Volumetrics Study: Studio vs. MVS

Prior to the formal release of Studio, we did a comprehensive volumetrics study because we were making significant changes to both volumetrics and subsetting (e.g. plume) modules in Studio.  In that study we looked at our new Studio algorithms compared with MVS as a function of grid resolution. We’ve always known that as you increase the resolution of your model, the accuracy improves and we always see volumetrics results approach an asymptotic “theoretical” value as the grid resolution is increased. Our new algorithms in Studio work dramatically better than MVS, but we didn’t make a big deal about it, primarily out of concern that by saying that Studio is much better, we could be misconstrued as saying that MVS was somehow WRONG before.  In reality, everything we do (and by reference, everything you do with our software) is geostatistical by nature.  It is a best estimate.  And usually it is only a fair estimate because of data quality. In our study we focused on Chemical Mass (not plume volume) of the entire model, as well as X, Y, Z CG and Average Concentration.  If you additionally consider subsetting (plumes) they will effectively decrease the model resolution since the subset upon which you are computing volumetrics is a portion of your total model that has a lower effective resolution.  The higher the subsetting (plume) level, the lower the effective resolution and the poorer your results may be. The tables below summarize our results which are also given as graphs.  For both Studio and MVS we did the calculations with and without Adaptive Gridding (AG) for the total number of nodes ranging from 30,000 to nearly 8 million.  For all cases, we are computing volumetrics on the entire grid without any subsetting.   Both Studio and MVS reported exactly the same volume for the full grid which was 350,950 cubic meters.  This was not affected by resolution nor by adaptive gridding. In our study, there were very minor if any differences in volumes or plume volumes between Studio and MVS.  The biggest differences seen were in the computation of Chemical Mass and those parameters derived from chemical mass. The first, and perhaps most surprising observation of our study is how...

New Training Videos: 3D Kriging and Advanced Gridding

We have just posted two new series of public training videos for Earth Volumetric Studio. The first series is on 3D Kriging in three parts: Part One focuses on krig_3d, some of its basic properties and discusses the limitations of its flat-topped rectilinear gridding in anticipation of Part Two. Part Two demonstrates how easy it is to incorporate krig_3d_geology when doing 3D kriging so that your grid is conformal to site topography and/or includes site stratigraphy. Part Three introduces draw_lines and triangulate_polygons to create a user-defined area, which we then use area_cut and intersection to subset the model to show the region inside or outside of that area. Finally, we explore volumetrics and its important settings to ensure that volume and mass analysis is performed correctly. The second series is on Advanced Gridding: Part One introduces krig_3d_geology’s Finite Difference Gridding option which provides a very flexible means to create a rotated rectangular 2D grid with complex cell size distributions. This video covers it basic functionality and is recommended for all users. Part Two continues Part One to add area_cut, polyline_spline and triangulate_polygons in order to create a grid that is confined to a region which closely conforms to the concave hull of a riverine dataset. It is recommended for advanced users and those needing more control over the areal extents of their models. Both video series are available on the public Training Videos page....

Stratigraphic Geology Training Video Series Posted

We have just posted a new series of four training videos on modeling Stratigraphic Geology.  The first three cover rather basic topics related to the creation of stratigraphic geologic models, but the fourth and final video in the series tackles the more complex horizon_ranking module and how to use it to control hierarchy when you have intersecting stratigraphic horizons. All four videos are available on the public Training Videos...

New Training Video: Animation in Earth Volumetric Studio

There is a new addition to the Earth Volumetric Studio Training Videos. The Animation in Earth Volumetric Studio video demonstrates the basic procedure for creating animations. We begin with a beginner application and make some simple modifications to it before learning the step-by-step procedures for creating a high-quality AVI which is included (3 times) at the end of the...
