C Tech Application Launcher

Follow the steps in this article to run the C Tech Application Launcher.


1.Select C Tech Application Launcher from the EQuIS menu on the EQuIS for ArcGIS toolbar.

2.A dialog appears that allows you to choose chemical and/or geology data to export to EVS, EVS Professional, MAS or MVS (hereafter referred to as EVS for simplicity). Right-click on the various controls on the dialog and select What's This? to learn more about each option.

3.Select any chemical layers in the current map that were created with the EQuIS EZView LayerBuilder module. If a crosstab query was created, then all analytes may be exported or a single analyte may be selected in the drop-down list of available fields in the layer.

4.If features are selected on the map for the selected chemical layer, the check box will be enabled so that only those selected locations will have data exported.

5.Choose between the GWC or CSV formats.

6.Geology data can also be exported for any connected EQuIS Geology project in PGF of GEO format. EQuIS Geology must be installed to use this module.
If only chemical data or only geology data was exported, the C Tech Preview and Launch Application will display those sample application templates for the file type exported. As of version 6.1, there is only one sample template provided by C Tech in the launcher that uses the PGF format; therefore, to see those templates which use chem/geo combinations of input files, you must select the GEO format.
For more information see C Tech Application Launcher concepts.




Both geology and chemistry data can be exported for use in C Tech's EVS/MVS products.


Geology data can be exported in the uninterpreted pre-geology format (*.PGF) or interpreted *.GEO format. The *.PGF format is compatible with the Geologic Indicator Kriging (GIK) found in the Krige3D module in EVS Pro/MVS. The recommended approach is to export as PGF format, and use the interactive tools or GIK to define the geologic layers. The *.GEO formats take significantly longer to create than the PGF option, since there is some interpretation logic being performed on the data.


By selecting the advanced geology exports user preference (EQuIS>Options, select Geology->Advanced section), the same export options in EQuIS Geology are made available in EQuIS for ArcGIS, i.e. geologic units may be exported instead of just material types.


Chemistry data can be exported from either the EQuIS Chemistry or Geology's geochemistry tables for layers generated using the EQuIS layer builder (created from within ArcGIS environment only). These may be either single chemical layers or chemical crosstab layers for multiple chemicals within a chemical group that you define with EQuIS Chemistry or Geology. Metadata is stored internally for the layers that are used by the EVS chemical export module, so it is important that if users wish to export chemical data to EVS, they choose the 'static' layer type instead of dynamic in the user options layer builder section. Dynamic (OLE DB XY Event layers) cannot have metadata due to ArcGIS limitations, and therefore cannot be exported, and will not be recognized as a chemical layer when performing the EVS exports.
