This tutorial demonstrates to you how to calculate the volume of a specified river cross section using the ArcGIS 3D Analyst tool.
⭐NOTE:
‘Kite’ is an excellent tool that can help you boost your productivity when it comes to programming with its free Artificial Intelligence (AI) powered coding assistant. Kite is a plugin which provides smart completions and documentation as you’re typing-in your code, and its compatible with most of the well-known IDEs such as PyCharm, Spyder and VS Code. I absolutely love it, and recommend you guys to try it out as well.

It's so useful and thank you for creating this video.
Also I have couple of questions and there they are:
1. how did you get the data of surface, did you download a DEM or manually collected coordinates and elevation points?
2. when you've been got data of surface, the data was including river's base or river's mirror?
3. how did you get the date of difference between river's base and river's mirror?
Sir your video tutorial is very special to me. Respect
This is great work, but I have a question about units:
I would assume that the vertical units are whatever is specified in your raster, so they are meters. However, how are the horizontal units measured? Are they raster rows by raster columns? Or are they defined in another place? So if my raster resolution is 1/2 meter by 1/2 meter, while my vertical is in meters, the output volume will actually be in Meters /4.
What are the unit for 2D, 3D areas and volume?
Great Video, It really helpful. So what is the unit of Volume (m3, km3....) and Area (m2, km2). Then the Surface volume based from DEM (unit meters, kilometers..) Thanks!
Hi sir, how did you make the waterline?
You create a polygon using create feature, and you set up that it has elevation attribute (Z). Then after you digitize, you open the attribute table and you insert a long attribute, in your case, height/elevation. When you open Scene, you will select this layer, and then you will select the attribute field for elevation. Then you select the layer position from ground to the raster, in the layer's properties
@@Alex-co5cothank you for the reply sir.
Thank you
You're welcome
very helpful! thanks
Really helpful video, sir. How to make water levels Shape file?
What's the unit of the Volume?
Meter cube
thank you！it's really helpful for me！and i’m wonder how to calculate the surface area？
Great ane easy explanation. Does the volume values come in cubic meteres?
Yes
Can you please make other video for the same episode, with all details, we need to know how do you create that water livel .
You may refer to this video. There I explain how to create the water level
ruclips.net/video/-vam5rtVCP0/видео.html
@@geodeltalabs i also have same problem of creating water level
@@geodeltalabs THANKS
How did you create water level? Didn't learn that in school?!?
how did you create plain in arcScene, please explain that, thanks .
Please, how was the water level created ?
Thanks a lot guys
A very useful vide I like it, I have not understood about water level shapefile, how to make it
Great Video!!! Really helpful. Thank you!!!
Hello sir. Whenever I use my ArcSence to project the DEM to produce a 3D, it disappears. What would be the problem
very great. thanks
I really like you video!! great Job. However, I feel you skipped a lot o f the steps making video comprehension somehow difficult.
How did he made that water livel line.?
Can you please tell me that .
How can we export the intersection between DEM and water surface plane in SHP so we can have the surface water extent for specific water level?
How to visualise saltwater and groundwater interface using arcmap and arcscene
Which groundwater model are you using to generate this?
How to get river bed elevation along the length
I have some question though. How did you make your water level plane with inherent elevation values? Thanks
You can create a polygon, and assign an elevation (water level) value in the attributes table. After that, use the polygon to raster tool to convert the polygon into a raster, while making sure to select the specified value as it's field for the conversion process. This will create a constant value raster equal to the specified elevation value. You can then import that in to ArcScene
How to create water level ?
hi sir, your videos are awesome for learning , kindly tell me how to create water level and also how to create TIN model for arc scene
In ArcMap, you can create a polygon covering the area of the water surface. After assigning a numerical value which represents the water surface elevation, you can covert the polygon into a raster (and make sure to assign the value field the the column you created to specify the WL). After that you can bring that raster into ArcScene.
@@geodeltalabs pls make a video for it sir !!
Thx
No problem
Is there a way to make a surface that isn't flat? For example a water surface that would change elevation with the slope of the river?
An idea is to first create a set of lines with corresponding elevations, and then trying to create a surface using those lines. Then you can bring in the output raster to ArcScene
@@geodeltalabs Hi, could you please explain how would you do this? Thank You
Good video. Thanks. but How to make river section?
Using ArcScene
how can data are formed?
how I can get river level shp. ? it is the same as the water surface which extracts by using an index?
You can create it manually as a with a specified uniform value, and that value can be the water level
@@geodeltalabs thank you a lot, but i have another question :-; that , how I know water level ? where can I get it ? by data situ or what ? ;__;
i have a problem bro , how did you make that 3D view in Arcsene , you can tell me step tho in the comment section.

How to make the water level
You can create a polygon and specify the water level as a new field in the attributes table. The convert the polygon into a raster.
@@geodeltalabs thank you
Hi! Can you explain please how you create the water level shp file?
hi, create a raster with a constant value, and make that constant value equal to the water level you need. after that import that raster into ArcScene, and you will be able to visualise it as shown in the tutorial
@@geodeltalabs Thanks for your answer and please allow me to twist it a little more. Is it possible to create the base level rather a polygon with a constant water level, a raster with multiple Z-values? If yes, could you explain how, please? -Huge thanks!
Topo to Raster :) found it :) Thanks anyway!
how did you make a water plain here?? please ca you explain the process?
You can create a raster with a uniform value. First create a polygon (a rectangle preferably). In the attributes table, specify a single elevation value. This elevation value is the water level. Then convert the polygon into a raster, based on your previously specified single value. Once the raster is created, import it into ArcScene.
You could just create a constant raster via "Create Constant Raster" tool, and specify the value.
Volume
Thanks,
Thanks for watching. Cheers!
سلام مصطفى ممكن سؤال
could you please do a tutorial on calculate the volume of a raster using python?
This is actually in interesting idea. Will try to see if we can work something out
What's the unit of the Volume?
