hello, fantastic job on making this concise and precise video. But i'm stuck with upslope area as error is popping up "tool needs graphical user interface [Upslope Area]"....what to do?

@lychang4kimo1 2 года назад

02:04 Fill sinks (by Fill Sinks - Wang & Liu). Make tolerance to be zero. 02:41 Get Stream order (by Strahler Order). 03:31 Extract streams above specific order (by Raster Calculator or Layer Styling Tool). 04:36 Get coordinates of interested river outlet to retrieve corresponding watershed. 05:02 Get watershed area (by Upslope area)

i have problem with getting upslope area , all steps have done properly except the watershed that keep showing an error about layers and still i couldn't fix it

@@muhammadbagusharisantoso2884 hopefully i fixed it , you need to go (Payton>definitions ≥upslope area> then open the note pad and enter |4 front of upslope area . ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-t-2ExoyhIfA.html Here you can find the exact instruction.

Hi, great video. Please could explain the use of GRASS tools (r.lake; r.volume and r.surf.area)

@shermanfrancis440 4 года назад

Great video. Thanks so much for sharing.

@GeoGuru1 4 года назад

You are so welcome!

@communistinternational1431 2 года назад

We can do the lat long part by creating a point shp file also right?

@rafiaanjumrimi5015 3 года назад

when I am doing reprojection, "the following layers are not correctly generated" is showing. how can I solve the problem

@remimayou1867 2 года назад

Thank you very much Geo Guru, this tutorial is very helpul ! Right now, I'm looking for explanations about the different operations (Fill Sink, Strahler Order,...) and how they work and produce a result. If you have references, do you mind sharing them ?

What is the use of finding ground water areas using gis software What is the output finally what we are going to conclude

@majesticchicken8992 Год назад

i can’t find the reprojection option under the raster. and when I’m searching for it, its also not showing up. please help!

SAGA version 7.8.2 is not officially supported - algorithms may encounter issues. IM USING 3.26. can u help me>

@stef065 4 года назад

Interesting tutorial, also if I'm not able to obtain any valid result from 'Upslope area' tool.

@udigiripraveen6656 2 года назад

In the last step It is showing that the layers were not generated correctly and upslope area layer is not created.. how to solve this issue sir.

@TonyGokuSS4 3 года назад

Very compliments for this video. It is really a simple and performing solution. However, is there a method to pass a shp with multiple points to the upslope function and retrieve a polygon for each of them? Thanks.

@GeoGuru1 3 года назад

It can be possible using python or model builder, but not with conventional way.

@GeoGuru1 2 года назад

There is a problem in the newer version. If possible try to use the older version (3.10)

@guvenbasrialrsatar4417 4 года назад

I had to stop several times, because procesess were not clear at all, I did all of S/he did but I couldnt find the resluts, because there is limited explaniation, I think this is not useful at all.
