Project Title: Adding Spatio-Temporal Dataset Support to GRASS Data Catalog GUI

Week 9 & 10: Coding Period

Work Done

  • Added all the remaining STDS context menu options discussed with mentors.

  • Added t.*.import options to the Data Catalog toolbar under “Select another import option”.

  • Extended the Data Catalog search functionality to support STDS.

  • Added the following context menu options:

    Mapset node

    • Create temporal datasets

    STDS node

    • Register maps
    • Unregister maps
    • Merge dataset
    • Update metadata
    • Delete dataset only
    • Delete dataset and maps
    • Rename dataset
    • Export dataset
    • Show metadata
    • Display Temporal Extent

    Temporal map node

    • Unregister map
    • Copy
    • Copy name
    • Display layer
    • Show metadata

  • Improved the Data Catalog tree by hiding maps that are already registered in an STDS from the regular map listing. These maps remain accessible from inside the corresponding dataset node.

  • Continued optimizing and improving the main STDS Data Catalog pull request based on mentor feedback.

  • Worked on integrating g.gui.animation into the GUI as a tab. During testing, several performance issues were identified, particularly on macOS, so a separate pull request was created to address them: g.gui.animation: Fix performance issues.

  • Addressed additional feedback and improvements related to the multiple STDS type support in t.list.
