About this Release

Oasis montaj 8.2 is a scheduled software upgrade available to all maintained customers. In this release, we added new features and streamlined workflows to make working with grids, arrays, databases, and voxels an even faster and more efficient experience.

A new grid display tool enables you to preview colour ramps, add shadows, reverse the colour distribution, control the brightness, and add a custom colour legend bar. We also added new database shortcut keys, and the ability to rename files in Project Explorer to save you time. Also, Oasis montaj is now 64-bit aware, increasing the memory available to Oasis montaj and improving your ability to work with large files.

The wireframing workflow now includes the ability to merge geostrings and edit geostring and geosurface coordinate systems. When digitizing wireframes, the snapping circle and tooltip now indicate when you select a vertex or the edge of an existing geostring interpretation. New features for working with drillholes include improved vector slicing for sections and plans. When working with 3D views, you can now import DXF and GOCAD TSurf files directly into a geosurface file.

We consolidated a number of the section and array tools. Depth, time, frequency or velocity sampling increments can now be stored within an array channel, making array operations faster while reducing both the array database size and potential errors. You now also have the option to view array data along a true horizontal axis in the array viewer.

An expanded suite of voxel tools adds the ability to extract surfaces from a voxel that are parallel to a defined datum, such as topography or a geologic contact layer, which is useful for inspecting the geophysical or geological properties along a structure. In addition, you can also specify the order in which to fill a ​voxel, to more accurately represent the general geological structure. We also expanded our vector voxel tools, adding the ability for you to change the projection, window, inspect properties, adjust the transparency, and use math formulas with vector voxels.

GM-SYS 3D includes new calculations that provide faster and more accurate results as well as new support for closed 3D surfaces. MAGMAP adds a new streamlined Differential Reduction to the Pole (DRTP) filter. In VOXI Earth Modelling, the new constraint builder enables you to automatically generate drillhole constraints for a VOXI document, fast-tracking the previous 12-step process into a single tool, while eliminating potential errors at the same time. The drillhole extensions adds the ability to refresh a drillhole project from an acQuire database.

New Capabilities

Voxels

Extract parallel surfaces from voxel

You can extract and inspect the geophysical or geological properties from a voxel along a series of non-constant parallel datums. The master datum would typically be a topography or geologic structure grid.

New options for the voxel fill tool

You can now select the order in which each cardinal axis of a voxel is filled to more accurately represent the general geological structure. For example, when filling a horizontal layered earth model, you would interpolate horizontally layer by layer. All permutations are supported.

Support for additional vector voxel operations

The voxel tools now support additional vector voxel operations including the ability to change the projection, window, inspect the properties, or adjust the transparency of a vector voxel.

Workflow Improvements

New 64-bit support

On a 64-bit system, Geosoft desktop applications, including Oasis montaj and Target, are now aware of and will use the full 4 GB of RAM provided by the operating system, instead of the 2 GB limit for 32 bit applications. This access to additional memory improves our ability to work with larger files

New database shortcut keys

We've added some new keyboard shortcuts to help you work more efficiently with databases. You can save the changes to a database by simply pressing CTRL+S. You can cut (CTRL+X), copy (CTRL+C), and paste (CTRL+V) channel math formulae to and from the database formula bar located along the bottom of the current database. This handy option allows you to easily transfer a very long and complex equation that you have already built to a different channel and reuse or edit it.

New DXF import options for 2D maps

New AutoCAD DXF importer provides all the controls for importing and displaying one or many DXF files on a 2D map. Plot the DXF layers to a new or existing map as a either a single group or as multiple groups. You can use the existing DXF file colours or pick a new colour for all the lines and polygons. When creating a new map you can specify the map name, scale, and the projection type (plan view, E-W section view, N-S section view).

Rename files in Project Explorer

You can now rename any grids, voxels, databases, or maps that are loaded in your Oasis montaj project directly from the Project Explorer pane. Click on the file to select it, then click again or press F2 and type the new name.​​ Oasis montaj is aware of the file structure and will also rename all the associated files as well.​​

Section surround

Oasis montaj recognizes if a grid is in plan or section view, and then displays the appropriate surrounds tool. The section surround tool applies georeferenced annotations, recognizes the vertical exaggeration, and plots a plan index view of the section trace.

Array Data

Embed increment information into an array database channel

When recording geophysical array data, the properties (depth, elevation, time, frequency or velocity) are normally set by the instrument and use the same increment for all data points. If this is the case, the increment information for the array can now be stored in the channel itself instead of having to be stored in a separate channel. Embedding the information in the array channel saves disk space and computation time while making your data more concise and minimizing the potential for error.​​

Pack and unpack array increment information in the data array header

To ensure for all types of array data, we offer the ability to pack (embed) sampling increment information from a property channel into the data array header or conversely, to extract a property from the information packed in an array channel. These two options provide compatibility for both the old (separate property channel) and new (packed in header) formats.

