This typographic map shows the street trees in greater London. As Google didn’t give lot of information about the main tree species in all 32 (+city) boroughs I had to dig a little deeper and luckily found an incredible 700 000 list of street trees in London Tree Map website. None of my own tools was able to open the giant file, so I downloaded Tableau Public to check out, if there is a way to analyse this tree data. 🌳
I haven’t used Tableau before and turned out it was easier that I expected. It loaded amazingly quickly (considering the size of the file) and felt really intuitive to use. After setting couple of parameters I ended up with a funky table showing me the number of trees by species in boroughs. It even highlighted the values by colour which made it easier to follow. Magic! 💫
My next step was to sketch out the map based on data. Unfortunately the information for 7 boroughs are missing from the list, but I was still able to fill out most of the map. As the information is 4-5 years old, there might be some new developments, which I might be able to fill in later. Hoping to get some valuable information from experts on Twitter. 🤞
The pre-work done I found an open vector base map of greater London, which I modified slightly, and started to fill in the map digitally. This was straightforward but time consuming task and took me most of the second day to fill out the whole map. I decided to go with primary green colour to keep it clean and fresh. 🍃
After letting the map settle for a night I returned to it in the morning with fresh eyes to make some final fixes and adjustments. 👀
And here it is – the type map of London Street Trees by each borough.
