Development of a method to estimate the distribution of agricultural land use based on satellite data in the central part of the Deccan plateau in India
Vegetation index calculated from satellite remote sensing data rereals specific patterns of seasonal changes depending on land use types. In the semi-arid area of India, the value of the vegetation index of agricultural land use could be differentiated from that of other land uses during the latter half of the post-rainy cropping season called Rabi. In this study a method to estimate the spatial distribution of agricultural land use by adapting the temporally variable threshold value of vegetation index was developed. This method has enabled to collect quantitative information on Rabi cropped area for several years with available satellite data. Investigations of temporal changes showed that the location of the cropped area was correlated with the amount of rainfall during the sowing period and with the suitability of land conditions.
