Prior to being able to use an image in a landuse classification exercise one must first make fundamental corrections to the image data . the level of corrections differs for each satellite sensor but will generally involve sensor calibration for radiometric correction ( sun angles , earth - sun distances and atmospheric scattering effects ) , geometric corrections and geo - referencing to a known coordinate system 在将图像用于土地利用分类处理之前,必须首先对图像资料进行基本修正。对于不同的卫星感测器需采用不同的修正参数和方法,但一般涉及感测器校正,包括辐射校正(太阳角度角、地球与太阳的距离和大气层的散射效应) 、几何校正以及设制地理座标。
