OSM Tiles

Load OSM data into Postgis

Step one of this process seems to be 'osm2pgsql'

https://osm2pgsql.org/

git clone git://github.com/openstreetmap/osm2pgsql.git

osm2pgsql docs: https://osm2pgsql.org/doc/manual.html

Dependencies (replace XX with the appropriate version #s):

sudo apt install postgresql-XX postgresql-XX-postgis-XX postgresql-contrib
sudo apt install make cmake g++ libboost-dev libboost-system-dev \
  libboost-filesystem-dev libexpat1-dev zlib1g-dev \
  libbz2-dev libpq-dev libproj-dev lua5.3 liblua5.3-dev pandoc

Build:

mkdir build
cd build
cmake ..
make
make man
sudo make install

Set up Postgresql (https://osm2pgsql.org/doc/manual.html#preparing-the-database):

# this assumes you want things in a database named 'osm' that your current user role has permissions for
sudo -u postgres createdb --encoding=UTF8 osm
postgres psql osm --command='CREATE EXTENSION postgis;'
postgres psql osm --command='CREATE EXTENSION hstore;'

There is additional tuning guidance here: https://osm2pgsql.org/doc/manual.html#preparing-the-database

List of OSM repositories:

https://wiki.openstreetmap.org/wiki/Planet.osm

Shape files by region available here:

https://download.geofabrik.de/

(either way, you're looking for the PBF file)

Do the load (again, assuming database osm):

osm2pgsql [[data_file.osm.pbf]] -d osm

Map Data Rendering

The tool used here seems to be Mapnik: https://mapnik.org/

Install easy Mapnik dependencies

sudo apt install libharfbuzz-dev libboost-regex-dev libboost-program-options-dev libcairo2-dev libgdal-dev

Mapnik also relies on ICU (unicode support)

Download here: https://github.com/unicode-org/icu/releases/
Several precompiled releases are available. Untarball and put the icu directory in the mapnik directory

Finally, Mapnik relies on (ugh) python 2.7. This is probably going to cause bit-rot on these instructions, but for now installing python2.7 with pyenv seems to work:

git clone https://github.com/pyenv/pyenv.git ~/.pyenv
cd ~/.pyenv && src/configure && make -C src
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bash_profile
source ~/.bash_profile
sudo apt-get install -y build-essential libssl-dev zlib1g-dev libbz2-dev \
  libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
  xz-utils tk-dev libffi-dev liblzma-dev python-openssl git
pyenv install 2.7.18

Finally download mapnik and install it (as of the time of writing, the python bindings were incompatible with the main branch):

cd mapnik
pyenv local 2.7.18
git checkout v3.0.x
./configure
make

Installing is tricky, since pyenv and sudo don't play nice.

sudo bash
PATH=$PATH:~[[YOUR_USERNAME_HERE]]/.pyenv/shims
make install

It looks like there's some extra style information

sudo apt install subversion unzip
svn co http://svn.openstreetmap.org/applications/rendering/mapnik mapnik-style
cd mapnik-style
./get-coastlines.sh

sudo apt install libboost-python-dev libboost-thread-dev
