Some countries borders not showing up in map

[guidocioni]

I remember seeing this already a long time ago but I never managed to solve it.

I'm plotting a map using this

m = Basemap(projection='merc',
                llcrnrlat=extents[2],
                urcrnrlat=extents[3],
                llcrnrlon=extents[0],
                urcrnrlon=extents[1],
                lat_ts=20,
                resolution='h')

m.fillcontinents(color='lightgray', lake_color='#2081C3', zorder=1)
m.drawlsmask(land_color=(0, 0, 0, 0), ocean_color='#2081C3',
                 resolution='f', lakes=True, zorder=2, grid=1.25)

ax = plt.gca()

m.drawcountries(linewidth=0.8)
m.drawcoastlines()

m.readshapefile(f'{SHAPEFILES_DIR}/ITA_adm_shp/ITA_adm1',
                        'ITA_adm1', linewidth=0.8, color='black', zorder=5)

but some countries (like Switzerland) don't show up.

Weirdly enough when centering the projection over France Switzerland shows up

Hi @guidocioni! Which OS, Python version and basemap version are you using?

[guidocioni]

Hi @guidocioni! Which OS, Python version and basemap version are you using?

CentOs 7
python 3.10.6
basemap 1.3.6 py310he832c09_0 conda-forge
basemap-data 1.3.2 pyhd8ed1ab_1 conda-forge
basemap-data-hires 1.3.2 pyhd8ed1ab_1 conda-forge

[molinav]

Sorry to bother again, can you share the value of your extents list? Then I can try to reproduce the problem in my laptop.

No worries, and you're right I haven't attached them 😛

[6.0, 19.0, 36.0, 47.7]

[guidocioni]

Hello @molinav , do you have any update on this? Thanks

[molinav]

Hi @guidocioni! Sorry for being so late with this. For the moment, I can confirm you the bug using the following code snippet:

import sys
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.basemap import __version__ as basemap_version
from mpl_toolkits.basemap import Basemap

print("Python version: ", sys.version)
print("Basemap version:", basemap_version)

plt.clf()
ax = plt.gca()

extents = [6.0, 19.0, 36.0, 47.7]
bmap = Basemap(projection="merc",
               llcrnrlat=extents[2],
               urcrnrlat=extents[3],
               llcrnrlon=extents[0],
               urcrnrlon=extents[1],
               lat_ts=20,
               resolution="h")

bmap.drawcountries(linewidth=1, color="blue")
bmap.drawcoastlines(linewidth=1, color="red")

This returns the following in my console:

Python version:  3.11.2 (tags/v3.11.2:878ead1, Feb  7 2023, 16:38:35) [MSC v.1934 64 bit (AMD64)]
Basemap version: 1.3.8

And the following image is obtained, with Switzerland borders missing, as in your original message:

I would need to check the internals of Basemap.drawcountries, to see if the Switzerland borders are read correctly from the basemap_data_hires files (which I would expect), and at which point the borders are filtered out from plotting.

[guidocioni]

Yes from my previous experience there is some "sweet spot" while setting the projection extents that causes the Switzerland borders to be exlcuded.
However, I don't know enough about the basemap internals to understand where and how the filtering is done.

[molinav]

I have found the code block that is causing the issue:

basemap/packages/basemap/src/mpl_toolkits/basemap/__init__.py

Lines 1371 to 1373 in c20c146

	if poly.intersects(boundarypolyll):
	if name != 'gshhs' or as_polygons:
	geoms = poly.intersection(boundarypolyll)

When the Switzerland border is picked in your example, poly.intersects(boundarypolyll) checks if the polygon and the boundary box are not disjoint (this is calling GEOSIntersects internally), and it is returning True. This means that this if-block identifies successfully that the Switzerland polygon needs to be added.

In the next lines, geoms = poly.intersection(boundarypolyll) is computing the concrete part of the Switzerland polygon within the boundary box (because basemap does not want to draw anything outside the boundary box), and surprisingly it is returning an empty list.

So there is clearly a bug here to be inspected more, because it cannot be that we identify the polygon and the boundary box as not disjoint, but when asking for the concrete polygon coordinates inside the boundary box we get none.

I am still not sure where the bug comes from, but it is either GEOS itself (I would be surprised) or the Cython interface to GEOS. I will try to test this with a newer GEOS (since the basemap wheels bundle an old GEOS, version 3.5.1 for basemap 1.3.x) to confirm that the Cython interface needs a look.

