Crop acreage estimation is important for advanced planning and taking various policy decisions. The present study was carried out in Indore district using AWiFS sensor satellite data from sowing to maturity period as well as single date LISS-III sensor satellite data of maximum vegetation growth stage of wheat crop. The technique used for single date LISS-III data classification is complete enumeration approach based on supervised classification. While Multi-date AWiFS data classification technique is based on two-stage classification of multi-date dataset by unsupervised Iterative Self Organizing Data Analysis Technique (ISODATA). The acreage estimated using the LISS- III sensor data is 98.41 000’ha while using AWiFS sensor data is 105.70 000’ha. It was found that LISS – III results shows -6.89 percent underestimation as compared to AWiFS estimates. The comparison of both (LISS-III and AWiFS) sensor’s acreage estimates with the actual acreage data (viz. 97.20 000’ha) shows that higher spatial resolution (LISS-III) sensor satellite data have more accuracy than low spatial resolution (AWiFS) sensor.
