Janaganana

Janaganana is a Django application for exploring census and other similar data. Counting India is a sample application developed using Janaganana and is maintained by Factly. Janaganana is most suited for census data but it can be used easily with any other similar data.

Janaganana has been modeled on tools like Wazimap Kenya, Census Reporter and as inspired by NepalMap.

Counting India

Counting India (CI) is an initiative of Factly. CI makes data related to the States/Districts in India more accessible and understandable. The primary source of data for CI is the Census of India 2011 and other official sources. In CI, one can compare any two States/Districts side by side. One can also embed, access or download the data.

We envision that every person who is interested in using data in their sphere of work will value CI’s platform. CI will also be a reliable resource for policy makers, journalists and researchers to explore and discover stories of public interest in India.

Currently we are on a Beta version of CI and are actively working on fixing the defects for our first stable version. Please email us with any findings or defects that you would like to bring to our notice.

CI code is licensed under the MIT License. Anyone could host their own instance of CI by following the installation guide. Credit to Factly, Janganana would be highly appreciated and please inform us about how you are using it.

Production Installation for Counting India

Following set-up is a quick installation for Counting India in production which includes Nginx proxy and a free Let'sEncrypt SSL certificate using Certbot. The steps also includes automatic renewal of the certificates!!

Pre-requisites

• A Linux server with DNS mapped to the server IP address
• Install Docker
• Install Docker Compose

Setting up for Nginx and Certbot

• Clone the repository and make sure Docker is running

• Create an .env file with the following params and change the values appropriately

  DJANGO_SECRET_KEY='YOUR-SECRET-KEY'
  

• Change the values in the nginx/default.conf from countingindia.com to your domain name

• Change the domains in init-letsencrypt.sh from countingindia.com to your domain names

• Setup nginx and certbot by executing the following command

  sudo ./init-letsencrypt.sh
  

  If the DNS mappings are correct and the prior steps are followed correctly, the above script issues a temporary certificate to start nginx and then issues the original certificates for your domain name after nginx is started.

• Bring down the entire application after the certificates are issued as expected using the following command

  docker-compose down
  

Running the application

• Make sure Docker is running and execute the following command to run the application

  docker-compose up
  

• It will take a few min to load up the database and install all the required census data into the database. Once the application is started you should be able to access it on your domain name.
