Step 1: Load Geological Data

To get started in Vulcan GeologyCore, you will need to bring some data in. When you load data into Vulcan GeologyCore, a local copy is created and stored in your projectClosedA Vulcan GeologyCore project is a local store of your data. A project is stored physically on disk in a database folder with a .maptekdb extension. Most data that you load into Vulcan GeologyCore is imported as a copy, although some data can be imported as a live link back to the source file(s).. This local copy acts like a snapshot of the data that you can modify without changing the source data. The local copy also helps to ensure consistency during the modelling process as you test different scenarios. As new data becomes available, your geological model can be updated without having to set up any of the process again. When the model is completed, you can publish the data back to the source database.

Loading data for geological modelling

Drillholes are the main data source for generating geological models. You can load drillhole information into Vulcan GeologyCore from a variety of sources, including:

  • Vulcan Isis drillhole databases (*.isis)

  • Vulcan ODBC link drillhole databases (*.dsf)

  • Comma-separated values (CSV) files (*.csv)

You can also load other data, including:

  • Legends—for colouring drillholes or block models by attribute.

  • Composites—which can be used to generate an implicit or DomainMCF model. If your drillholes already have domains defined and composites created, you can go straight to Step 4: Generate a Model.

  • Triangulations—which can be used to limit the scope of your geological model, help define your domains, or to aid in manual interpretation.

  • Design Data—for comparing to your geological model or preparing limits for your drillhole data. Design data has the file extension dgd.isis. Design data can also be used as interpretive data when implicit modelling.

  • Block Model Definitions—for defining model extents when generating a geological model with the Modelling Manager or DomainMCF modelling.

These key data types used in geological modelling can be efficiently loaded into Vulcan GeologyCore at any time using the Load Vulcan Data tool, located in the Data group on the Home, Modelling, DomainMCF and Stratigraphic ribbon tabs. The tool automatically detects relevant data in your Vulcan project folder.

Follow these steps to load geological data into Vulcan GeologyCore using the Load Vulcan Data tool:

  1. Launch the Load Vulcan Data tool and select the files to import.

    1. Click  Load Vulcan Data on the ribbon.

      The Load Vulcan Data panel appears.

      Relevant files found in the data folder are automatically listed in each file type section.

    2. Select the files you wish to import.

      • Click on a file to remove it from the list of files to import.

      • Click on any list to clear all files from the list.

      • Click to the right of any Files field to browse for files to import. Browsing and selecting new files will replace the current file selection.

      • You can also import other data types not listed in the Load Vulcan Data tool from the Home > Data > Import ribbon menu item. For example, Open Pit blastholes (including multi-interval blastholes) can be loaded into an internal drillhole database from a single collar CSV file.

  2. Import selected files.

    To import selected files, do one of the following:

    • Click Import n files (e.g. “Import 2 files”) in any given file type section to import only the files listed in that section.

    • Click Import All to import all files listed on the panel.

  3. Confirm drillhole database import.

    If you chose to import a drillhole database, a panel appears where you can configure and confirm the import.

    1. Configure the database import settings.

      It is recommended to use the default import settings. You can, however, modify the import settings.

      Tip:  Be sure to select the Internal database radio button if you want to use the Domain Manager to dynamically code domains.

    2. Click OK to import the data.

      The data is imported, and by default is stored in various standard containers within your project.

      If you selected the Display imported data in the view checkbox on the import panel, the imported data will be displayed in a view window.

      When import is complete, Vulcan GeologyCore automatically performs some consistency checks on the drillhole database, which you can inspect in the report window.

      The report is also saved to a CSV file in your data folder.

      • To view the CSV file in the Workbench CSV Editor, drag the file from the report window onto the Workbench Start Page tab.

      • To show the CSV file in a Windows file browser, simply click on the CSV file in the report window .

      Selection files

      Note:  This section is a work in progress and will be updated shortly.

      The Vulcan selection files (.sel) can be imported, created, edited, and stored in Vulcan GeologyCore. Internally, they may be classified as Inclusion and Exclusion lists.

       

      In Step 2 of the Vulcan GeologyCore Workflow, you’ll learn how to fix any problems detected.
