Target for ArcGIS 2.1.0 Release Notes

May 1, 2006

Target for ArcGIS 2.1.0 is a major release that includes:

The 3D Tool enables you to view boreholes in full 3-dimensional perspective, with the ability to pan, zoom and rotate the view.
Two different sets of data can be plotted down the borehole, selected from any of the choices already available in the Plan or Section views; including rock patterns, profiles, bar graphs, and more.
Display surface topography, or overlay an image or grid on the surface topography.
Display a Geosoft Voxel
Include a gridded image of data at one or more selected levels. The 3D tool plots to its own map, with optional legend. When plotted, the 3D viewer is launched automatically.

Users now have the ability to create 3D Voxel Models using the 3D Kriging gridding method. Additional tools are available to report and modify information about a Geosoft Voxel model, including statistical and coordinate system information.
Addition of a 3D math capability. The powerful math engine used for point data and grids now support voxel math. All of the extensive function operators supported by our math engine may now be applied to voxels.
A Voxel-Grid Clipper has been added. The capability allows you to clip a voxel to a gridded elevation surface. Clipping a voxel to two grids such as the top and bottom of alithologic unit is also supported.
Voxel import and export supported formats: XYZ, GDB, GOCAD and UBC
Support for the import/conversion of Datamine 3D block models to Geosoft voxel.
DH3D.gx now only loads a voxel. This is to improve performance. Voxels must be created using the voxel gridding menu.

Performance improvement with larger datasets
Ability to access settings to change the "General" default settings for your Target for ArcGIS environment. These settings are global variables, and remain set for a given installation of Target for ArcGIS.
New Voxel slicing. Allows users to plot a slice of a voxel on their plan or section.
New plotting type for point data. Profile plots using point data are very similar to profile plots using from-to data, except you will not get the stair-step behaviour expected for from-to intervals, where the value is constant over the depth interval. The plotting method begins by binning the data into depth bins equal in width to the discretization interval (set in the Preferences GX under "Hole discretization interval". If more than one value falls within a bin, the items are averaged. The curve is then interpolated through the bins containing no data, using the interpolation method and gap specified above. If averaging is applied, it is performed on the interpolated data.
