Structure of Text Format Files of ILG Database
The Structure of the ILG Database: T-Format (Text)
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...
T-Format ILG is designed for HFCC / ITU or FIELDPLOT or WPLOT Software and available in compact ILG format with HFCC extended format
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
