For those updating from an older version of cartopy, the what’s new page outlines ...Description. There seem two existing approaches to implement curvilinear projections using matplotlib, projection and axisartist.The current implementation of cartopy follows the projection approach, which shows a nice consistency with the general matplotlib workflows. However, handling ticks, ticklabels, gridlines with flexibility seem still a challenge.Plotting in “geographic projection” (WGS84) #. Here, we plot countries as patches on a lat/lon (WGS84) map (data from Natural Earth Data again). We again extract the features using - the OGR.Layer SpatialFilter and - wradlib.georef.get_vector_coordinates. Then the patches are added one by one via wradlib.vis.add_patches.For example, one may define a patch of a circle which represents a radius of 5 by providing coordinates for a unit circle, and a transform which scales the coordinates (the patch coordinate) by 5. Return the path of the ellipse. Return the vertices coordinates of the ellipse. New in version 3.8.import cartopy.crs as ccrs import numpy as np def scale_bar (ax, length=None, location= (0.5, 0.05), linewidth=3): """ ax is the axes to draw the scalebar on. length is the length of the scalebar in km. location is center of the scalebar in axis coordinates.

To plot this data with CartoPy, we’ll first need to project it into a new CRS. We’ll use a CRS defined within CartoPy and use the GeoPandas to_crs method to make the transformation. Now that our data is in a CRS based off of CartoPy, we can easily plot it.Prices vary for Cabbage Patch Kids dolls depending on the type of doll and year that it was made.
