Target for ArcGIS is a geology mapping extension for Esri ArcGIS that simplifies 3D visualisation and analysis of drillhole and borehole geology data within ArcMap. Using Target for ArcGIS, you can visualise your geology data in 3D and conduct integrated analysis to enhance subsurface insight.
Subsurface Geology for ArcGIS
Geosoft has made it easier for earth explorers working within Esri ArcGIS. Explorers can visualise drillhole and borehole geology data and quickly integrate it with their exploration data without leaving their ArcGIS environment. Tight integration between Geosoft and Esri ArcGIS, with ArcEngine built-in to the Geosoft platform, ensures easy sharing of data, results and knowledge between both exploration and GIS environments.
With Target for ArcGIS, you can:
- Integrate borehole positions with geology, geochemistry or geophysics data through plan, profiles and section map views.
- Recreate sections and plans with a few mouse clicks.
- Automate legend generation, including lithology patterns.
- Present geological, geochemical, geophysical and geotechnical data in a single graphic display.
- Create up to 32 logs with data and graph type selections in each plot.
- Display your data in 3D with drill traces, surfaces and 3D models.
- Generate surface grids using robust methodology such as minimum curvature, kriging, and tinning.
- Enhance surface mapping with interval and exact level contouring.
- Generate a voxel (3D grid), incorporating the strike, dip and plunge from your geology.
- Display isosurfaces from your voxels.

A new digitization workflow for creating geological interpretations
A new streamlined workflow makes it easy to digitize geological interpretations on section maps using the native ArcGIS editing tools. You can save all your interpretations to a single Interpretations Geodatabase, making it easier to manage and to share geological models with colleagues.
Each Geodatabase can contain several sets of interpretations, stored as geological feature classes. 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.
Build wireframes from section interpretations
Target for ArcGIS now provides an easy-to-use wireframing interface that enables you to build 3D subsurface geological models by joining section interpretations stored in a Target for ArcGIS Interpretations Geodatabase.
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. Flat, conical or rounded ends can be used to close the open ends of a wireframed polygon feature. Polyline features will form open surfaces, and can be used to represent fault planes or contact surfaces.
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.
Easily collaborate on 3D modelling projects by sharing the interpretations (as a Geodatabase) or the wireframing results (as a Geosoft surface file or multipatch feature classes).
Note: ArcGIS 10 (SP5) or newer is required to use the wireframing workflow. Customers using ArcGIS 9.3.1 will be unable to use this feature.
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
Add 3D Vector files to Section and Plan Maps
You can now include 3D shapefiles and 3D DXF files while generating a section map in Target or Target for ArcGIS. This enables you to add 3D vector files (such as ore body wire frames and open pit outlines from mine planning packages) to section maps, plan maps and level plan slices. The imported 3D files appear in the correct location on your 2D section map. The 3D DXF file is clipped to the thickness of the section map (only the portion which exists inside the section is visible) while the entire 3D shapefile is projected onto the centre slice of the section.
