About this Release
Target 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 and the ability to refresh an acQuire drillhole project. 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.
How to update
Online installs for each product are available through the Check for updates option within the software and from the download link at the top of this page. If you require the upgrade on a DVD, you can request one here.
Target 8.2 runs on Windows 8.1 (32 and 64 bit), Windows 8 (32 and 64 bit), Windows 7 (recommended) (32 and 64 bit) , Windows XP SP3 (32 bit), or Windows Vista (32 and 64 bit) operating systems. See detailed System Requirements
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.
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.
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.
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.
Modify a geostring or geosurface coordinate system
New import option to merge geostrings
Wireframing snap to vertex
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.
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.
New colour grid display options
- 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.
