Among them, one of the most applied segmentation techniques is the region growing algorithm. Within this context, this paper describes a study case for a multitemporal segmentation that adapts the traditional region growing technique. Our method aims to detect homogeneous regions in space and time observing a sequence of optical remote sensing images. Tests were conducted by considering the Dynamic Time Warping distance as the homogeneity criterion to grow regions. A case study on high temporal resolution for sequences of Landsat-8 vegetation indices products provided satisfactory outputs.  aSensoriamento remoto  aSistema de informação geográfica  aDynamic Time Warping  aProcessamento de imagem  aSegmentação multitemporal1 aFONSECA, L.1 aKÖRTING, T.1 aSIMÕES, M.1 aKUCHLER, P.
