EVS Groundwater Chemistry File Creation in ArcGIS

Note: If you are not a licensed user, you may build data files, but you will not be able to utilize them in EVS or MVS because the files you create will not be password protected (allowing them to be used in a demo version). Instead, we recommend that you review Loading Existing EVS Geology or Chemistry Files or&ldots;.

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.

CREATING A GROUNDWATER CHEMISTRY FILE:

The following section will outline how to build an EVS Groundwater chemistry file (.gwc) with ArcGIS. This topic does not reference the included database which does not have an example of a GWC file. However, the procedure is virtually identical to creating a CSV file except that there is one additional elevation field.

To see the format for a GWC file click here: Grounwater Chemistry File Format

Now that the extension is loaded, click on the "Create EVS Data File" button to reveal:

Select GWC as the file type:

From this menu, you select the layers and features from which you want to extract chemistry data. You can also choose whether to include all features of a layer or only the selected features.

The window is nearly identical to the Chemistry File Creation window, with the addition of fields for the Z Bottom and Max Gap parameters in GWC files.
