In this paper we are mainly going to adopt the spectral mixture modelling in order to produce the land cover maps in the study area which covers the Tumkur district,Karnataka.SpectralMixture Analysis (SMA) whose results are compared with the Ground truth data.SMA was performed and evaluated based on Landsat-8 ETM(Enhanced Thematic Mapper Plus) data. Landsat-8 ETMwas available at 30 m resolution with six spectral bands (excluding the panchromatic band and thermal band).The Landsat-8 ETM scene used in the study was acquired on March 2014.The image was prepossessed and resampled at 25m resolution.SMA can be achieved by using the Digital Number values and the corresponding radiance values, which will be available along with the satellite image. The accuracy of the classification result can be obtained by taking the absolute difference between actual and modeled estimations.
