I signed up to take part in Leeds Creative Labs Summer 2014 programme with the hope that it would result in something interesting, something that a techie would never get the opportunity to do normally. It’s certainly exceeded that expectation – it’s been a fascinating enthralling process so far, and I feel honoured to have been selected to participate.
I’m the designated “technologist” who is in partnership with Dr Seán McLoughlin and Jo Merrygold on this project around The Hajj and British Muslims. Usually I tend to do geospatial collaborative and open data projects, although I’m also a member of the Leeds group of Psychogeographers. Psychogeography is intentionally vague to describe but one definition is that it’s about the feelings and effects of space and place on people. It’s also about a critique of space – a way to see how modern day consumerism/capitalism is changing how our spaces are, and by definition how we in these spaces behave.
We had our first meeting last week – it was a “show and tell” by Seán and Jo to share some of the ideas, research, themes and topics that could be of relevance to what we will be doing.
Show and tell
Seán, from the School of Philosophy, Religion and The History of Science introduced his research on Islam and Muslim culture, politics and society in contexts of contemporary migration, diaspora and transnationalism. In particular his work has been around and with South Asian heritage British Muslim communities. The current focus of his work, and the primary subject of this project is about researching British Muslim pilgrims’ experiences of the Hajj.
The main resources are audio interviews, transcripts and on-line questionnaires from a number of different sources such as pilgrims of all ages and backgrounds, other people related to the Hajj “industry” such as tour operators and charities.
Towards the end of the year are a few set days for the Hajj – a once in a lifetime pilgrimage to the holy Saudi Arabian city of Mecca. You have probably seen similar photos such as this where thousands of pilgrims circle the Kaaba – the sacred cuboid house right in the centre of the most sacred Muslim mosque.
It’s literally the most sacred point in Islam. It’s the focal point for prayers and thoughts. Muslims orient themselves towards this building when praying. The place is thought about everywhere – for example, people may have paintings with this building in their homes in the UK, and they may bring back souvenirs of their Hajj pilgrimage . You can see that the psychogeography of space and place on the emotions and thoughts of people could be very applicable here!
And yet the Hajj itself is more than just about the Kaaba – it’s a number of activities around the area. Here’s a map!
These activities, all with their own days and particular ways of doing them are literally meant to be in the footsteps of key religious figures in the past. I will let the interested reader to discover for themselves, but there’s a number of fascinating issues surrounding the Hajj for British Muslims with Seán outlined.
Here’s a small example of some of these themes:
Organising the Hajj (tour operators, travel etc).
What the personal experiences of the pilgrims were.
How Mecca has changed, and how the Hajj has changed.
The commercial, the profane, the everyday and the transcendent and the sacred.
How this particular location and event works over time and space.
What are the differences and similarity of people and cultures, and possible experiences of poverty.
“Hajj is not a holiday” and Hajj Ratings.
Differences in approach of modern British Muslims to going to the Hajj (compared to say their grandparents).
Returning home and the meaning and expectations of returnees (called Hajjis).
What we did and didn’t do
We didn’t rush to define our project outputs – but we all agreed that we wanted to produce something!
Echoing Maria’s post earlier we are trying to leave the options open for what we hope to do. Allowing our imaginations to run and to explore options. I think this justice to the concept of experimentation and collaboration, and should help us be more creative. I think that we can see which spark our imaginations, what address the issues better – what examples and existing things are out there that can be re-appropriated or borrowed, and which things point us in the right direction.
What I did after
So after the show and tell my mind was spinning with new ideas and concepts. It took me a few days to go over the material and do some research of my own, and see what sorts of things I might be able to contribute to. It’s certainly sparked my curiosity!
I was to prepare for a show and tell (an ideas brain-dump) for the next meeting. The examples I prepared included things from cut and paste transcriptions, 3D maps, FourSquare and social media, to story maps, to interactive audio presentations and oral history applications. I also gave a few indications as to possible uses of psychogeography with the themes. I hope to use this blog to share some of these ideas in later posts.
Initially I mentioned the difference between a “hacker” approach and the straight client and consultant way of doing development. For example encouraging collaborative play and exploration rather than hands off development. Allowing things to remain open. The further steps would be crystallizing some of these ideas – finding better examples and working out what we want to look at or devote more time to. We’d then be able to focus on some aims and requirements for a creative interesting project.
State of the Map Europe 2014 was in the German city of Karlsruhe. The city was a planned city – designed and built around 1715 – pre motor car, but with wide avenues, and half of the city seems to be a park. It’s also famous for being the home of the Karlsruhe Addressing Scheme – an example of a folksonomy tagging convention that everyone pointed to and adopted, due to the great mappers there – including the folks from Geofabrik.de who also organised the conference. Here are some notes from the conference:
Nature of the conference
The European conference seemed much more intimate with a focus on developer and contributors – compared to the US Conference which I think had more end users and people sent there by their bosses for their company. Pretty much every single session was on topic (except for the closing buzzword laden keynote!) – and as such there were no enlightening talks about psychogeography, general historical mapping, or other geospatial software. It was pure OSM.