[molinav]

Bingo, the issue is in the Cython interface:

basemap/packages/basemap/src/_geoslib.pyx

Lines 275 to 316 in c20c146

	def intersection(self, BaseGeometry geom):
	cdef GEOSGeom *g1
	cdef GEOSGeom *g2
	cdef GEOSGeom *g3
	cdef GEOSGeom *gout
	cdef char answer
	cdef int numgeoms, i, typeid
	g1 = self._geom
	g2 = geom._geom
	g3 = GEOSIntersection(g1, g2)
	typeid = GEOSGeomTypeId(g3)
	if typeid == GEOS_POLYGON:
	b = _get_coords(g3)
	p = Polygon(b)
	pout = [p]
	elif typeid == GEOS_LINESTRING:
	b = _get_coords(g3)
	p = LineString(b)
	pout = [p]
	elif typeid == GEOS_MULTIPOLYGON:
	numgeoms = GEOSGetNumGeometries(g3)
	pout = []
	for i from 0 <= i < numgeoms:
	gout = GEOSGetGeometryN(g3, i)
	b = _get_coords(gout)
	p = Polygon(b)
	pout.append(p)
	elif typeid == GEOS_MULTILINESTRING:
	numgeoms = GEOSGetNumGeometries(g3)
	pout = []
	for i from 0 <= i < numgeoms:
	gout = GEOSGetGeometryN(g3, i)
	b = _get_coords(gout)
	p = LineString(b)
	pout.append(p)
	else:
	#type = PyBytes_FromString(GEOSGeomType(g3))
	#raise NotImplementedError("intersections of type '%s' not yet implemented" % (type))
	GEOSGeom_destroy(g3)
	return []
	GEOSGeom_destroy(g3)
	return pout

After the call to GEOSIntersection, there are if-clauses to postprocess the result of GEOSIntersection before returning, but if the GEOS geometry type is not implemented, it is silently returning [] (note that there is even a commented NotImplementedError call). I have recompiled the Cython extension uncommenting these lines and now I get the following error when reaching the Switzerland polygon:

NotImplementedError: intersections of type 'b'GeometryCollection'' not yet implemented

So your problem is coming from the incapability of the Cython interface to process GeometryCollection objects in BaseGeometry.intersection and silently returning nothing.

One fast workaround below would be to check if geoms is empty, and then simply draw the whole polygon, because we know from poly.intersects(boundarypolyll) that geoms cannot be empty. The side effect is that some segments will be drawn outside the map boundaries, but they should still be clipped by matplotlib when plotting, unless the clipping mechanism is disabled on purpose (which is discouraged when working with basemap, because we do not want things drawn outside the map):

basemap/packages/basemap/src/mpl_toolkits/basemap/__init__.py

Lines 1371 to 1373 in c20c146

	if poly.intersects(boundarypolyll):
	if name != 'gshhs' or as_polygons:
	geoms = poly.intersection(boundarypolyll)

                            if poly.intersects(boundarypolyll):
                                if name != 'gshhs' or as_polygons:
                                    geoms = poly.intersection(boundarypolyll)
                                    if not geoms:
                                        geoms = [poly]

Of course the Cython interface still would need the real fix, but then I might not make it for basemap 1.3.9, which I wanted to release today or tomorrow. This is how your example looks like when I apply the patch in my local copy:

[molinav]

In the end, I fixed the source of the problem in _geoslib.pyx because it was not that complicated (at least to make it work with the simplest cases like the bug that you found). I will need to revisit _geoslib.pyx in the future, but for the 1.3.9 release I would say it is ok.

[molinav]

I have just released basemap 1.3.9 on PyPI and conda-forge, which includes the bugfix for the missing country borders. If there is still any problem on your side, feel free to reopen the issue.

[guidocioni]

@molinav thank you so much for this! I have to admit I haven't followed everything here but I'm glad you were able to find a solution for a long standing bug that I randomly discovered 😄

[guidocioni]

Hey @molinav , I'm trying to deploy this in production but having troubles updating basemap with conda.

I tried to update it but it wouldn't let me, then I tried to install the specific version and I'm getting these incompatibilities. However, it seems that there is always a good candidate so I'm not sure where the incompatibility is coming from.
