DEF

[The] analysis of remote sensing data obtained from the same area, but at different times.

CONT

In relation to the use of satelital imagery in 1998, we carried out a test on a methodology developed by the Finnish Forest Institute, using Landsat imagery and multitemporal analysis to update about 35.000 Km² of the 10th region (the Lakes-region), giving moderate quality results, mainly due to problems to get good images of the dates required.

OBS

multi-temporal analysis: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Engins spatiaux
  • Télédétection
DEF

Analyse de données de télédétection obtenues d'une même région, à des moments différents.

CONT

Enfin et plus généralement, la classification décrit l'état de la zone à la date d'acquisition de l'image et ne saurait décrire l'assolement cultural ou l'occupation du sol à l'échelle d'une campagne; en effet, les thèmes agricoles présents (cultures irriguées, maraîchage) impliquent une variabilité intra-annuelle forte et il conviendrait d'effectuer une analyse multitemporelle pour permettre ce genre d'analyse.

OBS

analyse multitemporelle : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).
