[@potpie2004]

Hi, just wanted to let you know that I enjoyed this tutorial. I'm completely new to python and programming and was able to follow along in the 2-part series.

Great job, please continue

[@farahnusrat5639]

Hi. Can you please make a tutorial for doing kriging using python/R and how to select the variables best for getting the lowest RMS value? It will be really helpful. Great works. Keep it up

[@geodeltalabs]

Thanks for the suggestion. We will include this into our upcoming tutorial sessions. Stay tuned 😉

[@amirrezasalehi3566]

Thanks for great videos

[@tubuobaggio]

I definitely enjoyed the tutorials, i had to work from Jupiter instead because of the reprojecting problem will occurred when i was trying to project the data, This was because of the " pyproj" file of which i don't know how to trouble shoot. if you could help with solving the problem i will be more than happy

hi. great tutorial. I have a question. What if I plot a points shapefile over your polygon shapefile, then make a buffer of 500 meters on one of the point. And after the buffer, clip the points inside that buffer zone? Is it possible? I have done till the buffer part, but I cannot clip the points inside the buffer. Thanks

[@geodeltalabs]

Hi, have you tried replacing the existing 'geometry' column (point) with the new 'geometry' column (polygon) ?

How to add the names of each district?

[@deepikarao2593]

Hi, map_districts.plot() gives output Out[56]: but the map is not seen

[@geodeltalabs]

Which version of Spyder are you using? If you are using the latest version of Spyder IDE, the plots will be shown by default under the special 'plots' tab (next to the variables explorer).

[@geodeltalabs]

In case if this does not work for you, I suggest you to try and update matplotlib to the latest version, which is matplotlib 3.2.1. You can do this by following the following steps: 1. Right click on 'Anaconda Prompt' and open it as administrator 2. type the following: pip install matplotlib==3.2.1 --user 3. Close and restart Spyder and try to run your script

[@deepikarao2593]

@@geodeltalabs This got it running. Thank you

[@yinkai1718]

Hi, may you release the python script of this tutorial. Maybe we can learn better with this tutorial

[@geodeltalabs]

Hi, the link to download the script is added in the description

[@nept4ne]

Hi GeoDelta Labs, could you help me please?. In the console when I type nep_districts.plot it does not appear the map. It shows this message:

[@geodeltalabs]

Hi Harry, did you add the brackets at the end? nep_districts.plot()

[@nept4ne]

@@geodeltalabsThanks for your time, first I did not type (), then I did and show this "the descartes package es required for plotting polygons in geopandas". How can install descartes in anaconda prompt? "conda install descartes" or "pip install descartes", I use windows.

[@geodeltalabs]

@@nept4ne you can open anaconda prompt as administrator, type pip install descartes That should be sufficient :)

[@nept4ne]

@@geodeltalabs It worked fine but when I compiled from the reprojecting part, it showed this "RuntimeError: b' no arguments in initialization list". why is so hard but I learning.

[@geodeltalabs]

@@nept4ne This is a common problem related to the pyproj package installation. You can do the following to fix that. 1. Go to the location which you have installed Anaconda3 2. Inside Anaconda3 folder, go to Lib-> site-packages -> pyproj 3. Inside the 'pyproj' folder, you will find a file called 'datadir.py' 4. Open the 'datadir.py' using Notepad 5. Edit the end of the file path to be: ...Anaconda3/Library/share (you may have to change the '/' to '\' when specifying the path) 6. Save the notepad file. exit. Restart Spyder 7. Try reprojecting again
