Encom has been working with Geosoft to improve the level of integration between Encom's potential field modeling products and the processing/interpretation environment provided by OASIS montaj. In the spirit of Greg's email below I have provided information on current solutions to the "Magnetic Type Curve" thread and some new cooperative developments. 1. The demo version of ModelVision Pro currently provides free forward modelling for both magnetic and gravity data for all supported 3D body types. You can compute the theoretical magnetic response at any latitude/declination for simple bodies or complex model combinations. Interest generated in this user group thread has prompted us to build a template (session file) that will provide a map, 3D perspective and NS and EW profiles across a simple model. Simply change the model characteristics to generate a new view. This will achieve the objective requested earlier by Keith Jones. . 2. The licensed version of ModelVision can be accessed through a GX function that is delivered with OASIS montaj. This GX can extract a line of gravity and magnetic data from Geosoft grids or transfer a subset of the line data stored within the OASIS database. ModelVision can be used to produce forward and inverse 3D models from the OASIS data. A new GX will be developed later this year to draw the outline view of the 3D models in an OASIS map view. . 3. QuickMag is a new product development that was previewed at the ASEG Conference in Perth. Work is progressing on the integration of this OASIS plugin to allow direct 3D magnetic interpretation from the OASIS map environment. An interpretation is performed by pointing at the anomaly that you wish to interpret. You then select a geological style for the 3D property distribution and QuickMag will isolate the anomaly from its neighbours, remove the 2D regional, interpret the best shape, position, depth and property and then draw the results as a graphic layer in your OASIS montaj map window. It will also include a drill hole designer and provide OLE capabilities for including each model interpretation within an MS Word document. . The concepts behind QuickMag were inspired by Geosoft's MAGMOD and the desire to provide quick solutions to the simpler 3D problems in potential field interpretation. As a result of the questions raised on this forum, we will also add the ability to generate a magnetic atlas style page with map, 3D view and NS & EW cross-sections.

We will let you know via this list, Technical Connection email newsletter and News & Views newsletter as 3rd party links and GXs become available. In the meantime, developers who have links and GXs in place can provide a brief description on this list provided that the details supplied are of an informational nature and deliver technical value to the Geosoft community. Greg Greg Hollyer Global Communication Officer Geosoft Inc. -----Original Message----- From: Jones, Keith To: '[EMAIL PROTECTED]' Sent: 3/26/00 8:26 AM Subject: [geonet]: Magnetic Type Curves for simple magnetic models Hi, Whilst Montaj has become more of a data processing package than an interpretation aid I have often felt that it would be useful to include a module to calculate a set of magnetic type curves for simple geometric shapes for various inclinations and declinations. A thin sheet model is a good example of a simple model that can be applied quite usefully in qualitative interpretation. As exploration has become more global it is not unusual to receive data from markedly different inclinations during the course of a single day. A simple plot to an A4(letter) scale to pin on the wall or to open as a seperate window I would find very useful. Does anyone else feel this would be a simple but useful interpretation aid?
