when you do the ndvi do you need to save it within the folder of the Sentinel data e.g., the one starting with S2B_MSI etc.,? Whenever I do the NDVI calculation it never comes up with -1 to 1 as the limits - always random numbers in between this. Do you know why this might be please?

Hi, does this method only work for Sentinel 2 L1C data or does it also work for L2A? I have very differing results (some working, some anomalous) and I am wondering if it is because I used Sentinel L2A?

Thank you Hans very helpful for my projects in Vanuatu

Thank YOU!! from Down Under.

Past photos, and past videos ¡ ... ahea ¡

Salutations, Hans I installed the pcaster properly by following the instructions, but why isn't it visible in the QGIS environment with version 3.34 to be a plugin?

I watched this tutorial during my final year at varsity in 2019 for a design project we had. 5 years later and I return to this tutorial for a big project in Africa. Hans, thanks for this brilliant and elaborate video, appreciate it dearly.

Amazing tutorial, I try to ad the scene for Amsterdam but I don't get the layer when I add it, I try to change the coordinate system but still not showing the layer. What might be the reasons?

Could you provide details of stream and catchment Delineation for flat area?

Sir there is some problem regarding upslope area. What should I do?

Thank you very much

do you have a link from which you download that data

Donde puedo descargarme los datos de vi3nto?

Impresionante video, se te agradece bastante.

Thank you! :)

Can we make a video with the SRTM as DEM please?

Thanks a lot. This Video helps me to find my way👍

Thank you sir...any way to estimate water budget of a region sir

My volume and area units are degree square and cube.. how can i change it into meters

is it possible that their areas will also be intersected so i can know the area of that specific landcover in each subbasin? thank you!

How could you export the raster layers to a merge single netcdf file to share?

Thank you very much, you are a teacher for me.

I want to do this in Asia. Specifically in the Mekong Delta of Vietnam. Currently, the delta is facing climate change, rising sea levels and flooding in urban areas. I really like this video, can you help me analyze flooding like this in Asia?

Is this possible in QGIS 3.36.3 for Mac? Could you please advise how to proceed? I don't see the Point Cloud Conversion Tool in the tool menu.. Thank you.

Hi Hans, I have downloaded the latest release and the table is now editable. However, when I drag in the flowdirmesh file it appears in my layers, but not as yellow on the screen. I also can't see the arrows when I change to that. Do you have any suggestions as to what the problem could be? Many thanks.

must clip the sea area?

Thanks for this tutorial. Don´t you know how to Tile pointcloud and name it according to atribute of clipping/tiling polygon?

Hello, I'm having some issues using the 'upslope area' tool. I'm using QGIS 3.28.11 and have gotten the error " SAGA version 7.8.2 is not officially supported - algorithms may encounter issues". Is there another way for me to delineate the catchment using a different tool? Thank you for all of your helpful content

First of all thanks very much for this amazing tutorial. I want to do the same analysis for an area in Germany, but I could not find DTM and DSM with higher resolution than 30m. Would this type of analysis work with such resolutions?

Que interesante. Se puede exportar el video???😊

Hello. I am trying to do something similar to this but with many more points (about 5000). Memory-wise, it is not feasible to load each layer and merge into one file. All I need is the resulting attribute table with costs and ideally distances of all the paths. I can save each path as individual files without loading them, but I was wondering if you have further suggestions on how to approach this issue.

Hi Hans, when I create a new attribute table, it is not editable. How can I solve this?

When I use the raster calculator in the model designer it always shows seven layers named A, B, C, D, E, F, G. But not the actual layers like shown on your video. Why does it do this? A works in the calculations, but only if it is the only raster input in that line of algorithms. How do I get it to show the correct raster layers in the raster calculator?

Great help for learner, thank you sir

How to download point of interest ? and how to handle data

Hello, thank you for all your videos they have been a great help. My first hurdle is my Raster attribute table has the edit toggle greyed out. I also am getting an error when trying to us the Lookup tool, resulting in no excel sheet produced. Do you have any solutions? thank you

Thank you

Please Professor, how do we calculate knickpoints from a DEM during drainage or stream analysis? Thank you

Thank you for putting all this together for us. Let God continue to empower you. Please can someone help me with a link to generate 'knickpoints' in stream analysis ?

Why can’t I set a non-integer level elevation value in the raster calculator? For example, a request less than 1 meter is possible, but less than 1.3 is not possible. and how to solve this problem

Concerning geopackage, is it possible to create and stores relations 1/N? I was able to do it in filegeodatabase, but would prefer with geopackage. Thanks

Hi Hans, is it perhaps possible to use plugins from a new version 3.32 into an older version (mine is now 3.28) ? It always takes me so much time download & customize a new version and then re-install the plugins and add them to my toolbars New versions come out very often and I don't want to keep re-installing QGIS and go through the same process I would like to use the point cloud conversion plugins (from 3.32) as per your example but I don't know if that is easily done? I suspect there is an easier way to download a new version of QGIS and still be able to keep all toolbars and settings, perhaps an idea for a video ? Thanks for your great videos

it takes 2 minutes to make a map....and one weak to solve all the errors this program gives!!

Hey Hans, I have a bit of a video request, would you be able to show us how to do a dam-break model in HEC-RAS using QGIS for the topography files and such. Would be awesome if somebody finally explained in plain clear english what needs to be done! - Isaac

Hi . Thank you for sharing this amazing information . Im new to WebODM . I wanna buy the software . And Im not sure if its going to work offline without internet ! Somtime I travel for long distances fo remote area . And I dont have any link . Is this software can works also by offline situations?

A lot of time wasted seen tons of other explanations.... this is THE REAL THING !! best.... thanks...!!

how it is possible to add some country in WEB tab? I saw that you have Georgia country, how can I use?

Lo hice y quedó perfecto, solo que tuve un inconveniente con relacion a el paso de (spatial), lo arreglé no guardando la capa temporal, al igual con la herramienta accuflux, tambien le puse una simbología de 1000 y quedó perfecta. Muchas gracias maestro!! :) saludos desde Guatemala.

Excuse me can I know what is the name of the algorithm used in this tutorial, please?

Great tutorial, ty so much!
