I love the idea of syncing git commit history with data change history, like using git for a repo of data. It's actually quite possible if you use pretty printed JSON as a record format (or other simple linear text formats).
London has a surprising history and love for its trees, more so than I've seen in other cities I've lived in. This means you can find a lot of fun listicles that provide history and fun facts for trees located around the city.
Especially in the heat the difference trees make is incredible. Moving from a tree-lined street to an open one is horrible when walking around the place.
Not to one-up you, but Sheffield in South Yorkshire has even more trees. I visited recently and was taken aback by how much coverage there was for a city center, coming from Leeds, which seems to hate trees.
If I remember correctly, London has around 8.5 million trees (for a population of almost 9 million, 1:1 tree:person) and Sheffield has around 4.5 million (for a much smaller population of less than 600,000, 7.5:1 tree:person). Sheffield has more trees per person than any other city in Europe.
Sheffield council tried to cut down thousands of trees a few years ago and it caused massive backlash, protests and arrests.
A friend of mine is doing something similar to this London tree but another European capital. I really don't understand why would someone _not_ integrate or just expand opentrees.org.
what is the point of having two openlayers websites? (unless of course the second is esri world atlas...)
EDIT: Wondering about the distinct areas without trees on the island? Those are buroughs that look as though they don't report to the City of Montreal. In the case of Westmount, it's because they are a distinct city.
This is diverging from the topic of trees quite a bit, but as a frequent visitor to SG from northern Europe, I'm always blown away by the people who can manage to do manual labour in jeans there! While I'm sweating in shorts and a light t-shirt just walking from the MRT to my destination.
Interesting these maps are missing many trees such as the DC missing those around the the capital building. Presumably because different organizations are in charge of them.
There seem to be a lot of trees in the category "other". Is there more detailed data for species and variety in another database somewhere, or is there a need for a massive wiki-style tree-spotting data-gathering exercise? Could start now while they still have leaves on them and perhaps also fruit ...
A propos that, if you ask it to show just "Black Locust" and "Horse Chestnut", then nothing is shown. But those are common trees! And they are also the two whose names consist of two words. So I suspect a BUG!
As a slightly more frivolous use of this website - we're approaching conker season!
Last year my kids wanted to go collecting conkers and I used a similar website (https://www.treetalk.co.uk/) to find a local place with lots of horse chestnuts.
It worked brilliantly and the kids thought I was some kind of genius for finding so many.
> I'm amazed that such datasets exist. Don't know what's the purpose and who is managing this but it's jus absurd (in a good way)
A significant portion of London's trees are subject to Tree Preservation Orders (TPO) and/or are located in a conservation area.[1]
If you want to do anything to a tree subject to the above, then you in conjunction with your tree surgeon need to request permission from the local authority. If you don't then you're in trouble because it is a criminal offence to remove, prune or damage protected trees.
In addition you of course have non-protected trees on public land that are owned by the local authority and so they likely have a maintenance database for those.
So it therefore goes that you require a database of said trees and hence this dataset is likely nothing more than an aggregation of the indvidual datasets from the various local authorities (of which there are 32 IIRC, hence quite a lot of data).
Here is an example of a TPO list from just one Local Authority.[2]
I think, at least partially, "civil engineers" - good to know where trees are as an indication of potential root problems with pavements, pipes, conduits, etc. Also for things like "where might we have road overhang problems" - if it's a conifer, probably ok, but if it's a London Plane, that might be an issue.
Oh and also to know where to send the horrifically noisy leaf blowing man who spends half his life outside in the square revving his diesel abomination.
You're absolutely right. I think this is of trees that need checking and maintenance to keep roads, cars, pedestrians safe. Hence the URL /street_trees/
Parks and woods would be maintained in a different process. Obviously it's acceptable and even desirable to have fallen down trees in woods and some parks.
Trees on private property are also missing — in front of people's houses/communal areas in front of blocks of flats. There's quite a few of those around me that I would consider to be "street trees".
I've checked my local area, and already spotted more mistakes and omissions than correct tree markers. Not saying it as a complaint - there are so many more trees here than specified in the map, I bet the map only shows about 20-30%.
This is specifically the council. Local resident care an awful lot about their trees and there are many local campaigns to make sure something like that doesn’t happen again. I think the local labour party ended up replacing some of the MP’s involved. (I live in Sheffield)

For example, [Great Trees of London](https://londonist.com/london/maps/great-trees-of-london-map) has a collection I'd actually enjoy walking around, and coupling with other sites in the area.

Since the protests, the council stopped cutting the trees down and reversed course.
Sheffield has more trees per person than any other city in Europe. Around 4.5 million trees for a population of 600,000 (7.5:1).
