Geology & Chemistry File FormatsLicensed users have the option of launching with files that are created using the extension OR existing data files that are selected as shown in this topic.
If you have existing EVS geology or chemistry files you can select any
of the EVS file types from each of the "Create" options on the
EVS pull-down menu. For each option there is a button named "Load
existing file-type file"
(for example, the button: "Load Existing CSV File" appears within
the Create CSV File dialogue window). The discussion of EVS file formats
can be viewed by clicking here: Geology & Chemistry File Formats
To demonstrate this approach let’s Load a geology file and a chemistry file, thus enabling all of the EVS For ArcView applications.
First, choose the following CSV file by selecting EVSàCreate CSV File:
Then choose a geology file so we will have application choices that include both chemistry and geology applications. For this example we will choose a .GMF file (though the applications will use either GMF or GEO files. Pick the following GMF file by selecting EVSàCreate GMF File:
What have you accomplished by selecting both a chemistry file and a geology file?
By making or choosing both data types, the ArcView extension will now make available nearly all the applications provided with EVS for ArcView (or whatever version of C Tech software you are working with). Once you choose Launch Application from the EVS pull-down you'll see there are applications for viewing chemistry mapped into geologic layers, posting chemistry data, rendering geologic layers, and much more. If you had only chosen a CSV file, you would only be shown the group of applications that only require chemistry data. Similarly, if you had chosen only a geology file (GMF or GEO) you would only have geology applications available.
If you are a licensed user, you should UNCHECK "Run in Demo Mode".
To see an example of an application utilizing both geology and chemistry data, make the following selection from the C Tech Application Preview and Launch Menu:
Once you've launched the application in EVS, try opening the Solid_3D user interface (select this from the Modules pull-down list) and change the Iso Level to 1.0. Now rotate the model by either selecting Az El, or using your left mouse in the Viewer screen. Now open Explode_and_Scale from the Modules list and toggle the layer selectors (Hex0, Hex1, etc.). This is the power of the finite element modeling EVS, whereby any layer configuration can be mapped in 3 dimensions, AND the kriged chemistry concentrations can be mapped to this same mesh. Also, any layer can be inspected independent from the rest, for calculating volumetrics, mapping thickness versus concentration, or many other possibilities.
