Structure of dBASE Format of ILG Database
The Structure of the ILG Database: F-Format (dBASE)
Effective from February 27th 2011 after last changes in December 1999 and February 2008 (subject to change).
ILG data entries and information are based on old and current monitoring experiences made over the last 40 years...
F-Format ILG is designed for monitoring & bandscan analysis, various deep-in statistics, station, language, ... research
Exclusive ILG data fields are NA,CA,SA,EU,AF,ME,AS,AU,PA since 1989 and the usage is exclusively
only allowed to use by ILG Database and not by any other software
