About this Release
Target 8.0 is a scheduled software upgrade available to all maintained customers. This release includes significant advancements to help you visualize your 3D subsurface data.
New digitizing tools enable you to combine your expert knowledge with real data to draw accurate geological interpretations on section maps. An intuitive wireframing workflow makes it easy to build 3D subsurface geological models by joining 2D interpretation sections to create 3D wireframe bodies. Share your interpretations as geostring files and wireframing results as geosurface files.
Geosoft Seeker is faster and more responsive, featuring a new simplified interface for searching and downloading data.
How to update
Online installs for each product are available through the Check for updates option within the software and from the download link at the top of this page. If you require the upgrade on a DVD, you can request one here.
Target 8.0 runs on Windows 8 (32 and 64 bit), Windows 7 (recommended) (32 and 64 bit) , Windows XP SP3 (32 bit), or Windows Vista (32 and 64 bit) operating systems. See detailed System Requirements
Create multiple isosurfaces from voxel
You can now create up to 12 isosurfaces from a voxel automatically using a linear or log distribution. This enables you to automatically create 3D contours from a voxel. To make it easy to view the results, all the isosurface layers are displayed with 50% transparency, except the inner-most surface, which is opaque. Intelligent defaults (5 isosurfaces, linear distribution, good colour contrast for surfaces) are provided with the option of manually customizing the isosurface values and colour. The isosurface results are written to a single geosurface file, which you can easily share with others.
Export a Geosoft database to an Esri File Geodatabase
Export magnetic, gravity or other geophysical datasets directly from a Geosoft database to an Esri File Geodatabase. Geophysical survey data can be exported either as a point feature class or a line feature class.
Geostring file format
Geosoft geostring is a new file format (*.geosoft_string) used to store geological interpretations that are digitized on section and plan maps. A single geostring file stores all the geological interpretations for a drillhole project, which can include a combination of several polygon and polyline features (which represent different rock types, alteration or mineralization zones and fault or contact surfaces). Keeping all of your interpretations in a geostring file helps you keep your project information up-to-date and share it with others.
Geosurface file format
Geosoft geosurfaces are 3D vector files that store the results of wireframing or isosurface creation. Closed surfaces are the result of wireframing polygon interpretations and open surfaces result from wireframing polyline interpretations. Several closed and open surfaces from a wireframing session can be saved to a single geosurface file, just as several isosurfaces extracted from the same voxel can be saved to a single geosurface file. This single file solution (one geosurface per wireframing project or voxel) makes it easy to manage the wireframe or isosurface results and to share your work with others.
Interactively clip a voxel to create an isosurface
Visually clip a voxel to create an isosurface from the voxel. This new workflow allows you to interactively clip a voxel to determine the surface value for the isosurface. The isosurface is then automatically created at that specified value and displayed using the same colour as the voxel cells at that value. When the isosurface is created, the isosurface results (not just a map group as was the case previously) are saved to a geosurface file, which you can easily share with others. A geosurface file is able to hold multiple isosurface values in the same file, so you can extract several isosurfaces from the same voxel and append them all to a single geosurface file.
Project Explorer pane improvement
It is now easier to manage files from the Project Explorer window within Oasis montaj or Target. You can now select multiple files and permanently delete these files from your hard drive. You also have the option of deleting any auxiliary files that are associated with the files you have selected.
Watch the new Seeker videoSeeker is now more responsive and faster, featuring a simplified interface for searching and downloading datasets. This new interface makes it easier to find and download data with your Geosoft application or plug-in.
3DV file format
You can now export a 3D View as a 3DV file (*.geosoft_3dv). This creates a "3D package" that contains the entire 3D model and the all the associated datasets for the 3D View. This enables you to easily share 3D Views with collegues or to quickly move 3D maps and all their associated files from one folder or drive to another. All the display settings (transparency, colours, clipping) are saved to the 3DV file. When you import a 3DV file, it displays exactly as the 3D model appeared on export and the data files are unpacked to the project folder. 3DV files can also be cataloged in DAP.
A new digitization workflow for creating geological interpretations
A new streamlined workflow makes it easy to digitize geological interpretations on section and plan maps. Polygon features can be used to represent individual rock units, alteration or mineralization zones, while polyline features can be used to draw faults or contact surfaces.
A single geostring file can contain a number of interpretations stored as geological features. Using a single geostring file to store all the interpretations for a drillhole project makes it easy to manage your interpretations and share them with others.

Improved snapping for new digitization workflow
When digitizing, you can now snap to the true X, Y, Z drillhole data locations, or to the points that are projected on the section plane. This provides you with more flexibility and control when digitizing interpretations, which leads to more realistic and accurate interpretations.Watch the video
Build wireframes from section interpretations
Geosoft provides an easy-to-use wireframing interface that enables you to build 3D subsurface geological models by joining section and plan map interpretations stored in Geosoft string files. Simply click on the features you want to include and a wireframe model is created from the shapes. Polygon features form closed surfaces or bodies and polyline features create open surfaces. Flat, conical or rounded ends can be used to close the open ends of a wireframed polygon feature.
After saving the wireframe to a Geosoft surface (geosurface) file, the total surface area is reported for open surfaces and total volume is reported for closed bodies. Closed geosurfaces can be used in voxel math expressions to clip voxels or to create constraints to use in inversions. Collaborate on 3D modelling projects by sharing the interpretations as Geosoft string files or the wireframing results as Geosoft geosurface files.Watch the video
Voxel math expressions using closed 3D geosurfaces
You can now use closed 3D surfaces from wireframing as variables in voxel math expressions, enabling you to clip voxels to the inner or outer edges of a 3D surface.
There are a number of ways you can use this functionality. For example, you can clip voxels to a closed surface to calculate an average grade within a specific rock unit or you can assign a constant value to the voxel cells inside or outside the closed surface, which makes it much easier to create constraints for VOXI.Watch the video
Added the Popular Visualization Datum (PVD) used by Bing Maps
Added support for the Popular Visualization Datum (PVD) which ensures that Bing Maps image layers reproject correctly into non-geocentric datum based maps.
DappleSearch data indexing service
This is an upgrade to the web service that finds and validates online data sources through publicly available servers. It increases the number of online services, making it easier for customers using the Seeker or Flamingo interfaces to search for data.
