Plotting¶
Every region has a plotting function, that draws the outline of all (or selected) regions on a cartopy map. We use the predefined SREX regions as example.
Import regionmask and check the version:
import regionmask
regionmask.__version__
'0.6.2'
Plot all regions¶
Do the default plot.
regionmask.defined_regions.srex.plot();
<cartopy.mpl.geoaxes.GeoAxesSubplot at 0x7fc37f81ce90>
Plot only a Subset of Regions¶
# load cartopy
import cartopy.crs as ccrs
# regions can be selected by number, abbreviation or long name
regions = [11, "CEU", "S. Europe/Mediterranean"]
# choose a good projection for regional maps
proj = ccrs.LambertConformal(central_longitude=15)
# do the plot
ax = regionmask.defined_regions.srex.plot(
regions=regions, add_ocean=True, resolution="50m", proj=proj, label="abbrev"
)
# fine tune the extent
ax.set_extent([-15, 45, 28, 76], crs=ccrs.PlateCarree())
Plotting the region outlines only (no map)¶
regionmask.defined_regions.srex.plot_regions();
<matplotlib.axes._subplots.AxesSubplot at 0x7fc370d3ff50>
Note
This does not create a cartopy axes.
To achieve this, you need to explicitely create the axes:
import matplotlib.pyplot as plt
f, ax = plt.subplots(subplot_kw=dict(projection=ccrs.PlateCarree()))
regionmask.defined_regions.srex.plot_regions(ax=ax, line_kws=dict(lw=1));
