You cannot even imagine how much I appreciate you and your videos.. I even dont do my searches on RUclips, I directly search your channel for QGIS and ArcGIS. You are an excellent teacher. Best of luck to you.
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.
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?
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
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!
@@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 RUclips about that

You are welcome 😊
Thank you! Very useful! cheers from Italy :)
Amazing video! Exactly what I needed

Thanks for the video!
No worries!
Sir very interesting video thanks a lot
You are welcome
I can't have the terrain data downloaded. It shows me the sign of repair data source, why?
Hey please help me , in my new version of Qgis lulc change plugin not show, can you guid me
Is there a way to draw a profile with specific start and end coordinates?
Nice lecture
Useful tool
Hi. Thanks for instruction. Is there a way to save or print out a PDF in a scale? Founded just a png without scale that is not useful
hello sir, greetings to you.
What will be the difference in output data (like this elevation profile), if we do this same task from google earth pro.
Going back to your video on flood animation, how can we do the same but using ArcGIS Pro?
Great 👍

yes, basically any interpolated surfaces can be.
Obrigado
That was great tutorial thanks.

great video. is it possible to show the location points in the elevation profile. Please do make a video on that .Thanks.

What was the other elevation product?
What's the units for the x-axis values on that profile
If you are using a projected coordinate system, typically the distance units are in meters

Hi, the next video will be covering this topic. Stay tuned, it will be published in a couple more days! :)
Hi Could you please tell us how can we save this Profile path as a shapefile?
Once you have the path, you could digitize and create a polyline object, and save it as a shapefile
i dont know if you solved your issue but you can save your line as a dxf which you can then open in autocad or Illustrator
Good
Thanks 🤘
Can you make a video on recharge Map please?
Can you be more specific?
