Hello everyone. I have used SRTM 90 m in many of my hydrology projects for creating watershed and so far it has proven its worthiness. But, I haven't had any luck with its newer and high resolution SRTM 30 m prodigy. I have attached an image comparing flow accumulation maps created from both these sources for same location. As can be seen in the image, the flow accumulation model from 90 m is consistent and gives results as opposed to 30m in which there is discontinuity in the flow network. I was wondering if there is some workaround for this situation. Thank you in advance.
