- in this tutorial you can see how can you
1. Create a RASTER elevation model
2. Elevation Model with Fault line & without fault line
3. Raster Model Unit Conversion
4. Image Analysis
5. 3D DEM
For the data used in this video please follow this link,

very helpful tutorial, sir do you have a tutorial on how to prepare a probable area of landslide and also on how to calculate river water level increase using rainfall data
Thank you Mr. Nazamul Peyal it was very interesting
Glad to help mam. Please let me know if you require tutorial on some other topic. Thank you.
Hi there. Very interesting video. A question here: what is exactly the "z" data in the spreadsheet at the beginning? Is it elevation of water during a flooding event, measured either on the field or through remote sensing?
Can i make flood model and forecasting of flood using arc gis? . . Please guide me sir
Sir,
Please clarify doubts from the result obtained.
1. As per the tutorial you provided we acquired flood level map with (-189) to (90). So actually the minus(-84) value stands for what ?
2. While I processed the classified flood level ,As per the tutorial the highest value 91is given to flood level five, but the classified flood level five zone is falling on the present reverine & esturine system. As per the present flood inundated scenario most of the flood free zone are affected. Inundation .How can we relate results ?
3. Mostly flood affected area is falling on the free zone.Then how can we compare then result?
Hi Jibin,
You can use "SetNull(Float("idw_cmp"-"dem_bgdv1_m")
hey there ... how could i get the exel information ?
please helpe i have collage project and i want to use your vidio as a resourse
I don't understand a sense of the XYZ data file. The Z value is in meters, but what it is. Value variability c.a. 3-20[m]. It is deep of the flood?
the datasets of X,Y & Z are defining the location and the flood Water height occured in the area. This data is from past years' analysis. I have forgot to mention this in the video.
Dear Sir,
Your given google drive link does't work. Can You please update that??? Thank You
Can u upload this excel file and shape for practice purpose
nice.. very useful!!
Subscribe for more videos. Next lesson will start very soon
i am new on this, how can we create faultline shapefile or from where can we download this? Secondly if you know the process of flood prediction area kindly guide me on this if it is possible for you.
Thanks your great job.
Is it possible to export 3D map from ArcGIS such as ArcScene?
If it is possible please inform or if it is not possible, how can I export a 3D visualized map in pdf.
ArcMap is not a very suitable platform for 3D visualizations but you can still do it.
hello sir, i don't have excel data. is it possible by the DEM data
How to create raster elevation model without the fault line? What is the use of the fault line in flood level calculation?
Just don't add the fault line where it was added.
Fault line is like when there are some sort of barrier which disrupt the continuous model. Like if there is a dam, then then model won't be similar without a dam. So we add a fault line there.
how did you get the flood level calculation chart as 0-0.3 flood free area,0.3-0.9 flood level 1,etc?
This data is my country [Bangladesh] standard obtained from Institute of Water Modeling & Flood Management. Which I guess will vary for different locations
ok thank u
are all the values in the layers as for example in Dem, flood lvl, etc in meters so that you can reclassify each of them in meters as per requirements
Yes they are in meters
Wonderful video
Glad that you liked it.
Thanks
Hi,
I have doubts regarding interpolating flood levels using IDW. Can we rely on the interpolated values?
Interpolation is a mathematical formula where intermediate values are unknown. If all kind of interpolation is applicable to all places, that would be a really good question. And about flood level modeling IDW is definitely a well-practiced and an accepted method.
@@NazmulPeyal okay. Could you please share some literatures which follows similar procedure..
where to get that excel file please help me
The best since thatis for the sake of people peace
hi , can you please share the link of data
could you plz tell me how i will get X,Y &Z value for a specific area
Government Department Associated with Flood Management. In my case, Institute of Water Modeling, Bangladesh.
file : fault.shp lấy ở đâu được
my idw doesn't work if i give environment condition like you.
What happens there?
Nazmul Peyal It shows IDW failed
Error Code 99999
@@jeetsharma7583 Error code 99999 is the error which is undetected. Try re installing everything if the problem persists.
Nazmul Peyal okay
what is the fault line?
Some obstacles which will prevent the water flow, River dam for example
@@NazmulPeyal if there is no obstacles, can i skip the fault line process?
plz sir provide me an excell data
