[jayavenkatesh19]

The follow elements have to be added to the notebook to make it more non-GIS user friendly.

• Environment creation and requirements specification
• Further explanation about CRS and difference between using EPSG codes like 4326 etc
• A markdown cell describing how to create your own AOI on an online GeoJSON tool such as geojson.io
• A markdown cell describing hardware details and timing charts (can reuse the same ones from the PyData Boston talk)
