Data Modeling

Data modeling is taking information and looking at it in different ways. A report is a form of data modeling, because it is a representation of data that can take on various output styles. Data modeling extrapolates data, meaning that in addition to displaying the data, it makes an “interpretation” of some kind.

One form of modeling is taking your data points and creating contoured surfaces. If you have a series of discrete points on your site, you can compile the data and try to read the patterns in between the data points. gINT has some basic modeling capabilities which we will review later, but it is not a modeling program. However, it can interface with programs that are.

Contouring and Modeling Data using gINT and Rockworks®

RockWorks® is a modeling and contouring program that offers tools for visualizing and modeling surface and sub-surface data. Rockworks uses a highly specialized input file format to import data from programs such as gINT. In particular, Rockworks employs certain tables and fields that do not have direct analogs in gINT, and employs concepts of “point” data (data at specific depths such as CPT data) and “interval” data (data corresponding to a range of depths such as sample and lithology data). Performing this conversion requires the creation of a fairly complex correspondence file, but once created, does not need to be modified.

Consult the Rockworks documentation for instructions on how to import and manipulate the data. We will only briefly describe some of the capabilities. (For more information about Rockworks, please visit RockWare’s Web site at www.rockware.com.) After import, the data looks as follows in the RockWorks Borehole Manager:

Notice the tabs for various data tables corresponding to the structure we created in the export file.

The following screen capture shows a model of chemical concentrations from PID data. Increasing concentration is represented with colors further from the purple and closer to the red end of the spectrum. Notice the site map and borehole numbers overlaid at the top.

By modeling specific PID ranges only, a clearer view of the high concentration areas is revealed:
