Moskis Posted May 12, 2012 Report Share Posted May 12, 2012 Hi, It can be really hard to do, or at least get good results. If you could have lidar data could attempt to follow the methodology mentioned in this paper. http://grslab.yonsei.ac.kr/paper/international/29.pdf Quote Link to comment Share on other sites More sharing options...
mostafa Posted May 12, 2012 Author Report Share Posted May 12, 2012 thanks Moskis, i have not lidar data, lidar data only in specific places of the world, i think that ERDAS Imagine have tool like homomorphic filter, and may be Photoshop do this task.
