Plenar.io

API for geospatial and time aggregation across multiple open datasets.

This project is funded by the NSF Computer and Information Science and Engineering (CISE) Directorate through a grant to the Urban Center for Computation and Data (UrbanCCD) at the Computation Institute of the University of Chicago and Argonne National Laboratory. It is maintained by UrbanCCD and was prototyped by DataMade.

Development Information

We are currently developing the next version of Plenario. Information regarding the build process and other information can found at https://github.com/UrbanCCD-UChicago/plenario-platform/wiki.

Running locally with Docker

To maximize development portability, we use Docker and Docker Compose. To build and run the Plenario application using docker, do the following:

$ docker-compose build  # will spew out tons of debug logs while building containers
$ docker-compose up     # will also produce tons of verbose logs

Once the server is running, navigate to http://localhost:5000/ . From the homepage, click 'Login' to log in with the username and password from settings.py. Once logged in, go to 'Add a dataset' under the 'Admin' menu to add your own datasets.

Developing with Docker

When you make code changes, you must reload the containers:

$ ^C                    # kill the running containers with Ctrl-C
$ docker-compose down   # ensure it's all down and ready to be rebuilt
$ docker-compose build  # rebuild them to load the changes and install anything new
$ docker-compose up     # restart the containers

Running locally

Get the Plenario source:

git clone [email protected]:UrbanCCD-UChicago/plenario.git

Install support libraries for Python:

cd plenario
pip install -r requirements.txt

If you aren't already running PostgreSQL, we recommend installing version 9.3 or later.

Make sure the host of your database has the PostGIS extension installed.

The following command creates a postgres database, imports the plv8 and postgis extensions, and creates all the necessary tables for plenario to work. The database name corresponds with the DB_NAME setting in your plenario/settings.py file and can be modified. It will be set to plenario_test by default.

./manage.py init

You'll need the ogr2ogr utility - part of the gdal package. We use it to import and export shape datasets.

OSX

brew install gdal --with-postgresql

Ubuntu/Debian

sudo apt-get install gdal-bin

The default settings should work given a typical postgres setup, however should you find that the init method fails to run - the first place to check would be the settings.py file.

You will likely want to change, at minimum, the following settings.py fields:

• DATABASE_CONN: edit this field to reflect your PostgreSQL username, server hostname, port, and database name.

• DEFAULT_USER: change the username, email and password on the administrator account you will use on Plenario locally.

Before running the server, Redis needs to be running.

• To start Redis locally (in the background):

redis-server &

Start up a worker:

./manage.py worker

Finally, run the server:

./manage.py runserver

Once the server is running, navigate to http://localhost:5000/ . From the homepage, click 'Login' to log in with the username and password from settings.py. Once logged in, go to 'Add a dataset' under the 'Admin' menu to add your own datasets.
