Create multiple isosurfaces and display them in the 3D Viewer with 50% transparency, except the inner-most surface, which is opaque.

What's New

Oasis montaj 8.1

Oasis montaj 8.1 includes new features that enhance the process of digitizing and editing geological interpretations. Add, edit, or delete geostring vertices, and to select pattern fills for geostrings. There are a number of new snapping options, including the ability to snap to existing interpretations and to snap on or off a section in edit mode.

This release includes significant upgrades to the Oasis montaj Induced Polarisation and GM-SYS 3D extensions. MAGMAP has an improved Reduction-to-the-pole (RTP) workflow.

New Features

Ease of Use

Control vertical extents of fence diagram

You can control the vertical extents of a fence diagram in sections by selecting the depth range. This enables you to plot the part of the hole you want to see instead of having to plot the entire hole.

New Feature

Survey design tool

Use the Survey Design Tool to quickly design a simple survey for ground geophysics or geochemical sampling. Plan a new survey by defining survey extents, line direction and spacing, sample spacing, and QA/QC samples. Use the reporting tools to calculate total line distance or number of samples, export a list for sample collection and preparation, or plot a map of the lines and samples.

Added Generalized Derivative grid filter

We have added a new generalized derivative filter option which can be useful for bringing out small details obscured by larger amplitude anomalies normally to the general geological structure. The generalized derivative is similar to the horizontal derivative filter, with the additional benefit that the angle of the filter is specified in 3D, through an Azimuth and a Dip angle. The curvature of the potential field response is a useful attribute that is used to enhance the signal along a specified 3D direction.

Esri ArcEngine 10.2

During installation, if you have a ArcEngine 10.1 or earlier installed or if you have no ESRI Desktop products installed, you will be prompted with the option to install ArcEngine 10.2.

3D Visualization

Added 3D path drawing to the 3D Viewer

If the X,Y,Z coordinates are identified in the database, you can plot a 3D trace of the survey path in the 3D viewer. This is particularly useful for an airborne survey over rugged terrain, enabling you to closely inspect the intersections or trajectory deviations.

Calculate a 3D distance

If your dataset has X,Y and Z coordinates set, you now have the option of calculating a 3D distance channel using the Z values (“slope chain” or “break chain” survey method). The 3D distance calculation reflects the true distance between recording points. In addition, you can also set the increasing direction of the distance along either the survey direction or the coordinate system axis. This new method is an option, the default is to use the existing distance channel tool, which calculates the horizontal distance using only X and Y coordinates.

Wireframing

Close a geostring

You can now close a geostring so it is not displayed on any of your maps.

Edit geostring vertices

Add, edit, or delete geostring vertices, including the ability to snap on or off section in edit mode.

Pattern Fill for Geostrings

Select a pattern fill from the Geosoft Pattern library for a geostring polygon or polyline.

Print maps with geostrings

Geostrings are now displayed on printed maps.

Snap to an existing interpretation

You can now snap to existing interpretations in an open geostring file while digitizing.

Snapping to To or From of a single from-to interval

Improved snapping options enable you to snap to either the To or From values (top or bottom of intervals), and individual intervals that are not connected to another from-to value.

Data Management

Increase the speed of voxel direct gridding

We optimized direct gridding to greatly improve the speed, enabling you to save time when gridding high volume 3D data such as GPR or lidar.
