Product versions
This page contains tables with product version numbers for the different OSI SAF
High Latitude products and how they have evolved.
The product version number is changed when a change is introduced in the software
that directly affects the contents of the product. Each product has a separate version
number, and these are different from the software version number which is one unique
number for the whole software.
The version number for the products is on the form X.Y, where X
is increased for major product upgrades, and Y is increased for minor upgrades.
Examples of major upgrades:
Introduction of new satellite types not already in use.
Major alteration of product algorithms.
Changing product areas.
Major change in product file formats.
Examples of minor upgrades:
Adjustments of product algorithms.
Introduction of additional satellites from satellite programs already in use.
Adjustments in product file formats.
Adjustments in auxiliary input data.
