1D FFT

The 1D FFT tools offer a suite of filters and statistical tools designed for processing large volumes of geophysical data. Spatial 1D filters allow field geophysicists to apply a variety of linear and nonlinear space domain filters, enabling efficient data enhancement and analysis. The tools support the application of a broad range of Fourier-domain filters to one-dimensional (line-based) potential field and other geophysical data, allowing for effective data processing and interpretation.

Open a New Project

Working in Oasis montaj requires a project file (*.gpf). A project encompasses all items in your workspace, including:

  • Data files (for example, databases, grids, maps, voxels, geosurfaces, and 3D views)

  • Visualization tools such as histograms and scatter plots

  • Project settings, including the menus currently displayed

This structure ensures that your working environment is saved and can be easily restored.

To begin working with an extension, open a new project and then load the corresponding menus.

  1. On the Project menu, click New. The New Project dialog opens.

    Alternatively, select Create new project from the startup dialog when you launch Oasis montaj.

  2. In the New Project dialog, specify the name and location for your project file (*.gpf), then click Save.

  3. The new project opens, enabling the main menus, toolbar icons, and the Project Explorer. These visual indicators confirm that the system is ready for use.

Load the Menus

  1. On the Project menu, select Manage Menus, or click the Manage Menus icon on the Project Explorer toolbar. The Manage Menus dialog opens.

  2. In Base Menus, expand the Processing node, select 1D FFT under Filtering Tools, and click OK. The related menus will now appear on the main menu bar.

The menu system is designed to provide quick access to a variety of tools and guide you through the primary processing and filtering workflows.

To automatically load these menus in future projects, specify them in the Default menus field of the General Settings dialog.

Accessing Help

Once the 1D FFT menus are loaded, click the Help button in any dialog opened from these menu items:

  • The reference topic for the current dialog will be displayed.

  • Use the Help Topics tab to navigate to other topics of interest.

  • Use the Search tab to find specific topics by entering keywords.
