This paper described a digital convolution enhancement procedure for interactive extraction of linear features from remote sensing image. It consists six steps: （1） Preprocessing the image. （2） Directional convolution filling for edge enhancement. （3） Smoothing and noise reduction. （4） Interactive extraction of linear features. （5） Producing a all direction lineament map. （6） Overlapping the lineaments onto the original image. Those images obtained using this procedure provide useful tools for further analysis and geologic interpretation of the lineaments.The lineaments extrated from MSS image in Mongshan region of Shantong province and in Tongling area of Anhuei province are taken for two examples to illustrate the effect of this method.
