stock_img doesn't work with Orthographic projection

[rabernat]

Description

Calling .stock_img() with Orthographic projection does not show anything.

ax = plt.axes(projection=ccrs.Orthographic())
ax.stock_img()

Shows this

This occurs with Cartopy 0.16.0 and matplotlib 3.0.1 (latest releases of each).

Instead, if I use Cartopy 0.15.1 and matplotlib 2.1.0 (from an older setup), I see this:

cartopy 0.15.1 py36_5 conda-forge
proj4 4.9.3 4 conda-forge

But what version of Proj were you using with Cartopy 0.16.0?

[dopplershift]

I can't reproduce on Python 3.7 with Cartopy 0.16 and Proj 4.9.3.

[rabernat]

$ conda list proj
# packages in environment at /opt/conda:
#
# Name                    Version                   Build  Channel

pyproj                    1.9.5.1          py36h508ed2a_6    conda-forge

[rabernat]

Update: I realized that I mistakenly copied the conda / pip envs from the working environment (0.15.1) rather than the non-working one (0.16). I have updated my original post with the correct environment listing.

Looks like this could be a proj4 version issue?

[QuLogic]

Are you absolutely certain those versions don't work with Cartopy 0.16.0?

[dopplershift]

I take it back, I'm running pro 4.9.3. I've corrected above.

[BartSchipperijn]

I have a similar problem. When I plot a collection of filled polygons (as a PolyCollection) + the stock image on a map with PlateCarree projection, the polygons and the stock image are perfectly visible. When I plot the same PolyCollection + stock image on a map with the Orthographic projection, the polygons and the stock image are not visible. However, the coastlines, borders etc. are perfectly visible on both projections.

I am running Cartopy 0.17, Matplotlib 2.2.3 and Proj4 4.9.3.

[QuLogic]

Difficult to say with that little information.

[rabernat]

Are you absolutely certain those versions don't work with Cartopy 0.16.0?

I have no way to explain it, but the problem has gone away. I can't replicate any longer.

[QuLogic]

I'm fairly certain this was a bug in Proj 5.0.x that you may have not noticed get downgraded at some point. Current Cartopy raises a warning about it.

[BartSchipperijn]

The problem disappeared in my environment when I added "transform=ccrs.PlateCarree()" to the PolyCollection parameters.

[QuLogic]

Please see the understanding transforms section of the documentation.
