**Exploring shapefile options**
I’m considering using Cartopy, which can be heavy and needs GEOS/PROJ compiled.
Geopandas also requires these, but maybe we can find wheels in many environments
. If access is restricted, I could use escalated permissions to download wheels.
Another option is Fiona/GDAL, though it can be tricky. Maybe shapely, pyproj, o
r pyogrio could read shapefiles. Cartopy’s shapereader can automatically downloa
d Natural Earth shapefiles, but that could be heavy too. I’ll evaluate the best
method to read shapefiles effectively.**Clarifying projection details**
Using geopandas is the simplest route, assuming the wheels are available. I need
to reproject to EPSG:3035, which is defined with a center at lon=10, lat=52. Ho
wever, the user specified lon=15, lat=55, creating a mismatch. It seems they wan
t a custom LAEA projection, so I can create a custom string: '+proj=laea +lat_0=
55 +lon_0=15 +datum=WGS84 +units=m +no_defs'. We’ll follow the user's specificat
ions while noting this isn’t the standard EPSG:3035. I also need to clip Russia’
s geometry at lon=60.**Planning clipping procedures**
I plan to clip in geographic coordinates (EPSG:4326) by creating a polygon that
covers longitudes up to 60 and latitudes from -90 to 90. Using a shapely box wit
h min and max values makes sense. Then, I'll intersect this with Russia’s geomet
ry. For Turkey, I want to clip the European Thrace region, which is west of the
Bosphorus, around lon < 29E. Using the Natural Earth 'Europe' region might help,
but I could also approximate around 29.2E and north of 40N. This may not be str
aightforward, though!**Setting clipping parameters for Turkey**
Natural Earth admin 0 gives us a 'continent' field, but it's unclear if Turkey i
s classified as part of Asia or Europe. It seems simpler to create a polygon to
clip approximately west of 28.3E. However, since the specification mentions "Eur
opean Thrace," I'll create a polygon based on that. I can clip the area by choos
ing lon<29.2 to encompass the European part, including Istanbul, which is around
28.97-28.99. So I’ll set the clip at 29.15E, ensuring we account for Cyprus in
the inset.**Creating a multi-step plan for mapping**
I’m focusing on including Cyprus, Malta, Iceland, and various microstates in the
Eastern Mediterranean. I’ll create an inset axis for these regions, adding anno
tation arrows and ensuring labels avoid overlaps. The background will be light w
ith thin gray coastlines, possibly from Natural Earth, and I’ll select a color-b
lind safe palette like ColorBrewer 'Set2' or 'tab20'.
To process and plot, I’ll set up a virtual environment, install required package
s, and download the necessary Natural Earth data using `curl` before running the
mapping script. I’ll ensure to create detailed insets and validate the final ou
tputs thoroughly.**Planning the mapping process**
I’m setting up to run shell commands like creating a virtual environment and ins
talling necessary packages. I’ll download Natural Earth data into a designated d
irectory using `curl`.
The plan includes reading shapefiles with geopandas, mapping country names to Na
tural Earth names, and creating synthetic entries for the European parts of Russ
ia and Turkey. I’ll incorporate Cyprus in an inset while reprojecting all geomet
ries as needed. Labels must be non-overlapping, using `adjustText`, and I’ll ens
ure all disputed areas are marked accurately. Finally, I’ll perform checks to ve
rify counts and label visibility before saving the outputs.

**Writing Python script**
I’m starting to write a Python script called `map_europe.py`. The main task is t
o programmatically process a list of 47 countries, which sounds interesting! I’l
l need to create a mapping to their respective NE (named entity) names. This app
roach should help streamline the process and make it more efficient. Let's see h
ow this unfolds as I outline the rest of the steps!**Listing countries for mappi
ng**
I'm compiling a list of European countries to process, and it's quite a lengthy
one! It includes Albania, Andorra, Austria, Belarus, Belgium, and many more, tot
aling 47 in all. Now, I need to map the named entity (NE) names. For example, "B
osnia and Herzegovina" might be shortened to "Bosnia and Herz." in some uses, wh
ile "NAME_EN" would typically include the full name. It's interesting to see the
variations that exist!**Mapping NE names for countries**
I’m deciding to use 'NAME_EN' where it exists for each country. For some microst
ates, names like "Czechia," "North Macedonia," and "United Kingdom" are straight
forward. However, "Vatican City" might also be known as "Holy See." When process
ing the shapefile, I need to filter by 'SOVEREIGNT' or 'NAME_EN.' Some countries
have territories, but I only want to focus on the main parts, like the "United
Kingdom." I'll implement a function to clip Russia and Turkey accordingly.**Proc
essing geometries for Russia and Turkey**
I’m focusing on processing the geometries for Russia and Turkey. For Russia, I’l
l intersect the geometry with longitude less than or equal to 60, and for Turkey
, I’ll intersect it with longitude less than or equal to 29.2 and an undefined l
atitude limit. The European part of Turkey lies west of the Bosporus and Dardane
lles. After that, I'll create a GeoDataFrame for the selected countries, adjusti
ng the names for both Russia and Turkey to specify their European parts. I’ll se
t up the projection using pyproj and plot it with Matplotlib!**Creating visualiz
ations for the map**
I’m working on visualizing 47 countries using color palettes like tab20, tab20b,
and tab20c to ensure we have enough colors. To annotate the map, I’ll get repre
sentative points from the geometry and label them, considering microstates and i
slands for special placements. I’ll either use callouts or insets for clarity, e
nsuring no overlaps by using adjustText. For disputed borders, I’ll plot dashed
lines, and we’ll check our country count and label visibility to ensure accuracy
. Finally, I’ll organize the script into functions for clarity!

I'm running the script now using the virtual environment. It should load properl
y, but there's a possibility of failure if there are issues with the geopandas e
ngine while reading the shapefile. I installed pyogrio and shapely 2, so I'm fee
ling hopeful that it will work smoothly. Let's see what happens next; I’ll keep
my fingers crossed that everything goes without a hitch!
