1. Install PostgreSQL and PostGIS:

• Ubuntu:

  sudo apt-get install postgresql-9.3
  sudo apt-get install postgresql-9.3-postgis-2.1
  sudo apt-get install postgresql-server-dev-9.3
  

• OS X

  Easiest way is to download and install the postregapp. Download PostgreSQL 9.3 with PostGIS 2.1 and copy the app to your /Applications folder.

2. Create database and enable postgis:

sudo -u postgres psql
> CREATE DATABASE gis;
> \connect gis
> CREATE EXTENSION postgis;

Note: Mac users who have downloaded the postgres.app might have to mind the username passed with -u in the command above. The user postgres(which is default in many postgres installations) might not be present. The postgres.app will create an user with the same username as a your OS X's username as default user. So use your OS X's username instead of postgres

3. Miniconda Download and install miniconda package, containing conda package manager and Anaconda distribution of Python. (Use Python version 3.4)

• Ubuntu

  wget http://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
  chmod +x Miniconda3-latest-Linux-x86_64.sh
  ./Miniconda3-latest-Linux-x86_64.sh
  

  follow the instructions of the installation process.

• OS X

  Download and run the Anaconda3-2.3.0-MacOSX-x86_64.pkg installer from https://repo.continuum.io/archive/index.html which contains the correct python version(which is 3.4) we use for the project.

4. Create a virtual environment for the project:

   conda create -n pgisenv anaconda python=3.4.1
   

5. Clone the repository:

   git clone git@github.com:OpenGridMap/pgis.git
   cd pgis/
   

6. Setup database and other application variables: Copy database.yml.example and application.yml.example to database.yml and application.yml and edit them to match your configuration:

   cp database.yml.example database.yml
   cp application.yml.example application.yml

   Now, edit database.yml and application.yml to match your configuration.

7. Activate virtual environment:

   source activate pgisenv
   

8. Install Python dependencies:

   pip install -r requirements.txt
   

9. Run migrations:

   ./manage db upgrade
   

10. Install nodejs, npm (Used by less asset compiler) and less:

sudo apt-get install nodejs
ln -s /usr/bin/nodejs /usr/bin/node
sudo apt-get install npm
sudo npm install -g less

11. Install kmeans clustering extension for Postgis:

• Ubuntu:

  wget http://api.pgxn.org/dist/kmeans/1.1.0/kmeans-1.1.0.zip
  unzip kmeans-1.1.0.zip
  cd kmeans-1.1.0/
  export USE_PGXS=1  # in bash
  
  make
  make install
  psql -f /usr/share/postgresql/9.3/extension/kmeans.sql -U postgres -d gis
  

• OS X

  • Download and unzip http://api.pgxn.org/dist/kmeans/1.1.0/kmeans-1.1.0.zip then

    cd kmeans-1.1.0/
    export USE_PGXS=1  # in bash
    
    make
    make install  # note the output and find the location where the kmeans.sql extension is being installed
    

  • From make install note the location where the kmeans.sql extension is being installed. If you have installed postgres via the postgres.app, the installation location is most likely to be /Applications/Postgres.app/Contents/Versions/<your version>/share/postgresql/extension/.

  • With the location, run the command below

    psql -f /Applications/Postgres.app/Contents/Versions/<yourVersion>/share/postgresql/extension/kmeans.sql -U postgres -d gis
    

    Note: postgres is the username passed to the -U option. Use the right username based on your postgres installation.

With a built-in server (not ok for production):

./manage runserver

for production:

gunicorn app:GisApp --bind localhost:3000

Or to run in production with PM2:

pm2 start rerun_pgis.js --name rerun_pgis
pm2 start run_import_schedule.js --name import_transnet
sudo pm2 start rerun_nginx.js --name rerun_nginx_2
cd generator_app/
pm2 start check_run_pgis_gen.js --name main_pgin_generator
sudo pm2 startup

• Download OSM data file from http://download.geofabrik.de/.

• import_osm_data.py script is used to import the data. However, it needs to run with Python 2.* not Python 3. So deactivate the virtual environment from ananconda that we installed(it has Python 3) and run with the default Python on your host machine. To verify whether you have the right version, run python --version and see of it is Python 2.

• Once you have right python version you will need to install few dependancies to run this import script.