Geocoder and Gazetteers
The only track in the conference – this was full of gazetteers with an announcement from OpenCage and MapZen – all appear to be using ElasticSearch – same as we (Topomancy) did last year for the NYPL and Library of Congress. Check out gazetteer here.
Trees – Jerry did a talk about mapping trees – about how they were represented in historical maps previously, and how we can use SVG symbols to display woods and trees in a better way. Jerry lead an expedition and workshop on the morning of the hack day to show participants the different habitats, surface types and variance in the environment that mappers could take into consideration.
Mapbox WebGL – Constantine, a European engineer of Mapbox did a fascinating talk about the complexities of the technical challenges with vector tiles and 3D maps. I really enjoyed the talk.
OpenGeoFiction - using the OSM stack to create fictional worlds – not fantasy or science fiction, but amazing experiments in amateur planning, utopian visions and creative map making. OpenGeoFiction.net
The fictional world of Opengeofiction is thought to be in modern times. So it doesn’t have orcs or elves, but rather power plants, motorways and housing projects. But also picturesque old towns, beautiful national parks and lonely beaches.
I love this project!
Vector Tiles – Andy Allan talked about his new vector tile software solution ThunderForest – being one of the only people to know the ins and outs of how Mapbox do the Mapnik / TileMill vector magic. ThunderForest powers the cycle map. Vector maps has lots of advantages and I think we’d probably use it for OpenHistoricalMap purposes at some stage. Contact Andy for your vector mapping and online cartographic needs!
POI Checker – from the same house as WheelMap.org comes POI Checker – it allows organisations to compare their data with data in OSM – and gives a very neat diff view of Points of Interests. This could be a good project to follow.
OpenHistoricalMap There were a few things about historical maps in the conference, although in my opinion less than at any other SOTM previously. I did a lightning talk about OpenHistoricalMap and completely failed to mention the cool custom UK centric version of the NYPL’s Building Inspector.
Opening Keynote – this was peppered with the history of the city and gave a number of beautiful historical map examples. Watch the video.
Map Roulette v2 – Serge gave a talk about the new version of Map Roulette – it is being customised to be able to run almost any custom task on the system. We chatted a the hack day to see if the tasks from the Building Inspector could be a good fit into the new Map Roulette – I will look into this!
NYPL Warper – New Maps!
This weeks news was about a project I’ve been working on for the last few months with Topomancy – adding a whole load of new maps to one of the largest libraries around the New York Public Library. These were added to an award winning crowdsourced geo-rectification, historical map exploration and discovery application. Users can download full resolution TIFF files without the need to login, and if the map has been geo-referenced/rectified/warped, then you can freely download the warped versions too. The images are all in CC-Zero licenses – so, effectively Public Domain in nature. Credit to the library is appreciated though.
Folks may recognise that the Warper has been around for a little while now, and so here’s what we did: We hooked it up with the NYPL Digitial Collections API – this changed the way it requested , instead of internally requesting images from the Image Server, it uses the API properly. A whole suite of import processes were also generated to enable to search of maps from the repository, importing individual maps sheets, the import of individual atlases or layers full of maps, and most usefully the import of newly digitized maps. A by product of this was to extract some of the library code into the nypl_repo Ruby Gem. There’s even some documentation for the nypl_repo gem for interacting with the NYPL Digital Collections API.
A few days ago saw the most recent meeting of the Superposition group in Leeds. That nights was under the theme “Magic Illusion and Perception” I’ve pinched a lot of the text in this post from that one!
There were four talks. The first was about the “curiosity” machine that uses lasers to draw moving images on clouds, the zoopraxiscope, and it was taken up in a small plane where images of a moving horse were projected onto a cloud. Wonderful stuff.
Ben Dalton’s talk ‘Zines in the age of ‘big data’?’ introduced and proposed the idea of bundle publishing. At odds with current trends in digital distribution, bundle publishing involves editing a large collection of digital content and then publishing it on a specific date as a single, large ﬁle. This was the most intriguing talk of the evening, where instead of streams, or blogs, or things, that media could be published and shared in huge bundles of files. I’m encouraged partly by online publications such as The New Inquiry as an alternative to a blog roll. Ben is also interested in pseudonyms. A team of writers may publish using the same pseudonym – the pseudonym would have its own character, style of writing. There was also the pseudonyms as used by “anon” users – names that become used and familiar to people.
Experimental jazz musician and neuroscientist Christophe de Bézenac talked about the blurring of self and other in music and psychosis. Having studied at Conservatoire de Strasbourg, and been a regular performer at international music festivals he explained how perceptual ideas have guided his musical practice and how his musical work has, in turn, fed into his empirical/neuroscience research into psychosis. This talk really excited the audience, with discussions about what is ambiguity. Ambiguous language, music etc. What is the crowd? What is the mob? Can someone experience things as a group? Fascinating stuff.
