Software review: Next generation technology enhances data access and insight into the subsurface

by Carmela Burns technology

To help focus their exploration, earth scientists and exploration companies need to fully leverage the value of all available data. Many Government Geological Surveys have deployed Geographic Information Systems (GIS) and are using ESRI’s GIS platform to publish their geological data. Geophysical data released by Government Surveys is typically published in exploration formats like Geosoft format grd and gdb. The end result is that geoscientists are now working with and integrating both GIS and exploration datasets as part of their daily projects.

The latest software developments enable exploration teams to effectively utilize GIS data and tools, as an integrated part of their workflow. Continuing advances in Globe Explorer and three dimensional capabilities provide powerful new ways to find, view and integrate earth data and exploration information to make the best use of all the data you have available, and to interpret the data for maximum insight.

Single Environment for Working with GIS and Exploration Data

The latest release of Geosoft’s earth mapping software now features ESRI’s ArcEngine technology built-in. Designed to create a seamless connection between the geosciences and GIS for professional earth explorers, Geosoft now enables geoscientists to use ESRI tools to natively display Arc .mxd and .lyr files, without leaving the Geosoft environment. ArcGIS and Geosoft users can share their files seamlessly and spend more time collaborating in an increasingly integrated environment.

"We are excited that the solutions offered by Geosoft and ESRI are being so well received," says Geoff Wade, Natural Resource Industries Leader for ESRI. "Geosoft has done an excellent job of improving workflows and enhancing integration with ESRI software, to deliver value to the earth sciences community."

Additional features of the ESRI integration include cursor tracking and dynamic linking between MXDs and Geosoft Maps, and the ability to save MXD files as Geosoft Maps, or Geosoft Maps as MXD files. To make data sharing efficient, users can drag and drop layers between MXDs and Geosoft Map groups, and the redesigned Coordinate System tool supports ESRI projection files (PRJ).

Access More Data with Globe Explorer

Geosoft has added the Dapple globe explorer as a core component of its software platform, enabling powerful access to a larger data universe.  Geoscientists can find, view and extracting data from a variety of data servers, including public DAP servers, WMS servers, ArcIMS servers, Tile Servers, and in-house data. They can search for data, and integrate it into their projects without leaving the Geosoft environment.

Along with enhanced Area-of-Interest searches using the globe explorer, new capabilities include a WEB spatial data search engine for locating available public data, and a text search to narrow searches to topics of interest.

Maximize Insight with Powerful 3D Views

Geosoft has expanded and simplified its three dimensional capabilities, within its own software (Oasis montaj and Target) and also within its exploration geology extension software for ESRI’s ArcGIS (Target for ArcGIS).

With the latest advances, Geosoft enables powerful integration and 3D views of subsurface geology, such as: fence diagrams, 3D geology voxels, and the automatic creation of 3D geological surfaces. These 3D capabilities enable geoscientists to integrate their data and enhance their view of the subsurface for more accurate results, greater insight and better decision-making.

3D Geology Surfaces.

Create an elevation grid to represent the top or bottom surface of a lithology unit based on a lithology channel in a Geosoft Drillhole database.

You can create a geology surface grid from any geologic attribute, such as rock type, alteration, or mineralization. You can also extract a profile of the 3D geology surface grid into a section view without digitizing.

3D Lithology Models From Drillhole Data

A geology 3D model can be created from any geologic attribute, such as rock type, alteration, or mineralization, enabling you to display only the rock unit of interest.

Once the 3D model is created, each individual rock unit in the model may be toggled on or off to be viewed separately or together.

Professional Fence Diagrams

Fence diagrams are useful when comparing down hole geology from a limited number of holes. The ability to create fence diagrams provides geologists with an additional mapping option for displaying and viewing drillhole data. There are many down hole data display options, including automatic creation of geology polygons between holes.
