Brief Outlook for EMIGMA

For several years, one of our primary considerations for EMIGMA has been the addition of basic processing and mapping features. Many features have been included in these areas and we will continue to improve the processing features as well as developing faster methods to perform various processing aspects. Also, in the last several years, we have focused on the development of various inversion techniques for most data types. While, we will continue to improve and enhance our inversion applications, we are now in the process of returning to our roots to enhance and extend our forward modeling (simulation) algorithms.

One of the issues which has required our attention is to extend the ability of EMIGMA to manage not only the geophysical setup of your data allowing for automated modeling and inversion but the inclusion of all the associated data channels that may be crucial for your proper understanding of the inversion and simulation results. To this end, we have developed and continue to further develop our new software package QCTool. QCTool is capable of handling huge amounts of data and performing many basic and extended data processing functionalities. The combination of QCTool with EMIGMA will resolve our ultimate objective. Airborne TEM, ZTEM and MT/VLFR data can now be imported directly from the .qct format and we will be working on more direct QCTool exports to EMIGMA. This will allow for ready imports of quite a variety of relevant data into EMIGMA after having passed them through appropriate quality control and processing in QCTool. We are also working on the direct import of the other associated data channels into EMIGMA and the possibility of their display and analyses in graphical applications. Our latest version, released in 2010, offers enhancements to EMIGMA V8.1 which was released in the spring of 2008. EMIGMA is now fully compatible with Vista and Windows 7 for both the 32-bit and 64-bit versions.

Many EMIGMA licenses are now shipped with QCTool included. However, QCTool is available from our websites for a free 30 days use and it only costs $300. In the meantime we will be enhancing the linkages between the two packages to provide you with this " all-in-one " smart and easy-to-use software platform.

Another important consideration for EMIGMA is to increase its capability of handling and processing large datasets whether collected on the ground or in the air. To this end, we have been extending our principal algorithms and approaches to have them work faster and more efficiently. Great progress has already been made with regard to modeling and inversion solutions. A major new design was ready in 2009 but limited to UXO functionality. The next version of this will be for potential fields and is to be called EMIGMA 9. Sometime in 2011, EMIGMA 10 incorporating all functionalities in this new design will be available.
