4.0 DATA USED
Remote sensing data
IRS P6 LISS III data was used to map the wetlands. IRS P6 LISS III provides data in 4 spectral bands; green,
red, Near Infra Red (NIR) and Short wave Infra Red (SWIR), with 23.5 m spatial resolution and 24 day repeat
cycle. The spatial resolution is suitable for 1:50,000 scale mapping. The state of Karnataka is covered in 24
IRS LISS III scene (Figure 5). Two-date data, one acquired during October/November and another during
April/May were used to capture the post-monsoon and pre-monsoon hydrological variability of the wetlands
respectively (Table-2). Figure 6 shows the overview of the part of Karnataka as seen in the LISS III FCC of
post- monsoon pre-monsoon data respectively.
