These maps show the density of submarine communications cables around the world. The top map displays unweighted line density, while the bottom has been weighted by bandwidth (e.g., Gbps).

The data come from Greg Mahlknecht’s website (see link below). He states that the accuracy of the layout varies, as he was able to obtain exact routes for some cables, but other routes are schematic depictions based on landings. In addition, he generally excludes cables below 1 Gbps. It should also be noted that some of these cables are defunct, or are not yet activated. So these maps should be considered generalizations of global submarine communications; they are not exact, but provide an overall sense of the layout.

Historical Map: Austrian Edition of Airey’s Railway Map of London, 1876

Simply beautiful rail line and junction map from the earliest days of what would become the London Underground. Extremely notable for its use of colour-coding to differentiate between the lines of all the different operating companies. In the days of chromolithographic printing, using this many different colours would have been an expensive, highly technical and time-consuming task.

The following text is taken from the raremaps.com description of this map:

Extremely rare early Austrian edition of John Airey’s famous Railway Junction Diagram of London (not in the British Library!).

The present map is an early Austrian edition of Airey’s most important single map, Airey’s Railway Map of London and its Suburbs, illustrating the innumerable railway lines leading out of London, and importantly depicting the earliest two lines of the new London Underground System, along with at least one proposed line which was never constructed. Airey published his first edition of the map under that title in 1875, which subsequently ran into several editions. It, in turn, was based on a map that appeared in Airey’s book, Railway Map Diagrams (London, 1867).

The map’s fascinating an innovative visual composition was originally conceived as part of a series of diagrams illustrating the rapidly expanding routes of the various railways throughout Britain. With its carefully placed and labeled colored lines, it is the true precursor to Henry Beck’s celebrated London Underground Map of 1933. In this sense, Airey’s maps were the first truly modern rail transport maps, and they set the gold standard for such publications throughout Europe and America.

London was the first major city to be served by railways (a technology invented in 1830), with the first line connecting London Bridge and Greenwich being completed in 1836. During the ‘Railway Boom’ of the 1840s, eight new lines were added connecting London with the countryside in virtually every direction.  Since that time, two new major lines had been added and new spurs had been built to access different parts of the city. Airey was commissioned to produce his diagrams by the Railway Clearing House (RHC), founded in 1842, it acted as an umbrella organization to collect and manage revenue from the various independent railway lines.

Perhaps the most important aspects of the map are the inclusion of the World’s first two Underground (or Subway Lines), the Metropolitan Line and the Metropolitan District Line (the original components of today’s District and Circle Lines). The Metropolitan Line was first opened in January 1863, while the District Metropolitan was completed in December 1868. Airey’s diagram shows how the new medium of the Underground integrated with the established railways. 

The map also records the proposed location for one of the early underground lines which was never constructed, the London Central Railway. The London Central Railway was formed in late 1871 for an unsuccessful north-south promotion sponsored by the Midland Railway and the South Eastern Railway, for a link between St Pancras and Charing Cross Stations. The name again surfaced In 1884, when a London Central Railway Company sought unsuccessfully for authority to build an electrically operated line from Trafalgar Square to St Martins-le-Grand via Oxford Circus and Oxford Street. This was intended to be an extension of the Charing Cross & Waterloo Electric Railway (now part of the Bakerloo line). This was authorized in 1882 but never built. 

The present, apparently unrecorded, edition of the map, may have been first published in 1876 in Vienna by the publishing firm of R. v. Waldheim, a leading house specializing in newspapers, music books and lithographic prints. From the inscription in the upper-right corner, it seems that the present map was originally issued within a book. While it is not clear which publication it is, it is possible that the map was associated with a later edition of the rare work Die Concurrenz im Eisenbahnwesen, a railway book first published by Waldheim in 1873. In any event, it is a fascinating testament to the contemporary pan-European fascination with Airey’s groundbreaking cartography.

Our rating: Simply beautiful: detailed in scope, but amazingly clear and simple in execution. Five stars.

5 Stars!

Unlike like Emperor Kuzco, I was actually born with an innate sense of direction.  If you’re like me, and you use the Sun to navigate, you probably appreciate cities with gridded street plans that are oriented in the cardinal directions. If you know that your destination is due west, even if you hit a dead end or two, you’ll be able to get there. However, not all urban planners settled on such a simple layout for road networks. For some developers, topography or water may have gotten in the way. Others may not have appreciated the efficiency of the grid. This visualization assesses those road networks by comparing the relative degree to which they are gridded.

To generate the graphic, I first calculated the azimuth of every road in ten counties (plus one parish and D.C.). I tried to choose consolidated city-counties to keep the focus on urban centers, but for larger counties, I opted not to clip the shapefile to the city boundary. All calculations were made in a sinusoidal map projection using the central longitude of the area of interest. I then graphed the angles on rose diagrams (wind roses) using bins of 5° to show relative distributions for each area. The plots were scaled such that the maximum bar height was the same on each rose. To ensure rotational symmetry in the plots, each azimuth was counted twice: once using the original value and once using the opposite direction (e.g., 35° and 215°). As such, all streets, regardless of one-way or two-way traffic, were considered to be pointing in both directions.

The plots reveal some stark trends. Most of the counties considered do conform to a grid pattern. This is particularly pronounced with Chicago, even though much of Cook County is suburban. Denver, Jacksonville, Houston, and Washington, D.C., also have dominant grid patterns that are oriented in the cardinal directions. While Philadelphia and New York are primarily gridded, their orientations are slightly skewed from the traditional N-E-S-W bearings. Manhattan is particularly interesting because it has a notable imbalance between the number of streets running the width of the land (WNW to ESE) and the length of the land (NNE to SSW). New Orleans and San Francisco express some grid-like forms, but have a nontrivial proportion of roads that are rotated in other directions. Downtown Boston has some gridded streets, but the suburban grids are differently aligned, dampening the expression of a single grid on the rose diagram. Finally, the minimal geographic extents of the grids in Charlotte and Honolulu are completely overwhelmed by the winding roads of the suburbs, resulting in plots that show only slight favoritism for certain street orientations.
