Tree Types of The World map

World map of tree types is crafted from data of more than 60 000 species recorded in the Botanic Gardens Conservation International database of all known tree spaces. The database is fluid and evolves as new information is recorded. I accessed the information on 22/09/2019 and although an attempt is made to include all the species on the graphic, some were excluded to achieve the aesthetic effect.

Working with more than 60 000 entries on the graphic has its own challenges that first involved cleaning up the data and converting it into importable text. Once I had the whopping 260 pages thread text file I placed it into graphics software on top of the contour of the world map and formatted as best as I could.. which was a slow going.

With font size of 12 pt a printed out version of this densely knitted type map would be legible covering about 3 metres by 2,5 metres wall…… Luckily the magic of digital version allows to zoom in the data to look for single entries! 💫

London Street Trees type map

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.
