Geochemistry for ArcGIS 2.1 is a scheduled software upgrade available to all 2.0 maintained customers. Geochemistry for ArcGIS 2.1 includes important advancements that improve access to data and information, make duplicate sampling identification more efficient, and expand geochemical visualisation and analysis capabilities. Enhanced software usability will help you be more productive when working with geochemical data in ArcGIS.

System Requirements

Geochemistry for ArcGIS 2.1 runs on Windows XP Service Pack 3 32-bit (minimum), Windows Vista Business (32-bit and 64-bit) and Windows 7 [(32-bit and 64-bit) - recommended] operating systems. See detailed System Requirements

New Capabilities


Gridding enhancements

IDW griddingclick to enlarge   Creates a grid from point data using an Inverse Distance Weighting (IDW) algorithm. IDW gridding is primarily used to interpolate geochemistry data.

3D Visualization

Zoom to extents of visible groups You can now toggle the auto-zoom behaviour off or on, providing you with additional control over how and when the viewing extents change in 3D.
Improved 3D DXF export Updated the export of 3D DXF files to incorporate 3D Face objects as well as polyface mesh objects in our DXF exports. Other software packages (including ESRI ArcScene, GEMCOM, Datamine, Maxwell, Micromine) which only support the 3D Face objects are now able to import Geosoft created DXF files.
Improved 3D PDF export Upgraded our 3D PDF exports to take advantage of new compression methods. 3D PDF exports now create dramatically (up to 10 times!) smaller 3D PDF files which are easier to share.
3D view orientation buttonsclick to enlarge New buttons in the 3D Viewer enable you to quickly change the viewing angle to a pre-defined view (North, South, East, West, Top and Bottom) or to a user-defined viewing angle, making it easier to view a 3D model from any angle. 
3D Snapshots Snapshots of 3D views may now be created, saved and recalled, enabling you to easily store and retrieve specific viewpoints for your 3D models.
Visual clipping of all groups in 3D viewclick to enlarge You can now use the 3D view clipping tools to clip all 3D object types, including: drillholes, symbols, grids and surfaces. You now have the ability to select and visually clip multiple 3D objects at one time. This saves time and provides more flexibility when displaying a few or all of the objects in a 3D view.

Help System

Improved Application Helpclick to enlarge
  • Help topics are now organized around workflows associated with the specific Geosoft Data Processing Sequence steps (Prepare, Import, Edit, Process, etc.) and conveniently display topics by information type (Concept, Procedure, and Reference).
  • The Help system launches as a browser window in the new and improved WebHelp format, featuring appealing formatting and visuals consistent with our Geosoft branding.
  • Breadcrumbs added to the topic to assist in easy navigation and Help topics and specific search queries can now be tagged as Favourites.
  • Updated help topics can now be sent as part of software resource updates, ensuring you always have the latest help content.

ArcGIS 10 Support

Layer Packger saves to version 10 files With this release users will now have the ability to create and save LYR packages in version 10 format. LYR packages encapsulate both the layer properties and the dataset referenced by a layer. The symbology, labeling, table properties and the data are all saved and shared between other current ArcGIS Desktop 10 and Oasis montaj users in one easily shareable package.

Enhancements and Maintenance Fixes

IS8571 Added ability to add clipping to all 3D groups and planes and clip several groups at once
