Merci pour l'orientation. mais j'ai besoin d'aide. je me retrouve avec les resultats des pentes de plus de 800% lorsque je lance ma requête sur arcgis. S'il vous plait besoin d'aide.
Perhaps your vertical and horizontal units are not the same. While 800% slopes are possible, they should be very very rare. Make sure your data is either projected into a local coordinate system like UTM or that you're using the new "geodetic" method of calculation.
Hi, I hope you can help me. I am trying to Display the slope in percent rise, but if I run the tool set on percent it just gives the exact same answers or values as degrees. What am I doing wrong?
Hi, Sir. Thank you for your explanation. I actually have a question about curvature value. How do we determined which one is concave convex etc if my value are more then 1000? Because when I search from many source the value are in average range -1 to 1 or -0,05 to 0,05. My DEM coordinate already the same with my location. Is it have something to do with my Z factor? Hope you can help me🙏🏻 Thank you, sir. Regards, Putri
It could well be the Z factor, but also ESRI multiplies the curvature values they calculate by 100x to make the numbers more relatable. webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=How%20Curvature%20works
Hi, I am from Brazil and I am interested in this subject, but your video is unfocused. I want know how you got this results for curvature. Can You explain me how you got it?
There's a table here: blogs.esri.com/esri/arcgis/2007/06/12/setting-the-z-factor-parameter-correctly. As long as you get it pretty close, it'll come out fine.
Neat!!!
THanks Thomas!!!
Amazing content. You saved my Friday!!!
Cheers!!!
HOW IN QGIS? HOW TO DO IT?
Amazing explanation, thank you!!

Sir, it is very helpful tutorial. Sir, my humble request prepare a video on - Terrain Ruggedness Index (TRI) and Vector Ruggedness Measurement (VRM)
Hii, you can tell me literature about curvature? Thank you so much for your tutorial 🙏🏻
This is a fairly technical paper, but it's also quite comprehensive: doi.org/10.1016/j.earscirev.2020.103414

Hi Thomas. If it is WGS_1984, then what Z factor am I supposed to use?
