ABSTRACT
Sugarcane is one of the most important and major harvested crops in Bangladesh. In this study, a rapid mapping of sugarcane harvested area and its crop growth condition was extracted using a Landsat imagery of 2014. Land use and sugarcane growth condition maps were created using supervised image procedure and Normalized Difference Vegetation Index (NDVI) respectively. The resultant landuse map shows about 75% area was covered by agriculture of which 20% was sugarcane. In sugarcane cultivation areas, about 43% and 45% areas were found as very good to good and moderately good respectively in terms of growth conditions. Moreover, a strong correlation was found between the Landsat extracted areas and field data (R2= 99%). The overall accuracy of the landuse and sugarcane growth condition was 95% and 97% respectively.
