London Population Change 2001 to 2009

In a previous post I talked about the Index of Multiple Deprivation (IMD) in London, and how a “standard” representation only reflects the geographical reality of the land. By utilising a cartogram tool this potential issue can be overcome by rescaling each areal unit by its resident population, for the IMD I used mid-year population estimates available from the Office for National Statistics at Lower Layer Super Output Area (LSOA) level. To add a layer of context to the previous maps, I have constructed cartograms for London to illustrate the change in population between 2001 and 2009. I have used 2001 census data along with 2009 mid-year population estimates to calculate the percentage change for each of the 24,140 output areas (that contain on average 250 individuals nationally) that make up Greater London for the age ranges: 0-4, 5-14, 15-24, 25-44, 45-64 and 65 and over. To create the cartogram aspect of the maps I have used the total population of that particular age range in 2009 to rescale each areal unit. I have also produced the same population change maps using the “standard” representation of London to allow comparison with the cartograms. The results of this can be seen […]

Force Directed Graphs for Visualisation of Search Results

I’ve been looking at the D3.js library for data visualisation in Javascript. This is the new evolution of Protovis from the Stanford Visualization group, and uses SVG to create dynamic visualisations from raw data. What interests me is how large archives of geospatial datasets can be searched for relevant information. On MapTube at the moment … Read more

Cruise Liners and the Sinking of a Dream

The dramatic events involving a sinking cruise ship in the Mediterranean Sea has all of a sudden brought the topic of large cruise ships back to the front pages of News Channels from around the world. Recently only the size could possibly get the ships into the news, but a disaster is always a good selling point.

The story that unfolded over the past days however, is more than only a sunken ship, but a real crazy entangling of very unfortunate events and, as it currently seems, poor judgement of the captain. The ship passed the coast of Giglio way too close and was not at all even meant to be there, but manually steered into the disaster.

It seems almost unbelievable that a nearly 300 meter luxury cruise liner can sink just like that. Even more so as it effectively happens only 100 meter from shore. On any News coverage, alway there is the save land not just on the horizon, but right next to the ship. It is only a 100 meter or so to shore. Even so the tragic events have claimed several lives with about 19 people still being missing at the time of writing.

Large cruise ships don’t just sink they go down with a dramatic story and this is another one of these events that bring about the mistic and special atmosphere surrounding the large passenger ships sailing the seas of the world. There are numerous stories and practices entangled in this picture of such large vessels, including the glamour and wealth on board all the way to the understood but not written down practice of ‘women and children first’ and the captain leaving the shop last. Examined in detail by the BBC.

Definitely the most famous Ocean Liner disaster is the Titanic disaster where the branded as unsinkable ship sinks after a collision with an iceberg in the North Atlantic Ocean during its maiden travel from England to America in 1912. Between then and now there are a few accidents recorded involving large cruise ships, but the industry was able to build up a very clean and save image for travels on large ocean liners.

Size matters, especially in this business. Steadily the companies are building larger units, with Oasis of the Seas currently being e largest ship being in operation. It offers space for 6296 passengers and 2165 crew. Under construction are at the moment Project Sunshine 1 and 2 expected to have a total capacity of 5700. It is size and luxury in the form of entertainment and facilities offered as selling points to attract the passengers.

Modern liners offer a lot more than only the swimming pool and the tennis court. There are water slides, wave board pools, ice rinks, rock climbing, basketball court and so on. Guest can browse through boutiques and shops, visit several restaurants and bars, entertainments show or casinos and cinemas. There is around the clock entertainment from yoga classes to guided running sessions and wine tasting on offer. Plus of course the captains dinner is still the climax of every cruise.

Cruise liner are in heir nature self contained and built to carry all necessary support systems beside the entertainment facilities. In fact these large ocean liners are more like small cities in themselves capable of catering for as many as 8000 people over periods of more than a week, with many systems being able to run for at lest a week without calling at a port.

The key difference between the types of ships is between cruise ships an ocean liners. As the name indicates the two categories serve very different purpose. The liner is built for a linear connection ferrying passengers between ports traditionally between the old and new world from Plymouth to New York. Cruisers on the other hand traditionally have circular routs manly for pleasure travels returning to the port of departure. There are also technical differences setting the two categories apart. Liners are built for rougher seas running deeper making smaller ports inaccessible. Cruisers are built with more passenger space, focused entertainment and specially designed for higher numbers of outside cabines and fewer inside cabins.

