flask-folium-app

By developing this app, we wished to accomplish the following:

1. Create a version 1 of an interactive well map with Folium.

2. Gain experience with the full path from a Jupyter Notebook, to a Flask app, to deployment.

PLEASE NOTE: the app is not presently online due to costs. We have deployed this app on DigitalOcean during a limited time to test it. This repo contains all necessary files for deployment.

Project description

The well data map shows the position of all exploration wellbores on the Norwegian shelf. Wellbores are grouped into clusters when zooming out. By clicking on a wellbore position, a popup comes up with additional information.

Stack: Folium, Flask (Flask-wtf, Flask-mail), Bootstrap, Docker..

Additionally, there is a contact form where users can contact us with comments/suggestions.

Data

The dataset is in the form of a shapefile which is publicly hosted by the Norwegian Petroleum Directorate, here.

Future developments

• Add map functionalites and features (solve display slowness issues for polygons)

Jupyter notebook to WebApp pipeline

Note: this pipeline is one of the many possibilities how to transform a Jupyter notebook into a web app, and deploy it. There are many other solutions. Here is the main steps we follow:

• open Jupyter notebook in Visual Studio Code. Clean the code (cells, comments, etc). Add functions.
• create file structure for Flask app (app.py, templates, static)
• add bootstrap for UI design
• add button and menu functionalities (UI/UX)
• create contact form with Flask-WTF and Flask-mail
• testing and more testing on localhost
• create requirements.txt
• create DOCKERFILE
• create github repo for web app files
• add a new project and droplet on DigitalOcean
• set up SSH access on remote
• clone repo on remote
• create DOCKER container on remote
• LAUNCH APP!
