March 2011 News
There are always new improvements coming to EMIGMA but we mention here some of the more notable additions during the fall of 2010 and early winter 2011.
New Magnetic Inversion Algorithms and Tools
Partially because of our own needs for improved magnetic inversions for our extensive consulting work in the gold exploration industry, we have done a complete re-work of the inversion tools including many new improvements.
Last year, we released 2 new fast matrix inversions tools to allow both faster and larger inversion processes. Last fall the inversion algorithms were reworked to be faster, more stable and allow larger inversion tasks. But even more importantly they were upgraded to allow joint inversion of multiple data sets. Thus, the user can now jointly invert, for example, both ground and airborne data with or without magnetic gradients either measured or derived from FFT grids. Additionally, we have entirely re-worked the interface to allow an easier grid definition with visual aids. In addition, we have added to the ability to use both linear and exponential vertical grid definition, the ability to mix different linear depth thicknesses for different vertical depths of the inversion grids. Thus, one can define thin shallow grid definition with intermediate thicknesses at intermediate depths and thicker thicknesses at depth.
Additionally to these improvements, we have added the ability to constrain the model with borehole susceptibility information as well as ground samples of susceptibility. Also, added is the ability to process the inversion grids to remove cells of defined sensitivity. Thus, one can remove weak susceptibility cells to focus on the main structures, view the refined grid and re-compute the response of the refined grid.
The result is a fast, stable, accurate and flexible inversion product which is very suited to enhanced resolution of the derived structures.
Static Borehole Data and Borehole Geometry Imports
For a longtime, we have been able to model borehole total field magnetic and vector data as well as gravity data. Now, you may import the data for comparison to models and utilize in your gravity and magnetic inversions.
In addition, we have augmented our tools for importing the borehole geometries which also allows you to import other borehole data. This allows you to view the borehole geometries in conjunction with your models as well as with our new tools for importing mine workings into your visual displays.
New Polyhedral Structure Builders
We have added three new tools for importing structure into a complex polyhedral volume. First, we have augmented and upgraded our tools for importing GEMCOM .tri files allowing one to import geological models from several applications most notably from GEMCOM and GoCad. Secondly, we have added the ability to import three dimensional volumes from a QCTool grid. This for example, allows one to build a topography model in QCTool and then export to EMIGMA as a 3D volume. But, generally it allows one to import a 3D surface into EMIGMA and give it an arbitrary thickness. Finally, one is able to import a polyhedral model based upon an ASCII 2D geometry and give the structure a radius. This is most useful in importing such things as mine workings into EMIGMA to view in combination with models and borehole geometries.
Additionally, we have moved these tools into a direct capability from the main EMIGMA database interface.
Crone Borehole TEM and Magnetic Data imports: Crone TEM data offers some very large advantages to other impulse data in that it provides accurate and reliable measurements during the ramp (on-time) with the advantages of impulse measurements as well as offering 3-component magnetic data.
We have augmented our imports and functionality in several ways. First, the user may import the raw (un-averaged TEM) data and perform the borehole rotations either from Crone data information or other borehole geometry information. Secondly, one can import the borehole magnetic data from the raw files and de-rotate without the need for Crone processed magnetic files.
We have been using Crone data extensively in our own consulting services and find these tools extremely convenient and effective.
Shortly, the user will be able to import the Crone MMR data and use it with our new MMR modeling and display tools to be available by summer 2011. If you have need to model this type of MMR data please contact us at email@example.com
We are always augmenting our processing tools to meet the need for enhanced data processing. Recently, we have added 3 new tools
Convert units: This allows the user to convert units of both measured and simulated data to other data units and then continue with processing, modeling or inversion.
Data Outlier Removal: a convenient tool for removing outliers in your data. User selectable ranges are allowed.
Vector Rotations: Often it is necessary to rotate your vector data. This tool allows an accurate, flexible and user-friendly way to perform these operations.
PROMIS FEM imports and tools: The new PROMIS FEM equipment is easy to use and accurate piece of equipment allowing one to rapidly collect accurate multi-frequency and multi-separation FEM data to replace the aging Max-Min instrument. Our own tests of the instrument show it to be a reliable and efficient instrument. As such, we have improved our tools to import and utilize the data both for modeling and inversion.
Vector Magnetic Data Imports, Modeling and Inversions: We have extended our magnetic imports to allow import of vector magnetic data for either ground, airborne or borehole data. The imported data then allows easy modeling and inversion setups.
Gradient Gravity Data Imports, Modeling and Inversions: We have improved our gravity imports to allow import of any or all of the tensor components and then the data can be used directly in our modeling and inversion tools.
Upgrades to Resistivity/IP Imports: Upgrades have been made to import such data in either the generic Geosoft formats or ELREC 6 formats or Zonge GDP_32 formats. This allows quick access to our display tools whether as plots, sections or 3D visualization as well as for use with our 2D/3D IP/Resistivity modeling or 1D or 3D Resistivity inversions.
Survey Editor Upgrades: Our survey editor tool is very useful for reviewing and editing your surveys. New tools allow displays of sources as well as the co-ordinates of the vertices of your source.
Mapping Upgrades: New tools allow the integration of maps particularly with transparencies and then outputting to MapInfo or Arc Map Geotiff formats.
We trust you will enjoy and appreciate these new features in our sub-release EMIGMA V8.5.5.
