How to Calculate the Square of a Matrix
THE SQUARE OF A MATRIX
The square of a matrix involves multiplying the matrix by itself.
Steps to Compute the Square of a Matrix:
1. Ensure A is a square matrix (i.e., it has the same number of rows and columns).
2. Perform matrix multiplication A*A by following the rules of matrix multiplication.
But if the matrix is not a square matrix, then squaring the matrix is not defined because matrix multiplication requires the number of columns in the first matrix to equal the number of rows in the second matrix.
However, there are Alternative Operations for Non-Square Matrices.
If you need to perform operations on non-square matrices, consider:
1. Matrix products with its transpose:
• ATA: Results in ...

Los Angeles Wildfire: How to Analyze Burn Severity using NBR in ArcGIS Pro
Просмотров 19112 часов назад
NORMALIZED BURN RATIO (NBR) The Normalized Burn Ratio (NBR) is a remote sensing index used to measure vegetation and detect burn severity in wildfire-affected areas. It utilizes the reflectance properties of vegetation and burned areas in the near-infrared (NIR) and shortwave infrared (SWIR) bands of satellite imagery. Normalized Burn Ratio (NBR) is used to identify burned areas and provide a m...

How to Calculate Latitude and Departure using Calculator | Latitude and Departure in Surveying
Просмотров 18421 день назад
In surveying, departure and latitude are components used to determine the horizontal displacement of a point relative to a reference line (usually in a traverse or coordinate system). They are derived from a distance and bearing of a line. Latitude: The latitude of a line refers to the projection of the line on the north-south (Y-axis). • It is calculated as: Latitude = Distance × cos (Bearing)...

How to Create Buffers from a DEM using ArcGIS
Просмотров 7628 дней назад
Creating buffers for a DEM involves identifying zones or regions at specific elevation ranges (or intervals) from a reference point, surface, or level. These buffers can represent areas of influence, flood zones, elevation bands, or other criteria, depending on the use case. Steps to Create Buffers for a DEM in ArcGIS Pro 1. Determine the Buffer Ranges Before starting, decide on the elevation r...
How to Calculate Height Above Flood Level using QGIS
Просмотров 184Месяц назад
Height Above Flood Level (HAFL) is a calculation used to determine how much higher a specific area is compared to a defined flood level. This is particularly important for flood risk mapping, hazard assessment, and emergency planning. Why Calculate HAFL? 1. Flood Risk Assessment: Identify areas safe from flooding by determining how much higher they are than the flood level. Prioritize evacu...

why my qgis dont have projection in raster part? only have Raster Calculator, Align Raster and Georeferencer
im using QGIS 3.14.16 version. Can anyone tell me how?
dont worry about the lesser likes and responce you made my hours of effort success thanks man form INDIA its abhi
You're welcome, Abhi. We're glad we could help! 😁
This was extremely helpful. Thank you so much!!!!
You're welcome. 😁

How can i export the rasterize data?
Its look like not good lines
Thank you so much for this!
You're highly welcome.
This is THE BEST, most easily understood, comprehensive and fast instructional video I have seen yet on this topic, you should make videos about how to do everything, thank you.
Wow! We'd keep giving the best. Have fun learning!
Loved that
We're glad you liked it. Keep watching our videos!
Why use execel to solve the matrix😢😢....will i use excell during exam period
Hello, Daniel. You won't use Excel in the exams. Check through the channel, we have solved some matrix problems manually. What you see in these kinds of videos is like the application of your understanding of the manual processes.
Please, stop teaching.
Oh! But why?
Good video sir Very very knowledgeable
We're glad you like it.
Good day and well done how about reference spot height to an exiting height of a structure
Hello. I think that's an application of what we have here. It depends on the engineer and surveyor to decide on how to achieve that.
Do it step by step. Don't scare with lots of calculations
Step by step and lots of calculations are synonymous; if you see the latter, know we are doing the former to achieve it. So, just be patient and learn. I wish you happy learning and understanding.
You just go straight to main thing More winning
Yes, thanks for watching.
Please am confuse on getting the af answer because mine is given me 21734275.45

Alright, we'd continue. Keep learning!
How can i get shape file of Diva gis
It's in the video!
Thanks
You're welcome, Bright.
Works like a charm. Thank you. 💪 👍
You're welcome.
I just tried this out, it worked perfectly well, but I wouldn't get other points around the drawing correct expect for only the first point I did link my drawing to
It has to! Please move the whole entity at one using the first point as the reference. The idea is to locate spatially the entity as a whole from where it was using the first point as reference. Since the extent didn't change, I'm not sure you'd encounter any challenges.
my left ear liked the video!
Really?
How come you still use AutoCAD 2007 in 2023 😭
I really don't know!

What version of qgis are you using in this video, please?
We used QGIS 3.34.9.

Please boss do a video on how to plot a record copy of a plan. Thank you
Interesting tutorial ❤
Thank you so much, I spent most of last night looking at videos and trying to figure this out and now I have my full answer. I had used GPS Visualizer but did not know I could get UTM coordinates from it as well. Cheers.
You're welcome. We're glad we could help. Keep watching!
@SurveyingSolution Will do. Cheers👍🏽
Please, Guide me, I followed the steps for the reprojection but the DEM is misaligning from the right location on the map
Hello, Saleh. Please confirm the projected CRS.
you need to drink some water before starting qgis
Thank you.
Thank you. I'm proud of you. Keep the great work on.
You're welcome, sir. Thank you for checking in.
There is some issue in coor lisp. That's the osnap mode will automatically turn off the nearest selection. So its create the problem like always ON the nearest selection.
That was very good. Thank you!
You're welcome.
Very Helpful🎉
Keep it up my brother. I love what you do sir👷
very helpful 😀
It's good you like it.
Great Tutorial..🎉

Thanks Sir for this lecture, its been very helpful to me.
You're welcome.
Is it actually 3D though? It seems 2D here still, and whenever I follow these steps I get it still in 2D. My dem has a depression in it and this does not show
Hello, Rock. If you're modelling a relatively flat terrain, you might not actually see much exaggeration. And if yours have depression or valley, and you didn't see it, please redo and pay attention to the details. We hope this helps!
@@SurveyingSolution ah yes mine is relatively flat terrain so I get it now. Thanks so much!!
You're welcome.
