Mam u told that D8 algorithm directs water to flow in steepest slope and after calculating slope u told that i will go in 50-40 (least slope). if these numbers are elevation data. either u have done some mistake or missed something
There is a big mistake in the flow direction determination. The direction of flow is determined by the direction of steepest descent, or maximum drop, from each cell.
In Image statistics nxn matrix is used for demonstrations purpose where n is always an odd number. In this she has taken the minimum i.e 3x3 matrix which equals to 9 cells.
Maam shouldnt the flow be in the direction of the maximum slope? In fact, most of the other videos and papers have taken the flow direction along the maximum value of the slope.
First of all she says that highest elevation is 50 but clearly 60 ia going to be higher... Then she says water flows to steepest slope but steepest would be from 50 to 20....Then even going by her logic from 50 to 40 then how on earth does it flow from 40 to 30... Very confused explanation
Thanks for your video. For the flow direction, 50 to 20 is the steepest right? and 20 can go in 15. Thanks.
Hi thank you for this video. I do not understand why water is not going in the 20 cell. Cheers :)
Thank you for this presentation

she said from steepest slope
steepest slope should be vertical direction isnt it?
Yeah in vertical direction (steepest)
Great video!
Thank you so much for uploading this!
great one so it is helping improve practical knowledge
does the values in the slope map are the value of elevation or the slope?
If its of elevation, then the water should flow from 50 to 20..
nice presentation, I liked it!!
Thanks for your simple enriched
video.
all r correct except for the first one..the direction should be towards the 20
Good one Mam
At 7:50, why would the water move to the direction of least slope? Is that an error?
Thank you very much

Thank you so much
can you practically show how to use voxler for hydrological modeling
One doubt, if more than one cell then how flow direction measure.
It would be better if you demonstrated a sample modelling procedure in ArcGIS on this video.
Hello madam can you explain why you divide 9 boxes while discussing the flow direction
In Image statistics nxn matrix is used for demonstrations purpose where n is always an odd number. In this she has taken the minimum i.e 3x3 matrix which equals to 9 cells.
Thank you so much mam, Kindly send the relevant paper which help to carry out this study.
Small mistakes but very informative. Thanks
What is the step for sink condition? When grid is
Thanks
Hello
I have a question and was the principle of generalization. Which processes can be distinguished?
Nice video
please make a video on how to work on glaciers using LS 8 data
Maam shouldnt the flow be in the direction of the maximum slope? In fact, most of the other videos and papers have taken the flow direction along the maximum value of the slope.
are u guys expert
gis
yeah flow will be in the maximum slope direction
1st Thanks.
how to get soft copy your materialrather vidio?
Madam, you said squire of the number but numbers are not eactly squire. Kindly guide
It is not square, it is 2 times the previous value. She made an incorrect statement.
can u share me note of this module please
20 can flow towards 15
