button to the right of the View
EVS Data button in the ArcMap window. This button launches the
C Tech Application Preview and Launch Menu. At this point you can select
"Launch Application" from the button to the right of the View
EVS Data button in the ArcMap window. This button launches the
C Tech Application Preview and Launch Menu.
When it opens, select EVS for ArcView (or any higher version if you wish) as the "Version to Run" or if you are a licensed user, choose your appropriate version. If you choose another version you will see additional applications besides those shown in the figures in this topic.
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 by choosing the "Geology and Chem. Applications" Category and selecting the Application Name shown below:
If you are a demo user be sure to CHECK "Run in Demo Mode" before Launching Applications. The demo version will not allow you to analyze or visualize data files created with the extension because they are not password protected. When "Run in Demo Mode" is checked, the default data files for each application (ones with passwords) will be used.
Please note: If you are a licensed user, you should UNCHECK "Run in Demo Mode".
When you click Launch EVS for ArcView, the application you selected will be modified to use the data files you created or specified. Then, EVS (or MVS) is launched running this application, with all parameters automatically set and all modules running. The C Tech Viewer and message console will appear with the application running. After kriging is done you will see the following in your Viewer:
Applications always come up in a "Top" view because the application doesn't have any view specified. This is necessary to accommodate the unknown size and extent of the incoming data. You can always use Az-El to set any view.
If we select Az-El and choose 195 Azimuth (20 deg elevation) we will see:
Note that the module selector list is a pull down menu on the Viewer (as well as the network editor). You have access to all parameters in all of the modules in the application. (Allowing you to re-krige or change any settings). The bottom of the viewer shows the currently selected module. When applications are first loaded, the selected module may not be visible. To view the user interface for any module, merely select it in the pull down menu.
Now that you’re 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 (0 Hex Fill, 1 Hex Silt, 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.
After running a particular application in EVS for ArcGIS (or any other version of C Tech’s software), you can return to the C Tech Application Preview and Launch Menu by selecting it in the File menu in the C Tech main window. When you return, the C Tech Application Preview and Launch Menu will look a little different because you are not given the choice of what software version to run (since you are already running it!). Upon returning you will have the same application choices as before and the window will look like:
When you click OK, the application you selected will run. The C Tech Viewer and message console will appear and you should see the following:
