I'm here because I work in GIS, and I've used Thiessen Polygons to create territories. I wanted to understand the math behind it, and this couldn't have been a simpler and more comprehensive video to show just that. Thanks!
This is amazing. Thanks a lot for the video.
Do everyone come here for their Hydrology class?😂
thank you brother.
Thanks
I remember watching this video back in high school five years ago for an ArcGIS project. Now five years later you've saved me again as I attempt to draw Thiessen Polygons for my junior level college hydrology class. Thank you twice for this video
why so lag
I had a really bad document camera.
Is video in 4 fps?
please for example
So good Thanks a lot!!!! <3 do you got a video to the Grid method^^?
Well explained!
Thanks a lot sir
Can you also create a tutorial video for Isoyetal analysis method? Thanks! Great video by the way!
Thanks for the reply. Unfortunately I'm not familiar with that method. I actually just made this video to talk about calculating rainfall using some basic statistics.
so beneficial. thank you for make this video ...
This video cuts NEAT like a scalpel. Thank you.
Thanks for making these video. Because of you I can understand the concept of these methods. I am thankful to you 🤗
Perfect mate👍👍......
Useful
Why teachers at university can't teach us like people in TH-cam!!!!!!!!!! I got the whole subject in 10 min video
Helped in my civil services optional geography preperation....Thanx a lot for explaining this concept in a very easy way☺
how do I use the grid method to calculate?
Just overlay any grid onto the picture and count the squares in each area. It sounds really approximate but gives surprisingly consistent results. I did it with a class of 30, and almost everyone got within about 1% of each other.
@@trevorray831 thanks I appreciate it 😍

thats-perfect
Helpful
how to solve area?
It doesn’t sound very scientific, but the easiest way is to put a grid on top of the picture and just count the number of boxes. Because everything is an approximation anyway, it works quite well. I had a class of 25 students try it, and almost all answers were within about 2% of each other. The smaller the boxes in the grid, the more accurate the results will be.
This was very helpful. I was struggling with how to do this but you made it a lot easier to digest and understand. Thank you!
Thank you From Iraq 🇮🇶 ♥
What if we connected D and C, instead of B and E?
Thank you
What if there is no point e.
Then the lines between B & D and B & C get extended downwards until they meet, and you have to another perpendicular bisector between D & C.
Please help me with a doubt, all the triangules must contain the point where coverges their mediatrixes? I have problems with harder problems where there are more triangules.
Nice..
Thank you so much!
why aren't a and c connected?
Congrats sir, your videos have been used in my hydrology class
Thanks a lot .now there are no more worries about Thessian polygan theory
PANCEN CELENG
Much better than my useless teacher, Thank u
Very straightforward and clear video, thank you :)
aap ne hote to kya hota
Sweet!
thanks
very helpful tyty
Damn, english is not my first language but still I can understand you way better than my actual brazilian teacher
Me too hahaha
I peed my pants
Me too bro
Simple and nice
thank u..
so clear, thank u
Y is the video lagging
How this method is useful to find out buffer zone around each primary health center and community health center. Plz explain it
