When plotting on a map chances are you will be dealing with shape files. We’ll need geopandas to read and write spatial data, manage data projections (i. The only requirement that cartopy has for plotting spatial (vector) data is that it’s loaded into a Shapely geometry class (e. The second part is writing a function that parses a rgb color code based on the field value to the trace function. We then plot the values as patches. We take products like Google Maps for granted, but they're an important convenience. read_file('multiline_example_filepath. Clearing up a Pandas misunderstanding. Bokeh plots can also consume XYZ tile services which use the Web Mercator projection. We first cover how to work with GeoPandas and then dive into plotting with Bokeh. Once the files are downloaded, we can use GeoPandas to read the GeoPackages: Note that the display() function is used to show the plot. HoloViews and GeoViews are pretty new, and I'm a big fan.
