Before You Begin
Install the Sample Projects before starting the workbooks. The workbooks use Sample Projects for their data and applications. Download them from ctech.com/downloads.
This section outlines the recommended learning path for new EVS users. Each workbook builds on the previous one, progressing from interface basics through data preparation, modeling, and delivery.
Workbooks
Earth Volumetric Studio Basics — Get hands-on with the EVS interface. Load applications, navigate the 3D viewer with mouse controls (rotate, zoom, pan), use azimuth and inclination for precise views, inspect statistics on field ports, interactively change plume levels, and organize projects for portability.
2D Estimation — Build a kriging-based 2D estimation application from scratch. Instance modules, connect them into a data flow, run the application, and refine output with subsetting to explore concentration thresholds.
Exporting from Excel to C Tech File Formats — Convert Excel spreadsheet data into EVS-compatible file formats. Covers creating AIDV (interval analyte), APDV (point analyte), GEO (stratigraphic horizons), and PGF (lithology) files using the C Tech Data Exporter.
3D Data Requirements Overview — Visualize and quality-check all primary EVS data file formats (PGF, GEO, GMF, APDV, AIDV) before modeling. Build simple applications to inspect boring logs, geologic surfaces, and analyte data.
Packaging Data into Applications — Embed data files directly into EVS applications for portability and single-file distribution. Covers packaging individual files, bulk packaging, reading packaged files in new modules, and special handling for multi-file formats.
Geostatistics Overview — Understand the statistical foundations of kriging-based volumetric modeling. Covers standard deviation, confidence, uncertainty, and min/max plume estimates — the tools for defending site characterization and guiding sampling strategy.
Video Training
