualisation of data and geological models

GDM Viewer is a free tool to display and query data, models and graphic documents stored in a "GDM project". It is also available for your customers to visualise the models you built for them.

The viewer provides all the GDM Standard query and search functions for 1D, 2D and 3D graphs. 

Graphs can be printed or exported in different file formats (WMF, JPEG, etc.). 

The viewer can be supplied to your clients so they can consult the models you built for them even if they do not have a GDM software licence.

GDM ArcGIS: an extension of GDM Suite for ArcGIS

GDM ArcGIS is an ArcGIS extension enabling ArcGIS users to display GDM geological data and models and use GDM geostatistical methods.

GDM ArcGIS allows ArcGIS users to: 

  • display (from ArcMAP) GDM documents (GDM Multilayer geological models, drill hole logs, maps, sections, 3D documents) developed under GDM projects. This allows the user to benefit simultaneously of the strength of ArcMap for 2D visualization and of the strength of GDM to display drill hole logs, cross sections anf 3D views from a geological model 
  • use the GDM geostatistical analysis tools (gistogram, variogram, geostatistical interpolation of points or grids). 

GDM ArcGIS r applications can be found in the same fields as GDM: 

  • water resource management, 
  • geotechnics, design of tunnels, dams or underground storage sites, 
  • land and urban planning, 
  • mineral resource exploration and extraction, 
  • diagnoses of underground pollution, 
  • natural risks: underground cavities, sinkholes, etc. 
  • geothermal energy. 
  • geosciences in general

GDM Web Services: Representation of geological data and models on the Web

GDM Web Services is a set of "web" components designed to incorporate GDM functions into an on-line GIS on your web site.

GDM Web Services is a set of customisable web services such as online displays of logs, maps or sections. 

These services can be integrated in your website to provide your geological information to agents, clients or partners. 

The BRGM also offers full hosting and data management services through totally secure intranets or internet.