Professional Magician and Slight-of-Hand artist, Tony O’Neill discussed his creative process within the magical syllabus and sharing his current findings on the power of suggestion and self belief. It showed that magic, fortune telling could be used to help people, even when they knew what the process was all about. I wonder if a city needs more magicians, or if this type of magic could be used on a group of people. Things discussed include things like you can change someone’s mind by planting suggestions, etc.
Part of a series of posts to cover some small projects that I did whilst not being able to work. They cover things from the role of familiar strangers on the internet and anti-social networks, through to meteorological hacks, funny memes to twitter bots. This post is about a funny meme image generation service.
Sometimes I surf the internet for funny pictures. Although the ones with cats I have a healthy distrust for – there was one class of amusing image which caught my eye. Those funny or inspirational London Underground passenger informations signs. I was seeing these every week and thought… “I could do that”. So I did, created tubesign.herokuapp.com and a few other people found it funny. At one point there was about 50 people visiting at any one time and when I put the statistics on there was 13,000 views on the second day with an image being created one every second. At time of writing it has had over 50,000 views.
How I did it.
First of all I looked into fonts – I wanted to get a good handwriting font which would look as if someone had used a marker on a white board. Google fonts delivered, and I chose Reenie Beany.
It uses Sinatra, Ruby and Rmagick and is hosted on the Heroku platform – even at it’s busiest it was able to cope on the free tier. It doesnt use any database. It caches requests for images though.
I use a bit of random number generation to change the angle the text is written at, and change the indent a bit.
Viral & coverage
I posted this on facebook and my friends gave it a go, with some hilarious images being created, and then it spread to twitter, where more and more people found it. Then blogs, mainly London based blogs found it.
Someone said that the original image was someone’s copyright, so I changed it to a CC-By-SA image by Flickr user Lrosa, which also meant that all images created were under the same licence.
There was about 50 people visiting at any one time and when I put the statistics on there was 13,000 views on the second day with an image being created one every second. At time of writing it has had over 50,000 views. Now the traffic is in the hundreds, with number of people visiting right now enough to be counted on one hand.
- Live preview
- Better font rendering – defocus
- Add range of images for different places (Bombay signs, Leeds Metro signs etc)
- Store images, allow voting, create gallery
Part of a series of posts to cover some small projects that I did whilst not being able to work. They cover things from the role of familiar strangers on the internet and anti-social networks, through to meteorological hacks, funny memes to twitter bots. This post is about a meteorological hack.
DataPoint is a way of accessing freely available Met Office data feeds in a format that is suitable for application developers. It is aimed at professionals, the scientific community and student or amateur developers, in fact anyone looking to re-use Met Office data within their own innovative applications.
The year before this, in Denver, USA, I was shown by a couple of awesome mapping and weather geeks a mobile app that showed when it was going to rain, and more importantly when it wasn’t going to rain in very high temporal resolution. You can use the app and know whether to get a swift half and then leave to get the bus, or whether to stay in for an hour until the showers end. It was very detailed and highly useful. This app Dark Sky App
was freaking awesome. And I want here in the UK, so when the Met Office announced their API I was interested.
You cannot do what DarkSkyApp does with the Met Office DataPoint API though – what you can do is do some interpolations though. The API for precipitation forecasts only gives access to a 3 hourly map tile.
Although further poking around shows that they do have an undocumented 1 hourly image.
These map tiles then could be used. http://rain-graph.herokuapp.com is the resulting application with the code here: https://github.com/timwaters/rain_graph
It’s a Ruby Sinatra application which for a location, grabs the precipitation tile for a defined location for each hour from now. It looks at the pixel value for the given location and determines the amount predicted. It shows when the heaviest rain is predicted and when it would stop. Interpolation is given by the graph engine itself – no fancy meteorological modelling is done (at this stage). It uses Chunky_png to get the pixel values.
All requests are cached to avoid hitting the MetOffice API and because an image won’t change for an hour. Additionally it uses another API method to get a human readable upcoming forecast text for that location, and displays it under the graph. Contrary to popular global belief it’s not always raining in the UK, and so most of the time you will never see a a graph showing something!
Pixels to Lat Lon:
Since a lat/lon location is quite specific, it could map to one pixel in a tile, and that pixel could have a lower or higher value than the ones surrounding it. I could use a kernel average – do a 6×6 pass over the pixel and get the average value. But since there are tiles are lower zoom levels, by zooming out, the spatial extent of the pixel would equal that larger area – it would do the work for us.
Interpolation between forecasts:
It wasn’t clear if the forecast images showed the predicted situation over the whole hour, or whether it showed the situation at that moment. Should a user look at an animation to see how rain cloud moves across from A->B and guess that in between that there would be rain, or should they think that that there would be no rain if there is no rain shown?
It looks a bit bland – we should show the image tiles underneath – perhaps shown when hovering over a point.
I haven’t tested the accuracy of this.
Location hard coding:
The text forecasts are hardcoded to a set number of regions, but we could do a closest point and get the correct forecast for the given lat and lon.
Use Yr.No API
Yr.no has detailed hour by hour forecasts API for a place giving the amount of precipitation.
