Abstract
The advent of remote sensing technology and its potential in the field of agriculture has given new opportunities for improving agricultural statistics. In the present study a suitable methodology is developed for estimating crop area by integrating remote sensing and GIS based spatial sampling approach. An empirical study to estimate the area under wheat crop for district Rohtak, Haryana for the year 1995-96 using IRS-1B, LISS-II data has been conducted. Improved estimators of crop acreage using spatial sampling as suggested by Prachi ( 2002) by using average NDVI of the village as an auxiliary character have been developed. Further, the estimates obtained from this approach are compared with those obtained from usual remote sensing method based on supervised classification. The results of the study show that inclusion of remote sensing parameter in GIS assisted spatial sampling techniques considerably enhance the performance of the estimators.
