Ghana Data Stuff

Ghana Data Stuff

Welcome

Welcome on the website “Ghana Data Stuff”. This is a portfolio website I built to showcase some of the side projects I am working on at night, while working on more ‘official’ statistics for Ghana during the day. The original name of this project was “Ghana Data Science”, but then I realized that I do not really want to do any science. I just want to play with data a bit, hence the name “Ghana Data Stuff”. This also means that I will try not to do the same type of project more than once or twice. For every post, I will challenge myself to use a new technique, R Package, Python Library, coding language or other skill. I will then write out a little walk-through documenting my work flow. So, the posts on this website are not detailed tutorials, but should be sufficiently documented for readers to replicate the results for themselves. If you have any good ideas for a project, let me know and we can work on it together.

So to clarify, nothing on this website should serve an ‘official’ statistic or even be interpreted as being reliable or verified.

Finding the Greenest Neigbourhood in Accra Using Open-source Satellite Sentinel-2 NDVI Data

This walkthrough shows you how to download multispectral satellite (sentinel-2) in R, calculate the NDVI, create spatial statistics for different neighbourhoods using shapefiles, and plot the results. Spoiler: the University of Ghana Campus is the greenest neigbourhood in Accra.
