Land Cover Change

Knowing that something changed is rarely the question. The question is what it became: how many hectares of forest became pasture, how much farmland was built on, where wetland was drained. This service produces that answer as a transition matrix — every from-class to to-class pair, with its area and its location.

It works by classifying two epochs consistently and then comparing them, rather than by differencing images directly, which is what prevents seasonal appearance from masquerading as land use change.

Because the same method runs over any pair of dates, it serves both directions of a typical request: the retrospective study that establishes what has happened over a decade, and the recurring report that says what changed since the last one.
