IDRISI automates Change Vector Analysis. Given two bands from two different dates, images of change magnitude and change direction are produced. The magnitude image may be thresholded to isolate areas of change versus areas of normal variation while the change direction image may be used to identify the types of change that have occurred (e.g., harvest vs. growth). 4, record 1, English, - change%20vector%20analysis

La végétation dans la Péninsule de Seward, en Alaska, caractérisée par des transitions de la toundra à la forêt boréale, pourrait être sensible aux influences du changement climatique au plan de la modification ou de la composition des espèces. Pour déterminer le potentiel de détection des changements structuraux dans la végétation à l'échelle décadaire, des techniques d'analyse du vecteur de changement (AVC) ont été évaluées pour des images Thematic Mapper (TM) de Landsat de la Péninsule de Seaward de 1986 à 1999. Les scènes ont été corrigées géographiquement à une précision à l'échelle du sous-pixel et ensuite rectifiées radiométriquement. 1, record 1, French, - analyse%20du%20vecteur%20de%20changement
