thank you for this tutorial - I used this in conjunction with your 2 part series with nepal as the example. Once again was helpful. I'd recommend linking to your 2 part series in the description as I believe that was a better baseline for a beginner if they are struggling with t his exercise.
Thank you for the great video! I have one question, how can I do to plot some specific countries, instead of removing Antarctica let's say I would like to show in color countries like US, France and Australia and the rest uncolored?
you could try something like this.. russia =world_data[world_data.NAME.str.contains('Russia')] ax = world_data.plot(figsize =(12,12),color ='darkgreen',edgecolor='black') russia.plot(color = 'blue', ax=ax) *Let's say that you'd like to highlight russia in the world map with a different color. All you need to do is ,first get the russia's data and plot it with the world map. Just try the code that I've written and you'll understand what I meant sir. You could also do this with different countries too with the same way.
# Create a new column for the desired countries world_data["color"] = 0 world_data.loc[world_data["NAME"].isin(["United States", "France", "Australia"]), "color"] = 1 # Plot the desired countries in a different color world_data.plot(column='color', cmap="Set1", legend=False, figsize=(7,7))
Thanks again... your videos are helping me a lot in my Ph.D. project. Could you please make a video on the quiver plot from the NetCDF file that contains u, v and time data?
i am not able to get the map and other data on console it is only visible on plots. if i want to see the columns the following error is shown please help me shape_file.columns() Traceback (most recent call last): File "", line 1, in shape_file.columns() please help me
When I open the attribute table (geodataframe) and scroll over to geometry, my spyder starts to lag extremely (works extremely slow). what might be the issue?
ArcGIS shapefile files are composed of mandatory files (SHP, SHX and DBF) and optional files (PRJ, XML, SBN and SBX). You want to just select the shp file for this tutorial when coding.
import subprocess # Set the path to the input shapefile input_shapefile = "path/to/input.shp" # Set the path to the output directory for the vector tiles output_directory = "path/to/output/directory" # Set the zoom levels to generate tiles for zoom_levels = "0-12" # Set the name of the layer to use in the vector tiles layer_name = "my_layer" # Call the tippecanoe command to generate the vector tiles tippecanoe_command = f"tippecanoe -o {output_directory}/{layer_name}.mbtiles -z {zoom_levels} -l {layer_name} {input_shapefile}" subprocess.call(tippecanoe_command, shell=True)
Hi. Thank you. I have a question. Is there any way I can extract the latitude and longitude from the geometry and add them as separate columns in the geopandas dataframe??
@@geodeltalabs Hello ,Thank you very much. My geometry data is in multipolygon and if I try to extract the long/lat following this, it shows me an error "MultiPolygon' object has no attribute y" . I am new to geopandas. Can you please give me an idea how to extract long/lat from the multipolygon?
Hi, it's expected if that's a polygon. I was under the impression that you were referring to point objects. A polygon is actually made up of many points (vertices), so I'm not sure what exactly you mean by extracting lat and lon of a polygon? Are you referring to maybe the centeroids' coordinates of each polygon?
@@geodeltalabsHi, I did a (.centroid) operation over the multipolygon which results in a point object and returns me for an example point(103.70469 ,1.34714). I think this is my lat and long. Correct me please if I am misleading myself. Thank you very much. I love your channel :-)
Hi, please refer to the 'Beginner's guide to geopandas tutorial" which I have done quite some time ago. in the first few minutes of the tutorial, you will learn how to install geopandas :)
Thank you for your tutorial. But when I use get area for each country, I get this erro. "C:\Users\user\Anaconda3\lib\site-packages\ipykernel_launcher.py:1: UserWarning: Geometry is in a geographic CRS. Results from 'area' are likely incorrect. Use 'GeoSeries.to_crs()' to re-project geometries to a projected CRS before this operation. """Entry point for launching an IPython kernel." Could you explain me why and how can I resolve this? Thank u a lot
It doesn't affect anything, it is just letting you know that since the area is calculated by degrees is wont be as accurate as it would be if it was calculated by sq km for example.
Thank you so much! It's very helpful. I'm using Geopandas in our research group for understanding the disease distribution in different location.

pro tip: you can watch movies at Flixzone. Been using it for watching a lot of movies these days.

Are you working with an abnormally large dataset?
You are awesome. But I want to know what exactly is to be considered before choosing your shp file since there are many on the zipfile. Thanks

Hello sir your video is very informative. Please tell us how plot the legend with color and country name to represent the each with different color
Muito obrigado!!!
Sir can you make tutorials on Pytorch for geospatial data
Great video. Thank you so much.
When I try to calculate the area of USA (Multipolygon) I obtained an wronong area. I changed the src.
Yes, you better use a projected CRS for geometrical computations like distances and areas.
Hi. can you tell me how to generate vector tiles with the help of shape files in python.
import subprocess
# Set the path to the input shapefile
input_shapefile = "path/to/input.shp"
# Set the path to the output directory for the vector tiles
output_directory = "path/to/output/directory"
# Set the zoom levels to generate tiles for
zoom_levels = "0-12"
# Set the name of the layer to use in the vector tiles
layer_name = "my_layer"
# Call the tippecanoe command to generate the vector tiles
tippecanoe_command = f"tippecanoe -o {output_directory}/{layer_name}.mbtiles -z {zoom_levels} -l {layer_name} {input_shapefile}"
subprocess.call(tippecanoe_command, shell=True)

thank you uploading video on using geopandas
Hi can you also make a video on machine learning with netCDF files? Thank you very much. Love your way of tutorials.
world_data = world_data.to_crs(epsg=3857) is not the format
I am unable to download the exercise file, its showing corrupted!!!
Hi Axel, the link has been updated. Thanks for notifying :)

This is giving me syntax error...can someone help

I had a lot of trouble downloading geopandas with anaconda. What ended up working for me was putting "pip install geopandas" in my anaconda prompt