By now however, the only dedicated ocean liner really is the prestigious Queen Marry 2. Since 2010 is she the last remaining ocean liner representative running between Southamton and New York. However even QM2 is equipped with specialised entertainment, and runs on cruise tours every now and then.

Cruise liners carry a special aura with them and were especially popular in the first half of the 20 century with especially the modernist movement. Famously the architect Le Corbusier stylised the ocean liner to become the ultimate triumph of technology and symbolised the ideal city as a self contained organism. Especially in his book Toward an Architecture (). It’s also the aspect of mobility / traveling that implies the freedom connected to the cruise tours. An perception of independence and sovereignty is what attracted and still continues to do so.

There are a number of famous floating city project dreamed of by architects since the modernist movement. The Triton City by Buckminster Fuller or the freedomship project. But of course cruise ships have also entered the virtual world and SS Galaxy is one of the really bog projects in Second Live with a handfull of people full-time playing the crew on a virtual deck.c

Technology is still today a major aspect of cruise line travels from the ship design, the build, the infrastructure and the built in technology. Machines are very powerful but at the same time capable of very fine manoeuvring amid, buy the size of the latest ships dwarf ports. Navigation is built on the latest technology covered by several backup and parallel systems. Even though the atmosphere is relaxed and definitely majestic, the equipment is built on very high safety standards, covering a whole range of applications and devices. The bridge of a cruise liner is a high technology command centre covering the complexity of the entire ship.

Besides all these aspects however, the spirit of innovation and conquering of nature using technological power has faded. For cruise ships are marketed not any longer to experience the power and genius of man, but to celebrate one self. Where in the days of the ocean liner passengers would be amazed by the sheer idea of traveling on such a ship across the Atlantic, admiring its power, today guests are demanding services and entertainment.

The floating city has become an fantasy entertainment park and is no longer pushing the boundaries of innovation nor is it representing progress. It has become the opposite and pretty surely the modernists would no longer see the floating amusement parks with “balcony-laden floating condominiums”, as they are described in a Wikipedia article as a representation of their fascination.

Geospatial Science Seminar 10.01.2012

Spatio-temporal linkage of real and virtual identity. Dr Muhammad Adnan, UCL Department of Geography. Professor Paul Longley, UCL Department of Geography. To download a PDF of the seminar please click here. Abstract. A name often provides an indication of its bearer’s cultural, ethnic and religious affinity in the real world (Mateos et al 2011), as well as the place in which he or she probably lives (Cheshire and Longley 2012). This presentation begins to consider whether and how tokens of virtual identity can be linked to the probable characteristics of people and places. We begin with a retrospective on two strands of work at UCL that has used computationally intensive analysis to classify populations into: (a) ‘naming networks’ based upon social similarities in naming conventions; and (b) ‘surname regions’, based upon locational proximity of people who share names with common geographic roots. Together, these two approaches offer the prospect of context-sensitive generalisation of the geography of naming conventions, as well as measurement of the long term effects of population change. The second part of the presentation begins to consider the linkage between georeferenced email addresses and the probable names of their owners. We begin a preliminary investigation of data harvested […]

The Power of Comparison: Just How Big Is It?

  If I said a country was 1594719800 metres squared it would mean a lot less to you than if I said it was about the size of Greater London (so long as you know about how big Greater London is). For this reason the media tend to report the extent of a flood in …

Moody Snow Timelapse

A few days in the Swiss Alps around Saas Fee and on is completely drawn into a world of rough mountains and beautiful snow scenes. Its this time of the year again, its freezing cold and condensation collects at the windows through the night. Your breath is visible as you step outside, the air is thin and views are clear. Winter is finally here.

Video by Patryk Kizny showing amazing views of boiling clouds from the highest mountain peaks, landscapes of the glacier of SaasFee and other locations develop into much more abstract audio-visual form along with the weather changes. The film is also a tribute to free of light pollution places featuring fantastic views of the MilkyWay.

The short timelapse film “Altissimo” has been shot entirely in motion-controlled timelapse technique. The team shot over 45 000 single frames (over 700 GB of RAW data) using a few cameras in various locations of Switzerland during a one-week stay in Switzerland in May, 20111.

Coming of Age: R and Spatial Data Visualisation

I have been using R (a free statistics and graphics software package) now for the past four years or so and I have seen it become an increasingly powerful method of both analysing and visualising spatial data. Crucially, more and more people are writing accessible tutorials (see here) for beginners and intermediate users and the development …
