Hi mariane,

The fusion or combination of SAR and optical data is possible to find the change detection due to tsunami, flood, land use/cover change, earth quake, drought, etc. SAR data is giving complementary information to optical data during the disaster time. Various fusion techniques, decomposition techniques and texture based techniques are available for finding change detection. Sentinel-1A SAR data and Sentinel-2A optical image and SNAP software are freely available.

All the best

Hi

go to this link: https://www.sciencedirect.com/science?_ob=ArticleListURL&_method=list&_ArticleListID=-1258564711&_sort=v&_st=17&view=c&_origin=related_art&panel=citeRelatedArt&_mlktType=Journal&md5=4958d9266e80ef2e1e73676c76ae344e&searchtype=a

you'll find a list of articles related to your subject which concern accuracy assessment

Thank you all for your answers. However, what I'm looking for are actual bi-temporal change detection studies focused in land use and land cover change in which SAR data was used to map one date and optical data was used to map the another one, so change detection is done by comparing these classifications (post-classification comparison). I have a feeling that although expected, this type os study is still rare, since so far I found only one study of this kind. So, am I missing some obvious references or are they actually not that usual?

dear you can use these links
