I want to extracting slope (%) for my river and for that reason, I use the Profile Tool. However, I have an issue with the measurement unit of X axis when plotting the longitudinal profile. It is not in meters. I don't why this happen. What I have done are: 1. I convert the projection of DEM from EPSG 4326 to certain UTM zone (in this case, EPSG 32749 - WGS 84 /UTM Zone 49S) 2. I also convert the projection of the river polyline layer to EPSG 32749 - WGS 84 /UTM Zone 49S as well. What should I do to fix this issue? I use QGIS 3.28.9 Firenze
For some reason horizontal distance on the profile is wrong in my case. It's 1.6 times bigger than it actually is, kinda like it's trying to convert from miles to km, although I have meters in project settings. Any help?
Great 👍 I am thinking that this technique could also be used to get cross sectional profile of other data, such as regional temperature, precipitation, etc?
You cannot even imagine how much I appreciate you and your videos.. I even dont do my searches on RU-vid, I directly search your channel for QGIS and ArcGIS. You are an excellent teacher. Best of luck to you.
@@geodeltalabs first of all, thanks a lot for your videos. I really appreciate your work. Amazing To be specific, in drastic model we have R, net recharge, so if you can please make a video on that. How to make a net recharge map. Would be great if you can make videos on all the parameters of the drastic because there are no good videos on RU-vid about that
That was great tutorial thanks. Is there a way to do same sort of procedure in netcdf data using x axis as level (eg pressure) and y axis as time, as we do in ncview tool
Fantastic...... You saved me from relying on this option on Google Earth☺. Now I can extract and present what I want to reconstructed from the DEMs. Thanks a lot.
Thanks a lot for the great video. Very clear and easy to understand. I got the reliable results using terrian data downloaded by SRTM downloader, but when I used another DEM(.tif) that I already downloaed, the results are different. Horizontal profile is the same, but the elevations are different. May I know why, please?
Hi, great video! Could you please also show how to generate the selected region's mean, maximum and minimum topography profile? It's pretty common in scientific papers, but I still don't know how to develop it. Thank you!
