Mangrove Ecosystem Study of Chakoria Sunderbans at Chittagong with Special Emphasis on Shrimp Ponds by Remote Sensing Techniques

Remote sensing of mangrove biophysical characteristics

“…Previous mangrove remote sensing studies used coarse spatial resolution data: digitized 1:40,000 scale aerial photography (Patterson, 1986;Rehder and Patterson, 1986;Everitt and Judd, 1989), 80 x 80 m Landsat MSS and 30 x 30 m Thematic Mapper data (Butera, 1983;Nayak and Sahai, 1985;Quader et al, 1986), and 20 x 20 m SPOT HRV XS data (Jensen et al, 1991). Patterson (1986) concluded that the spatial resolution of commercial satellite remote sensing data was not adequate to map the narrow fringing mangrove communities in southern Florida.…”

“…Patterson (1986) concluded that the spatial resolution of commercial satellite remote sensing data was not adequate to map the narrow fringing mangrove communities in southern Florida. The benefits of using higher spatial resolution remotely sensed data to identify and characterize mangrove ecosystems were suggested (Rehder and Patterson, 1986;Quader et al, 1986;Everitt and Judd, 1989) but never verified. Therefore, this research examined the statistical relationship between selected mangrove forest biophysical variables and high spatial resolution (2.5 x 2.5 m) multispectral remotely sensed using the following null hypothesis:…”
