This videos describes how a digital elevation model can be corrected and how to use some geoprocessing tools to create other hydrology datasets like flow direction, flow accumulation and stream network. Enjoy!
2:19 You can use the math tool and subtract the DEM’s , zero value means no sink 4:55 if zoom out and click the last pixel you’ll see the value is close to 60813
Thank you for demonstrating it, really helpful. I want to ask something, can't I use Stream Order tool instead to create river order? What is the difference between stream network and stream/river order? Thank you
Hello I have a question when, for example, I want to digitize a property map for my employer. How do I prepare the scan and do I need more data? I'm supposed to name two datasets and their geometry type that you can derive from the scan.
