Dr Balamurugan Soundararaj · Posted on December 29, 2017June 2, 2020

Recently I revisited work I did in 2012 (aosm.r)  where I made a function to extract features from OpenStreetMap data into R for plotting and analysis.

After trying to organise the reading for my research last week, I realised that research process in my mind is not organised as a list or a checklist but as a network of interconnected ideas from various sources.
