Oasis montaj Viewer is a free, easy-to-use program that allows anyone to view, share, and print published Geosoft grid (.grd) and database (.gdb) files. The viewer can also be used to convert grids and images to a variety of supported data formats, including AutoCAD, ArcVIew, ER Mapper, TIF, and many more.
The goal of the Oasis montaj Viewer is to allow anyone, within your organization or within the geoscience community, to access high-quality maps created by Oasis montaj, Geosoft Target or Target for ArcGIS, and to freely share earth science results and ideas. Norma P Nickerson.
Release Notes About this Release Oasis montaj 7.2 is a scheduled software upgrade available to all 7.1 maintained customers. The upgrade includes new software capabilities, improvements and corrects reported issues for Oasis montaj, Oasis montaj Extensions, and Geosoft Plus Extensions.
System Requirements This release includes enhanced support for Windows 7. Geosoft Oasis montaj will run on Windows XP SP3 (32 Bit), Windows Vista (32 and 64 Bit) and Windows 7 (32 and 64 Bit) operating systems. See detailed. New Capabilities Ease of Use Improvements Shadow cursor support has been added to all data views within a map. Use the shadow cursor to link multiple data views or a section view and a plan view in the same map.
Shadow cursors work across different Geosoft Project Files (GPF). Map/Grid Relative Paths Improved handling of relative paths for rasters in maps makes opening maps more efficient.
When opening a map where the grids have been moved from their original file locations, the path to the grids are now stored relatively so that they will be discovered automatically. Efficiently create grids for many channels from multi-element geochemical data, or multichannel array data such as EM. Multiple Channel Gridding is available for Minimum Curvature or Bi-Directional Line Gridding algorithms.
The same parameters are applied to all selected channels. Menu Updates The Math, Math Expression, and Load All Channels GXs have been added to the Scripting submenu, making it easier to access these items. Load All Channels is used to display new channels created within a script. The Math and Math Expression functions are an alternative to the Channel Math tool and are recorded in detail when scripting, making it easier to edit in the script file.
We have improved map group names in the Map View/Group Manager. The character limit for group names has been extended to 1024 characters.
This is useful when identifying groups in maps with longer descriptive names and distinguishing between groups with very similar names. New selection tools provide new ways to transfer channels to and from arrays. Use 'Array to Database Channels' to quickly display selected elements from an array as channels, or use 'Database Channels to Array' to create an array from a selection of channels in a database. Metadata Improvements A new feature, Metadata Lineage, records how Geosoft document files are created. Database Lineage has been streamlined to only record database creation tasks.
A scriptable option has also been added to better manage the creation of metadata updates when using scripts. Advanced 3D Subsurface Visualisation We have added an option to display a Colour Legend Bar for voxels to the layout of a 3D view. GOCAD Voxet orientation support The GOCAD Voxet conversion to Geosoft Voxel has been expanded to fully support the orientation parameters of GOCAD Voxet files. This ensures that voxets are correctly oriented and located in the Geosoft 3D Viewer. Sample a Voxel to GDB locations The new Sample a Voxel capability allows values in Geosoft voxels to be queried using Geosoft databases with X,Y,Z coordinates. Use this to compare original database values to interpolated voxel values or add a new channel containing voxel values to databases containing different data types.
New options to the 3D Gridding tool allow Log and Log/Linear interpolation when creating voxels. Using the logarithm of the original values can be a very effective way to reduce distortion in highly skewed data, such as geochemical assays. Master Voxel The Master Voxel utility allows you to create a uniform voxel of any size, orientation, and coordinate system.
A Master Voxel can define the dimensions of the resulting voxel when resampling and completing voxel math operations. Master Grid The Master Grid utility lets you create a uniform grid of any size and coordinate system for Grid and Voxel Math operations. A Master Grid may also be used in GMSYS-3D for creating the Index Grid that defines the model. Data Access and Data Support Seeker combines capabilities from DAP Find Data and Dapple interfaces. It replaces our two 'Find Data' options with a 3-step workflow. Search criteria can be used to refine results, retrieve and use them in your local mapping environment.
Seeker is available in all Geosoft applications and plug-ins.Watch the A filtering capability for our ODBC tools has been added for surface data GDBs and Target drillhole projects. Access the drillhole databases or surface data that you need without SQL query knowledge.
Also connect to other drillhole databases like DataShed and Century systems. JPEG 2000 Support We have added support for JPEG 2000 (.JP2 and.J2K). Conversion to JPEG 2000 can be found under Map Export formats. Similar to GeoTIFF format, JPEG 2000 supports embedded coordinate system information. Transparency for sharing grid images that are not rectangular is also supported now. ASEG-GDF2 The ASEG import has been updated to support ASEG-GDF2 format. The creates a user readable text file containing information regarding data collection such as geographic coordinate system and location.
