The project of digitizing the decametric data recorded on 35-mm films rose from from the inventory of the decametric archives (Lamy et al., 2017; Cecconi et al., 2018).

The refurbishment of the data archive was organized along several steps detailed in this section :
 Definition of technical requirements and selection of a specialized digitization company
 Test and scientific validation of the digitized data
 Final archiving of the digitized films
 Digitization of observation logs stored on paper sheets
 Digitization of published catalogs of Jovian radio emissions
