You can print any country with asciimap for which a Geometry exists (currently
177 countries). In general printing is pretty fast though big countries like
USA, Russia, Canada etc. need some extra computation time. To circumvent loading
times store the results in a database or similar. Disk space isn't much for
normal 40x80 sized ascii maps.
Dependencies
You need the python bindings for GDAL and GDAL itself installed. I experienced problems installing the python bindings into a virtualenv, so I recommend installing the system packages.
Arch
pacman -Sy gdal python-gdal
Debian/Ubuntu
apt-get update
apt-get install gdal-bin libgdal-dev python3-gdal
Installation
PyPi
Installation with pip is straightforward:
sudo pip install asciimap
Git
Installation with git from master branch:
git clone git@github.com:MaelStor/asciimap.git
cd asciimap
git checkout master
In userspace
Install in user space with:
pip install --user .

You can print a country looking like a negative with
$ asciimap --surface 1 fr --negative
..............................**................................................ ............................ ............................................... ............................ ............................................ ........................... ........................................... ........................... ......................................... ........................ . ..................................... ............ ........ ................................... ............ ... ................................. ............. .............................. ............. ........................ .... ..... ....................... * ........................ | ........................ | ......................... * ......................... .... ......................... ........ . .......................... ......... ............................ ........... .............................. ............ ............................... ............. ................................ .............. ................................ ............... ............................. ............... ............................ ............... ............................ ............... ............................ ............... ........................... ............... ............................ ............... ............................ ............... ............................ ............... ............................ ............... ........................... .............. ......................... .............. ......................... ............. .......................... ............. .... ............................ .............. ............................................ ................. ............................ ................ ..................... .. .......................... ................ .......France...............*----*..........................*--*................
or if you want the borders showed:
$ asciimap --surface 1 --outside '.' fr
..............................**................................................ ............................*/ \............................................... ............................/ *-*............................................ ...........................* \........................................... ...........................* **......................................... ........................*-* \.**..................................... ............*........*-* * **................................... ............*-*...*-* **................................. .............| *-* *-*.............................. .............| *----*........................ ....*--*.....* *....................... *--* *---* *........................ | *........................ | *......................... *--* |......................... ....*--* * *......................... ........\ *.**.......................... .........** **............................ ...........\ /.............................. ............\ /............................... .............\ *................................ ..............\ *................................ ...............* *-*............................. ...............| *............................ ...............| |............................ ...............| *............................ ...............| *........................... ...............| *............................ ...............| |............................ ...............| |............................ ...............| *............................ ...............* \........................... ..............* \*......................... ..............* *......................... .............* *--* **.......................... .............* *--*....*------*............................ ..............*-* /............................................ .................*--* ** *............................*................ .....................**..*-* *..........................*-|................ .......France...............*----*..........................*--*................
Fillings can be combined. If you want to fill the land surface with .,
everything outside the land surface with ~ and corners with ^ use:
$ asciimap nz --outside '~' --empty '.' --fill '^'

Advanced usage
Some advanced usage with command-line tools. The picture in the title was produced with
$ asciimap gb --height 30 --width 31 | paste - <(asciimap gb --height 30 --width 31 --fill "$") | paste - <(asciimap gb --height 30 --width 31 --fill "'")
another example with 'paste' and usage of 'blur':
$ asciimap -b 0 jp -i 30 -w 30 | paste - <(asciimap -b 2.0 jp -i 30 -w 30)

Sometimes a country has more than one land surface (or more precise: Polygons) defined, what scrambles the surface of interest when printing all surfaces:
$ asciimap --surface all --method full ru --fill "'"
' '
'
'
''
' '' ' '
' / |
' ' ' '
' ' '--' |
' |-' \ '\
\ | ' '' \'
\ |/ \ '
'' '-| ' '-' '
' \' '' \ ' |
|' \ / ' |
'| ' / |
' |/ |
| |
| '
' Russia ' /
' / ''
| '-'
| ' '
| | |
' ' |
' ' ' |
' | / ' ' |
| ' ' ' \ '
' ' ' \ ' ' '
' ' ' \ ' ' | | '
' ' ' ' \ /' | '
' ' ' ' |
| \|
'' |
/ | |
' ' '
'-' '
\' '
|
'
To overcome the bias you can just render the big land surface for example with:
$ asciimap --surface 1 --method height ru --fill "'"
'----' ''
'----' '--------' |
'--' '--' |
/-' '----' |
'-| '--' ' / |
'' | / \ ' '---' |
'--' '' ' | |
\ | ' |
'-------' '---' ' | ' |
| '--' '-' '---------' '-' '\ ' |
' '-' ' /\ '-' ' / |
' ' '--' '' '-' ' / |
| ' '' ' |
| ' '-' |
' '-' |
' |
/ Russia|
'' |
' |
'/ |
' |
\ |
'-' |
\ '----' |
'\ '---' '-----' |
\ ' \ |
'-\ '' | \ /|
\ '' '-----' ' '---' / '
'--' '' ' '' '-------'
\ / '--' '
' '
' \
/ \
/ ''
'----' /
'-' /
'---' \
'-'
'
what cuts off the eastern part of Russia. To print the whole surface:
$ asciimap --surface 1 --method width --height 20 ru --fill "'"
'-'
'' / '-'
'' '------' \
'' '' '-' '-------' ''
'\ ' | '-' '----' '------'
'--' \ '' /' / '---' '---'
| '-' ' '---' ' '-' / ' |
' / '' ' ' |
/ '-' ' ' '--'
/ Russia ' / \ '---'
' '---' '' /
'\ '' '-'
\ '----' ' ' ' |
\ ' / ' \ ' '-' '' ' '-'
'' '' '---' '-' '--' '--' '' / \ /|
' ' '-' '-' ' \ ' ' '
| ' ' \ '
' | ' |/
'--' '-'
'
To find the right surface you have to try around a bit. I'm working on a better solution.
Performance
Rendering time heavily depends on the count of Polygons and the size of the
resulting map. Printing a common sized country with 40x80 (h x w) usually
takes about 0.3 - 0.7 seconds on a 2-core system. Rendering is implemented to
use parallel processes and drastically reduces computation time on multicore
systems.
$ asciimap de --benchmark
parse_undefined_countries 0.0001 s _get_boundaries 0.0000 s __init__ 0.0007 s render_parallel 0.2032 s is_border 0.0440 s is_vertical 0.0034 s is_horizontal 0.0033 s is_negativ_diagonal 0.0032 s is_positiv_diagonal 0.0031 s print_map 0.0919 s ------------------------------------- Sum 0.3529 s
Bigger countries like USA, Russia, Canada etc. take a little more time.
Something between 0.7 - 1.5 seconds.
$ asciimap us -t
_get_boundaries 0.0001 s __init__ 0.0036 s render_parallel 0.6032 s is_border 0.0324 s is_vertical 0.0029 s is_horizontal 0.0028 s is_negativ_diagonal 0.0027 s is_positiv_diagonal 0.0027 s print_map 0.0697 s ------------------------------------- Sum 0.7200 s
You can run asciimap with --benchmark if you want to know execution times
of all used methods. Times for each method add up in case a method/function is
called multiple times.
