                         estimation of the waves, stream direction and intern waves 
                         estimation researches with the aid of aerial and radar images are 
                         quite extensive. One of the main object of oceanology studies is 
                         the coral reef barrier due that they are ecological and physical 
                         structures that diminish a big fraction of the swell strength and 
                         also sustain high levels of marine coastal biodiversity. Actual 
                         climate change and global warming are leading to the degradation 
                         of reefs structures; so, surveillance tools for monitoring 
                         changes, degradation or loss of those important structures are 
                         more needed that ever. This study introduces an easy methodology 
                         for the analysis of the waves energy dissipation before and after 
                         they hits the reefs, extracting automatically information about 
                         wave distance, central line and width of their crests from Google 
                         Earth images and Stitch Maps program. Information from the images 
                         is extracted using just digital image processing and plane 
                         geometry tools. Despite the low spectral resolution of this kind 
                         of images, this study demonstrated that they are very useful for 
                         quick analysis of wave behavior and also to analyses its loos of 
                         energy when they collide with the reefs, also permitting to 
                         analyze, in a subjective way, changes in the coral reef.",
