On the example of the inland water bodies of the West coast of the Yamal Peninsula (district Marre-Sale) the error of measurement of their areas according to the shooting from the satellites GeoEye-1 and Landsat 5 has been examined. It has been demonstrated that at the classification of water body on multispectral space images the measurement error of their areas depends substantially on the specified number of classes’ types of the earth’s surface. Empirical equations of dependence of the error from the water body square and spatial resolution of the data satellite imagery have been defined.
