Spécifications

  • Each species in the database is identified by unique OMNIDIA four letters codes.
  • Print customisable detailed reports per inventory.
    Example
  • Print up to 12 inventories in a comparative report, including indices results and species lists.
    Example
    (data source: DREAL Languedoc-Roussillon-Midi Pyrénées)
  • Internet updater for species database and references.
  • Export OMNIDIA results to Microsoft Excel files (XLS) or tabular text files.
  • Built-in backup and restore utility.
  • Import and export inventories using XML format (OMNIDIA 6) or PRN (OMNIDIA 5 compatible).
  • Import files in user defined formats for inventories using customised tabular text.
  • Connect multiple OMNIDIA clients to a network database, using free and optional HFSQL server interface (for Microsoft Windows).

New in OMNIDIA 6.1 :

  • Users can edit each diatom indices values and add new species to the database.
  • Keyboard counting function: users can program keys for fast counting.
