‘Kite’ is an excellent tool that can help you boost your productivity when it comes to programming with its free Artificial Intelligence (AI) powered coding assistant. Kite is a plugin which provides smart completions and documentation as you’re typing-in your code, and its compatible with most of the well-known IDEs such as PyCharm, Spyder and VS Code. I absolutely love it, and recommend you guys to try it out as well.

Thank you so much! It's very helpful. I'm using Geopandas in our research group for understanding the disease distribution in different location.

[@user-bk5ep5wy8r]

Great video. Thank you so much.

[@potpie2004]

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.

[@augustarcher6407]

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

[@bakercain265]

@August Archer Yea, have been watching on Flixzone} for since december myself =)

[@iraesteban8998]

@August Archer yea, I have been using Flixzone} for since november myself =)

Hi can you also make a video on machine learning with netCDF files? Thank you very much. Love your way of tutorials.

[@evertoncastro5647]

Muito obrigado!!!

[@wasifeelahi1341]

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?

[@geodeltalabs]

Thanks for the suggestion. We will try incorporate your idea for our future tutorial videos

[@DileepGuptagoodman]

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

[@GIS-Engineer]

How can landuse classify the satellite image

[@Anurag-sq4yc]

Sir can you make tutorials on Pytorch for geospatial data

[@marcoherbas81]

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?

[@mucahitugurlu7324]

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.

[@razzlejazzles]

# 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))

[@harithameka8328]

can you please make a video plotting streamlines please thank you uploading video on using geopandas

[@princee9385]

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

[@razzlejazzles]

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.

[@arnavaghatak1125]

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

[@Agronomistapolo]

When I try to calculate the area of USA (Multipolygon) I obtained an wronong area. I changed the src.

[@geodeltalabs]

Yes, you better use a projected CRS for geometrical computations like distances and areas.

[@akolamkar333]

Hi. can you tell me how to generate vector tiles with the help of shape files in python.

[@razzlejazzles]

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)

[@ayeshareezwana8542]

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]

Hi, yes absolutely. You may check this video, it shows how that can be done kzbin.info/www/bejne/l6GooI2Lp5yWZ7c

[@ayeshareezwana8542]

@@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?

[@geodeltalabs]

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?

[@ayeshareezwana8542]

@@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 :-)

[@crtnnn]

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?

[@geodeltalabs]

Are you working with an abnormally large dataset?

[@travelissimple7015]

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

[@razzlejazzles]

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.

[@iceiceisaac]

world_data = world_data.to_crs(epsg=3857) is not the format

Hi Axel, the link has been updated. Thanks for notifying :)

I can not install "Geopandas". please help me

[@geodeltalabs]

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 :)

[@razzlejazzles]

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

please work in a white theme, and please zoom.
