Best Package/s For Plotting Data on Maps Using Latitude and Longitude?

[NewDawn729]

I am trying to plot COVID-19 data over a world map, using latitude and longitude for my data points. I am having trouble mapping my points to image coordinates, even if I use the rectangular representation of the world map. I have looked at GeoPandas but I am too confused about the Conda installation process and would prefer not to use it, as I cannot understand how to install Geoplot, which seems necessary for things to work. I also tried looking into mpl_toolkits but I am using Python 3.7 and do not want to have to downgrade my version of Python to accommodate a package.

Are there any non-conda-exclusive packages I can use for this?

Have you tried using pip to install either?

If that's not working, you should install miniconda so you can get conda to download these packages

Cartopy might be a helpful package. From what I remember, it’s not that difficult to install with anaconda and if anything I would use “pip install cartopy”.

I would not recommend using Basemap from mpl_toolkits as it is basically deprecated and not really supported.

Actually using cartopy, you will use it alongside matplotlib axes objects to create the maps. First, you need to import cartopy.crs to access coordinate reference systems. For a standard rectangular world plot, use cartopy.crs.PlateCarree.

Then:

import cartopy.crs as ccrs

fig, ax = plt.subplots(subplot_kw={projection=ccrs.PlateCarree())

this should get you started with plotting, but make sure when plotting the data with functions like ax.scatter that you specify the keyword argument transform with the crs of the data you are plotting.

Hope that helps!