This information is imported and can be viewed in the metadata under Abstract. Upon export the description information, if present, is saved into a text file. Excel 2007 Added support for Excel 2007 (.xlsx) files. Updates for Oasis montaj software extensions. Geophysics New support for sections has been added to montaj Geophysics. Create sections from survey lines with bends or curves and display them in 2D or 3D views as either grids or pixel plots. This new section support provides accurate geospatial representation by ensuring that data are correctly positioned along the survey line.
Sections are dynamically linked to all other data including plan maps, sections and 3D views. See about creating sections. Sample a Voxel to GDB locations The new Sample a Voxel capability enables you to query the values in a Geosoft voxel using a Geosoft databases with X, Y, Z coordinates in points or arrays. This capability is useful when sampling a voxel to an existing survey line, or can be used to add a new channel containing voxel values to a database that contains a different data type (e.g.
Combining data from different inversion models). A Constrained Linear Prediction (CLP) extrapolation method has been added to the 1D-FFT expansion routine. It is useful in minimizing edge effects when working with data containing systematic high frequency interference.
Geochemistry Duplicate sample identification has been simplified and improved. The Duplicate indicator column now contains the original sample number of the parent sample. This enables you to have multiple duplicates that reference a single parent sample. Log options for Box plots Box plot graphs have been improved with the addition of a new option for plotting a logarithmic scale.
Drillhole Length Weighted Mean Calculation By highlighting a selected section of your drillhole database, you can now calculate Length and Length Weighted Mean values. This makes it easy to quickly find out the length of several irregularly spaced samples as well as the length weighted mean assay value. Significant Intersections Report enables geologists to quickly identify drill core intervals that have significant assays based on minimum cut-off length and grade. This is useful for highlighting successful drilling results visually within sections, maps or 3D views, and is exportable as a tabular report.
Real world coordinates in Fence Diagrams In Fence Diagrams, we now support true geospatial positioning. The status bar reports the correct 3D location of the cursor position when moving within the fence section, and the dynamic linking from Fence Diagrams now works consistently with other map views. MAGMAP Filtering The new Multistep Expansion (MSE) algorithm option in Gridfill is useful for minimizing artefacts when working with grids having jagged edges and short wavelength features. The MSE filled area has a more natural look and is truer to the power spectra of the original data. GM-SYS Profile Velocity/Density conversion This addition enables easy conversion between density and velocity allowing selection from ten of the most commonly-used, published relationships. Seismic interpreters commonly provide velocity models to potential-field professionals as an exchange format.
Velocity information must then be converted to density using known relationships between parameters. The user-interface has been rewritten to improve workflow, extensibility, and efficiency. The new interface is comfortably familiar with a new look-and-feel: new icons, cleaner organization for the toolbars, and a newly dockable floating Action toolbar.
Access IGRFPT.GX IGRFPT.GX calculates the Geomagnetic Reference Field for specific locations and dates. This is required to calculate the magnetic response of a model. IGRFPT.GX replaces the NGRF.exe utility.
Geosoft Oasis Montaj V7.2
The upgraded IGRFPT.GX is a more robust implementation and is now easily accessible from the GM-SYS Profile menu. For doing easier quality control of your model, you can now sort the Block Spreadsheet by any block parameter (e.g. Block Name or density).
You can also copy one or more properties from a block and paste those properties into any other block(s). GM-SYS 3D Draped surface FFT gravity calculations We have removed the limitation that required upward-continuation of your data to a constant elevation. GM-SYS 3D will now calculate the gravity response of a model on a draped surface, typically topography. This new capability allows for a more accurate and detailed model. To improve your workflow the GM-SYS 3D menu has been reorganized into two separate menus. GM-SYS 3D: contains model creation and basic model manipulation including open/close/export functionality. GM-SYS 3D Tools: contains the editing, display, and calculation capabilities.
Space-domain vertical prism calculation utilities (Gbox and MBox) This new utility allows you to perform forward calculations for simple vertical prisms. This in an implementation of Blakely's GBox (Gravity) and MBox (Magnetic) forward calculations for testing simple theoretical models. SEG-Y Reader Improved XML Configuration SEG-Y Reader now saves the configuration data in Geosoft-standard XML Metadata format allowing the SEG-Y Reader to automatically recognize the file format and load it.
Making it faster and easier to work with SEG-Y files. New CET Grid Analysis Extension The new contains tools for texture analysis, phase analysis, and structure detection.
These versatile algorithms are useful for grid texture analysis, lineament detection, edge detection, and thresholding. Oasis montaj Plus Extensions PotentQ New version, primarily with bug fixes. Praga 4 New version, primarily with bug fixes.