Tools that act on data arrays have been modified to be aware of how the increment information is stored, and act accordingly. A separate increment array channel will continue to be supported to honour uneven increment spacing among data points.

Sampling increment information in data arrays

We've made it simpler to work with array channels in your database. The sampling increment information for a data array can now be packed into data array itself so you do not need a separate property channel in the database in order to specify the array increments.

You can pack sampling increment information from a property channel into the data array header or conversely, extract a property array from the information packed in a data array. These two options provide compatibility for working with both the old (separate property channel) and new (packed in header) formats.

All of the tools in Oasis montaj that work with array data will recognize if the sampling inforation is stored in the array data or not and adjust accordingly.

View Array Channel profiles on true property axis

The ability to embed increment information in arrays means that you can now toggle the display of the horizontal axis of an array between a simple indexed presentation and a true horizontal view, which provides a more realistic view of the array profile.

3D Visualization

Improved DXF import in 3D Viewer

You can now import multiple AutoCAD DXF files into a 3D view at once. In addition to importing the DXF files as map groups, you can create a new geosurface using the imported DXF files or add to an existing geosurface file.

Improved GOCAD T-Surface import in 3D Viewer

When importing a GOCAD T-Surface file into the 3D Viewer, you can now import the GOCAD file to a new geosurface, append it to an existing one, or use the previous option to import as map groups in the 3D View. You can also specify whether to invert the Z-axis.

Wireframing

Modify a geostring or geosurface coordinate system

You can now add or edit the coordinate system for geostrings and geosurfaces.

New import option to merge geostrings

You can now import features from another geostring into the current geostring. This enables you to combine interpretations from different projects or others in your team.​

Wireframing snap to vertex

When snapping to an existing geostring interpretation, the cursor snapping circle and tooltip will change to indicate that a vertex or edge is selected.

Grid Display

Colour legend bar

You can now access all the vertical and horizontal colour legend bar display options from a single tool. In addition to annotating the colour bar at colour breaks, you can now also annotate the bar using your own specified increments. You can access this tool directly or through the new colour grid display tool.

Display a map in a rotated coordinate system

You can now display data with a rotated coordinate system on a map. The ability to specify a rotation angle is particularly useful in cases where you want to display a specific trend such as the predominant geologic structure. If the coordinate system of a grid is rotated, you can either plot it in a rotated coordinate system with its Y axis along the rotation angle or as before with its Y axis along Northing.

New colour grid display options

A consolidated grid display tool provides all the options in a single dialog so you can set everything before you display your grid. The new options include:

  • New colour ramps for more varied colour options.
  • All the colour ramps now include a preview so you can see the colours before displaying your grid.
  • Colour ramps are organized into logical groups such as geophysics, topography, heat maps, and favourites so you can select quickly colours based on the type of data you want to present.
  • Quickly flip the colour ramp distribution.
  • Easily set and adjust the brightness.
  • Choose an un-interpolated colour display.
  • Apply an optional shadow effect.
  • Trigger the colour legend tool to add a colour legend bar.

 

Oasis montaj Extensions

Drillhole Plotting

Improved vector slicing for drillhole sections and plans

In addition to slicing a DXF or shapefile, you now have the ability to slice a geosurface in section or plan view. This makes it easy to review a geosurface you've created with the wireframing tools by viewing it from different orientations. ​​You can select multiple vector files and have the option to edit the colour and fill attributes for lines and polygons.​

Refresh an acQuire drillhole project

You can now refresh a drillhole project from an acQuire database. When refreshing the data, you have the option to overwrite the drillhole databases or append new drillholes to the project. This enables you to easily refresh your drillhole projects while preserving the existing configuration of any custom data fields.

GM-SYS 3D

Faster Calculations

We have rewritten our calculations to optimize them so that they are faster, give better results, and are more robust, providing you with a better user experience with shorter processing times.

Forward Gravity Calculation for Draped Surveys

A new gravity calculation method provides more accurate results. This enables you to work on draped surveys without upward continuation and take advantage of the full resolving power of your surveys.

Support for closed 3D surfaces in GM-SYS 3D models

​Using closed 3D surfaces, you may represent arbitrarily-shaped bodies of any complexity in the models. ​​More accurately represent geologic units that aren't easily represented by subhorizontal grids, such as convoluted and discontinuous allochthonous salt, dikes & plutons, or cave systems.​

MAGMAP

Improved the Differential Reduction to the Pole filter in MAGMAP

Now when using the Differential Reduction to the Pole (DRTP) filter in MAGMAP, you only need to provide the date of the survey. The inclination and declination grids used by the filter are automatically calculated in the background and saved for future use.

VOXI Earth Modelling

Added the drillhole constraints builder to VOXI

You can now build a set of 2 VOXI constraints automatically by leveraging the geophysical properties of the drillhole. Although in the past you could create these constraints using the 3D math tool, it was labour-intensive and prone to errors. If you know the geophysical property along drillhole path, you can now introduce it in VOXI and have it control the inversion. The constraint builder will create the constraints and load them into the VOXI document.
