Application of Remote Sensing and Geographic Information System (GIS) Techniques for Monitoring of Boro Rice Area Expansion in Bangladesh

摘要: Information on existing food growing area and crop yield how they are changed over the period of time prerequisite for proper security planning management. In Bangladesh, Boro rice (winter rice) plays a vital role in maintaining country. present study, multitemporal NOAA-AVHRR 1.1 km resolution digital satellite data have been used to study extension Bangladesh during 1989 1999. Study amplitude pattern NOAA- AVHRR derived Normalized Difference Vegetation Index (NDVI) relation phenology growth shows that both NDVI sensitive condition type. Pixel based analysis has performed using linear transformation technique. Arc/Info GIS obtain statistics. The supplemented by historical yield, rainfall, ground water level irrigation. Spatio-temporal series significant increase areas country period. Due more profit less hazard winter season, farmers cultivating this replacing traditional varieties. Such an eventually associates utilization addition other sources It is found literature such exhaustive use resulted gradual decline some places area.
