Estimation of summer paddy in Haryana (India) using high resolution satellite data

Multi-date LISS-III data from Resourcesat for the period April to June, 2006 and single date LISS-IV sensor data of mid May, wherever available, was used for area estimation of the crop for the year 2006 for four major districts of Haryana state where majority of summer paddy is grown. For area estimation for the year 2000, only multi-date LISS-III data was used. Hybrid approach of supervised and unsupervised classification was used for discrimination of minor crops in LISS-IV data. Multi-date LISS-III data based crop profile helped in precise location of training sites for LISS-IV data. To improve accuracy the non- agricultural areas like settlements, wastelands, forest etc. were masked out by using non-agricultural mask. Study indicated that an area of 39,800 ha was under summer paddy in the year 2000 which has been reduced to 1250 ha in the year 2006 in all the four districts. The district wise area for Fatehabad, Kaithal, Kurukshetra and Karnal was 4981, 3228, 9118 and 22475 ha for the year 2000 and 383, 197, 176 and 493 ha for the year 2006, respectively. District-wise crop maps of summer paddy, showing extent & distribution of the crop, were also prepared in ARC/GIS.
