dc.description.abstractThe study was aimed to learn the techniques for crop production forecasting, using single date LISS-III data and multi date A WiFS data for Vidisha District, Madhya Pradesh, India. The techniques in complete enumeration approach for single date LISS-III is based on supervised classification of multi-date dataset by unsupervised Iterative Self Organizing Data Analysis Technique (ISODATA), labeling of classes based on temporal spectral profiles of wheat, mustard and other competing crops, discrimination of non crop classes by decision rule classifier and decision rule based integration of final classified image. This hybrid classification technique takes advantage of inherent clustering tendency of land use / land cover classes in feature space with temporal dimension added to it in terms of NDVI time series data and it also makes use of signatures of known crop classes for labeling the clusters. A common approach of sample segment includes random stratification of study area, extraction of strata, training site generation followed by supervised classification. Comparative analysis of two types of approaches shows the estimated acreage 194.1 (000’ ha) by complete enumeration approach and 198.1 (000’ ha) from sample segment approach. The acreage estimates using sample segment approach is 1.89 percent more as compared to complete enumeration acreage estimates for LISS-III data. Using A WiFS data the acreage estimates is 203.7 (000’ ha) in the complete enumeration approach and 206.89 (000’ ha) in sample segment approach. Here also it is found that the estimates using sample segment approach is 1.56 percent more as compared to complete enumeration. This comparison shows that the results estimated through sample segment as well as complete enumeration are not having significant difference. Comparing the acreage estimation result of A WiFS data shows 4.77 percent over estimation than LISS–III data. Comparing sample segment approaches results of both sensors; it is found that A WiFS results shows 4.43 percent over estimation than LIS-III results. This comparison shows that higher resolution sensor satellite data have more accuracy than low resolution sensor satellite data because in low resolution possibilities of mixed pixels are more than high resolution data. Yield prediction has been done using the time series analysis. The historical crop statistics have been regressed with time to predict wheat crop yield for the season 2010-11 and R2 was found to be 0.67. Predicted yield using trend model is 1773 kg / ha for Vidisha district. Production was also estimated using Acreage and yield estimates.
