Large towns should have a series of bus maps in addition to the network map, each showing all the services within one zone of the city and outside that zone only those routes extending from that zone to other areas—like the tentacles of an octopus extending out from its body. These "octopus" bus maps, or "octobus" maps, are not merely fragments of network maps; hence, they have rarely been produced by hand. Using a computer to produce them can solve the problem of the uneven concentration of detail by programming it to distort the map. The computer can also be used to determine the routes to appear in each map and to define appropriate zones. The whole central zone should be enlarged by the same amount—i.e., without distortion—but the tentacles should decrease in scale as one moves outwards. As the power used in the distortion formula decreases, the central disk takes up an increasing proportion of the available space, while the peripheral areas are shown at decreasing scale and with increasing distortion of shape. If the scale needs to be enlarged around a secondary centre, the distorted position of each point can be determined from the vector sum of the displacements calculated from formulae based on the primary and secondary centres
