Spatial Interpolation (IDW) using QGIS

In this video spatial interpolation (Inverse Distance Weighted) is performed using QGIS to predict unknown values from known.

Thanks so much! my professor made a video explaining to set the pixel size in the interpolation to .0001 and i got a big black box and then i could not cut it and this was so helpful! finally

Very informative professional video without unnecessary words, all is relevant and to point. Thank you

What do the numbers in the scale themselves (those you can see next to the colour when he's choosing the colour ramp) represent ? Is it just where the rainfall was the most dense in the area ? Or is it something else as well ? This video was very helpful either way !

Hey sir! Great vid. I happen to have a single raster file and I would like to interpolate it. (plus the polygon of interest with no attributes). You happen to have a vid on that?

[marinalola]

thank you, this helped a lot btw which version of QGIS did you use in this video ?

[sphelelelubanyana]

Thank u...i wanted to create heightmap from a gpx file...🎉

Good video How we can make interpolation with rain fall interval (eg 500 - 750, 750 -1000, 1000- 1250)

How can i interpolate with two or more attribute fields (for instance like wind and rainfall in this vedio).
What if i have to Interpolate considering both the values.

[amolrupakheti]

Thank you for the video. How can I extract the values at the set of points that I want?

[anujas]

Sir, i create boundary map like you and run interpolation. But the boundery map is behind the raster image what was the reason?

Hello! How can I use this technique for a time series data? Thank you

[haruhitkunwar]

Great videos and really helpful. Is it possible to connect you on some social media? That would be really appreciated.

[akidifiona]

this is a very beautiful video. so i have tried out the same but the minimum and maximum values displayed doesn't capture all my data. how do we make sure that all data are being captured?

[BiggBoss-nb]

Sir, I wanna know about the minimum number of sample stations in IDW method?

[jaiingle]

can you tell the usefulness of this technique?

[ashwinib]

how to get value of rainfall for particular pixel or lat long

[crispusallen]

Hi, how do we make gridded maps of maybe 50, 100 or 200m resolution. Then, are we able to interpolate the daily precipitation data by IDW?

[unknownotaku]

I need help sir. After choosing my vector layer for the IDW Interpolation, no "Interpolation Attributes" showed up. :((

[mahansirirhandzu]

tried this but on interpolation parameters my parameters aren't coming, only latitude and longitude

[vincentcheng]

The IDW does not show up after I click run, why?
