The term Analysis of the remote sensing data is faced with a number “Signature” is defined as any set of observable of challenges ranging from type of sensors, number of characteristics, which directly or indirectly leads to sensors, spectral responses of satellite sensors, resolutions the identification of an object and/or its condition. in different domains and qualitative and quantitative interpretation. Any analysis of satellite imagery directly Signatures are statistical in nature with a certain depends on the uniqueness of above features. The mean value and some dispersion around it. Spectral multispectral image from IRS LISS-III sensor has been variations: Spectral variations are the changes in the used as the primary data to produce land cover reflectance or emittance of objects as a function of classification. This paper reports on the study of LISS III wavelength. Spatial variations: Spatial arrangements image, with emphasis on spectral responses of satellite of terrain features, providing attributes such as shape, sensors.
