As discussed in Annex 1, LRIT data was processed in a way consistent with AIS sources. LRIT as a data source
is discussed in more detail in the following section on temporal coverage. Comparing LRIT with AIS coverage,
it is immediately apparent that the coverage is adequate for LRIT in the North Atlantic and Indian Ocean but
poor in the Pacific. For the most part, it is suitable as a corroborating data set for coastal regions. The major
areas of traffic highlighted by LRIT are the European sea area, the Far East (Singapore, China, Japan and the
Republic of Korea) and the shipping lane connecting them. These areas and routes are well covered in AIS
from 2010. There are no regions identified by LRIT that are not covered adequately by the 2010 to 2012 data
sets.
