Catalunya Lego map

I stumbled upon a lego map in twitter and I thought it was quite fun and I should do something similar:

And here’s the result. One with NaturalEarth data colours for height, and another one with a set of official lego colours πŸ˜€

NOTE from the future:
Since everybody in twitter was to keen to remind me, First the map in EPSG:25831, then in 4236 πŸ˜€

The Way of Kings

I went into this because there were so many good reviews of it and I was looking for a holiday book. The summary and the cover were not very amusing, and it being a 1200 pages novel did not help either. But I finally decided to give it a go, what else to do two weeks while camping?

It wasn’t only hype, this is really good entertainment. Mr Sanderson knows how to tell good stories within in an interestingly built world. That’s all there’s to say, if you like fantasy books this one is a must. And I’m hooked into buying the second part of the story (if that’s an indicative of how much I liked it).

Be warned though, you’re in for a slow burn. A set of stories and small backdrop pieces set up the world and present it from various point of views: A naive young noble with a disgraced family, a surgeon apprentice turned soldier and fallen into slavery, and finally, the classic portrait of a ruler who has a very strict view of honour. Those three are the bulk of the book, sprinkled with an assassin, a fisherman on a remote land, the young king and etcetera.

Compared to other fantasy like Game of Thrones it is a very tame book. Yes, there’s war, there are assassins, some characters get tortured one way or another, some fall in love, a lot die… but it feels like a book a younger audience could also enjoy. Lots of mystery, fights, special powers, plot turns… I would not be surprised if the story is pitched in the future for a Hollywood adaptation.

On the things I did not like… I’m not a fan on how the drawings and pictures are treated in my edition (Spanish 6th edition). The original art tries to give the feeling of an old parchment. In my print it does not look convincing, and to add to the injury the translation on top of the images uses a regular font instead of giving it a manual treatment, it falls too hard into the faux parchment area for my taste. There are also some mismatches between the country names in the map and in the text… nothing that detracts from the book, but looks cheap for such a huge and expensive novel.

As a closing, I like this post of Patrick Rothfuss about the way of kings πŸ˜€

Totally recommended!

Coming back with another bcn map. this time I’m not representing anything from open data, but I’m playing around the network analysis tool available with Qgis. The following distances map has been generated using those tools:

Barcelona unemployment evolution 2012-2019

Coat of Arms Barcelona

Keeping with the row of Barcelona data, I present here a map of the unemployment rate per neighbourhood since 2012 up to 2019.

The data comes from Barcelona open data estat-atur-pes dataset. This dataset contains the column pes_atur for each month of each year. In the presented visualizations I simply used the value of January for each year.

pes_atur is the percentage of the unemployed registered citizens in each neighbourhood over the number of registered citizens for that neighbourhood with ages comprised between 16 and 64 years old.

Long definition, but clear idea.

Again, using a choropleth map similar to the one from the mean rent prices map. I just used a different colour scheme from white (almost no unemployment) to red (heavy unemployment).

First an animated gif of all the maps:

And now, all the individual maps per year.

There was no data prior to 2012, so what we can mostly see from here is a kind of recovery from the 2009 financial crisis. We come from 2012 when most neighbourhoods had over 11% of registered unemployment, to 2019 when we can see lighter tones, showing unemployment rates under 9% in most areas.

This is clearly not an in-depth review, just a quick take on the presented data. More information can be seen in the official Barcelona website, or the small publications from newspapers.

Barcelona trees

Coat of Arms Barcelona


Here I am again, this time with something that I love, trees!

It’s mostly common knowledge that the tree of Barcelona is the Platanus (bear with me with tree names, since the names in english confuse me most of the time πŸ™‚ ). I’ve been looking for an excuse to dive back to Barcelona open data, and to create a hex-grid-map.

For this two images, I’ve used the street trees dataset, which only takes into account trees planted along streets, parks and green zones are not taken into account.

And from this excuse, two new data visualizations emerged!

show me those trees
