My shapefile is from a much bigger place than my data, and I want to zoom in. In Python, choropleth maps can be created using various libraries, such as matplotlib, plotly, geopandas. Rasterio is a package for reading and writing But I would like to plot the map of only one continent, for example "South America" by using geopandas library. Both layers must be in the same Coordinate Reference System (CRS). Formatting it and editing the colormap legends. GeoDataFrame returns a Matplotlib Axes object. GeoPandas provides a high-level interface to the matplotlib library for making maps. The gdf will be clipped to the full extent of the clip In this episode, we will introduce how to crop raster data into the desired area. Choropleth maps are a powerful tool to display data over a geographical region. To plot the active geometry, call GeoDataFrame. The other is a polygon(s) shape file. I am using 'naturalearth_lowres' default map of The usual. That is an efficient way how to do so, especially with GeoPandas 0. x Anaconda distribution, git and bash to set things up.
