Oceans wrongly displayed with TransverseMercator and central_longitude #1685
Description
Description
Oceans from Natural Earth do not display correctly with TransverseMercator setting cenral_longitude to other than 0.
The whole Earth appears covered in water, several times judging for the opacity.
Other projections seem to work fine, and other elements of PhysicalEarth work as well.
Code to reproduce
This code includes working and non working pieces. Select the first PROJECTION to see the bug.
import cartopy.feature as cfeature
from cartopy import crs as ccrs
import pylab as plt
PLATE_CARREE = ccrs.PlateCarree()
# This projection doesn't work:
PROJECTION = ccrs.TransverseMercator(central_longitude=15, scale_factor=0.9996, approx=False)
# These do
PROJECTION = PLATE_CARREE
PROJECTION = ccrs.AlbersEqualArea()
PROJECTION = ccrs.TransverseMercator(central_longitude=0, scale_factor=0.9996, approx=False)
PROJECTION = ccrs.Mercator(central_longitude=15)
lat = [59.234952, 59.561187, 60.0401]
lon = [17.851566000000002, 17.552861, 18.680685999999998]
fig, ax = plt.subplots(1, 1, subplot_kw={'projection': PROJECTION})
ax.scatter(lon, lat, transform=PLATE_CARREE)
lakes_10m = cfeature.NaturalEarthFeature('physical', 'lakes', '10m',
edgecolor='b', facecolor='b', alpha=0.1)
ocean_10m = cfeature.NaturalEarthFeature('physical', 'ocean', '10m',
edgecolor='b', facecolor='b', alpha=0.1)
ax.add_feature(lakes_10m) # This one works
ax.add_feature(ocean_10m) # This doesn't
plt.show()
