How to do interpolation with extra variable by using kriging
@GeoRGBCommunity
@GeoRGBCommunity 4 күн бұрын
The interpolation with an additional variable could refer to other variants of kriging, such as cokriging or kriging with external drift. Cokriging allows you to use one or more auxiliary variables correlated with the primary variable to improve estimation accuracy. On the other hand, kriging with external drift uses an external variable as a trend to guide the interpolation. For more specialized courses, please visit our website at giscourse.online/.

Hello! I am watching this course with the intent to "redo" these concepts in Python with packages such as Geopandas, Seaborn, Geostat and PyKrige, do you think Python is the way to go moving forward? I have not been having any trouble following along step by step with just python!

Hello! That sounds like a great exercise to learn both Python and QGIS at the same time. Python is definitely a promising tool for the future of GIS, and your approach of redoing these concepts with packages like Geopandas, Seaborn, Geostat, and PyKrige is a smart move. Keep it up-you're on the right track!

Hello Marcel, I want to thank you for your valuable time you spent for making these extremely useful videos on a complex topic like kriging. It helped me a lot to remove my weaknesses. 🎉 In video #8 (time: 17:55), you said that krige.cv estimates the value at the centre of the pixel and compares with the observed value within that pixel. I think by default, krige.cv uses leave-one-out cross validation approach. Please see the Details section of page 31 of gstat package documentation. I want to cite your videos in my paper, but I don't know how 😢.

Hi! If you've followed the tutorial step by step and still encounter the error "AssertionError: ERROR: Sentinel-2 image missing," I'm not sure what might be causing it. It could be a temporary issue, so you might want to try again later. Another possibility is that something has changed in Google Colab that is affecting the process. In the meantime, you could also check for any updates or additional instructions related to the tutorial.

Wonderful video, I love how you explain the black box in detail so that people can understand the math behind it. At 21:19. I think the residual means the difference between the regression value and measured value at each location on the X-axis, so a proper way to present the residual is a line from the point down to the regression line, not perpendicular to the line, am I right?

I also have another question, since Kriging can only work for interpolating stationary datasets, we use the residual values and their fitted semi-variogram model to perform Kriging, and then back-calculate the GW elevation and label them as predicted values, am I right?

If you're looking to watch the video with subtitles in a different language, here’s a quick guide: On the KZbin video player, you’ll find several icons on the bottom right corner. Next to the subtitles icon, there’s a gear icon for settings. Click on it, then select 'Subtitles' followed by 'Auto-translate'. From there, you can choose the language you prefer for the subtitles. That’s all there is to it! Best regards.

dear professor ,all of your videos are great and really useful .I want to follow the tutorials and implement them for my data that are in a mountain area in europe, I want to interpolate temperature by using universal kriging and considering elevation as one of the variables , in your opinion this method will work ?
@GeoRGBCommunity
@GeoRGBCommunity Жыл бұрын
I'm glad to hear you've found our videos useful! Regarding your specific inquiry about universal kriging for temperature interpolation in alpine regions: If your data exhibits a spatial trend, say, in a specific direction like northwards, universal kriging might be suitable. However, if you're keen on integrating elevation as a co-variable with temperature, kriging with external drift would be a more fitting approach. Warm regards
