| Abstract/Description: | Rice is an important cereal crop in India and adaptable in various types of land management systems. Recent advancement in the field of remote sensing and GIS has opened up new challenges for various thematic applications towards efficient resource management. The present study was aimed to estimate the area under rice at mandal (block) level. Using a combination of Normalised Difference Vegetation Index (NDVI) and unsupervised method to estimate area under rice can reduce processing time and reinforcing the performances of both classifiers. IRS 1D LISS III data was used and five major rice growing mandals (blocks) of Nalgonda district of Andhra Pradesh were selected for this study. One model was developed to zero non-vegetative features in the original image by using NDVI of image. This image was further classified by unsupervised classification and results were in agreement with reported values. The study reveals that the combination method of NDVI and unsupervised classification appears to be the better choice for estimating area under rice. |