  • Protocol Buffers

    • On Ubuntu:

      sudo apt-get install -y python-pip python-dev
      wget https://github.com/google/protobuf/releases/download/v2.6.0/protobuf-2.6.0.tar.gz
      tar xvfz protobuf-2.6.0.tar.gz
      cd protobuf-2.6.0
      sudo ./configure
      sudo make install

    • OS X

      Haven't really tested this command. Please let us know if this doesn't work

      brew install protobuf

  • Python libraries: imposm.parserand psycopg2. Installed using pip.

    Note: On Ubuntu, you may possibly face the following error while running these commands:

     protoc: error while loading shared libraries: libprotoc.so.9: cannot open shared object file: No such file or directory`
    

    To overcome this, do the following before running the command that caused the error.

    export LD_LIBRARY_PATH=/usr/local/lib`

    The commands to install the libraries/packages is same on both OS X and Ubuntu.

    pip install imposm.parser
    pip install psycopg2

    If you get any Permissions Erorr, try to use the --user(see below) to install only for the active user.

    pip install --user imposm.parser # Only if you have Permission Error
    pip install --user psycopg2 # Only if you have Permission Error

• Import

  Once you have the above steps completed, you may import the data from the OSM data files(*.pbf):

  cd pgis
  python import_osm_data.py europe-latest.osm.pbf

• During pip install -r requirements.txt
  • Generic:
  • If you face any issue during this stage, the best thing to do is to match the error to those that are below. If you do not find instructions about it here, your best move should be to find which library or package is failing and try to install it seperately. * Find the version required from the requirements.txt of that library/package that is failing and install it with conda install <package>=<version>
  • Library not loaded: libcrypto.1.0.0.dylib while installing cryptography
    • in the active bash session, do export DYLD_LIBRARY_PATH=$HOME/anaconda/lib and re-run the command in then same bash session.
    • If you use a different bash session, the environmental variable will be lost. If you want this to be present in any future bash session, add the export line to your .bashrc or .bash_profile file.
  • Error: could not invoke ['llvm-config', '--version']
    • you need to install llvmpy on your conda env. According to the requirement.txt file, you need the version 0.12.7. You can install it with conda install -c https://conda.anaconda.org/sklam llvmpy=0.12.7.
    • From the command, you install llvmpy from sklam's repo instead of the usual anaconda's repo. You could also install from anaconda directly by conda install llvmpy=0.12.7. I installed sklam`s version because the other failed.
  • Error: pg_config executable not found.
    • Check the postgresql installation on your host computer. Find the pg_config executable path and append it to your PATH environmental variable.
    • If you have downlaoded and use postgres.app on your mac as in the installation instructions section, locate the pg_config executable in /Applications/Postgres.app/Contents/Versions/<your version>/bin and update your PATH environmental variable.
  • ValueError: unknown locale: UTF-8
    • Follow the instructions http://conda.pydata.org/docs/troubleshooting.html#unknown-locale
  • ld: library not found for -lhdf5
    • you need to set an environment variable for this too. Do export HDF5_DIR=$HOME/anaconda/lib in the current bash session and re-run the command in then same bash session.
    • If you use a different bash session, the environmental variable will be lost. If you want this to be present in any future bash session, add the export line to your .bashrc or .bash_profile file.
  • error: no member named 'f_tstate' in 'struct _frame'
  • Check which package was being tried to be installed while this error happened, it might be Cython. check the version for that package from requirement.txt file and do conda install cython=0.211. Change the package name and version based on your need.
  • Found existing installation: Sphinx 1.3.1 or Cannot remove entries from nonexistent file /Users/Munna/anaconda/lib/python3.4/site-packages/easy-install.pth
    • This happens when there is a Sphinx installation already, find the version that is needed from the required from requirements.txt file and install that using conda install sphinx=<version>
• During ./manage db migrate
  • ImportError: No module named 'flask_resize'
    • Do pip install flask-resize
  • Library not loaded
    • Run the following
      • sudo ln -s ~/anaconda/lib/libcrypto.1.0.0.dylib /usr/local/lib/ (try /usr/lib, if it says operation not permitted even with sudo, do /usr/local/lib)
      • sudo ln -s ~/anaconda/lib/libssl.1.0.0.dylib /usr/local/lib/ (try /usr/lib, if it says operation not permitted even with sudo, do /usr/local/lib)
