OMNIDIA Software helps diatoms researchers to manage their diatoms inventories derived from water samples and to calculate diatoms indices.

OMNIDIA’s database includes:

  • More than 28 000 diatom species and synonyms, with 920 Genus (updated once a year).
  • 7000 references to publications.

For each diatoms inventory, OMNIDA calculates:

  • 25 diatoms indices
  • 38 ecological statistics

OMNIDIA was originally developed for French water agencies and IRSTEA to help them manage diatoms inventories database and calculate water quality indices. It is now used in more than 50 countries and has become a key reference for diatoms research projects.

OMNIDIA data is collected by Michel COSTE, Director of Research at IRSTEA Bordeaux, France.
