This cartogram shows the land surface transformed according to the absolute travel time that is necessary to reach the nearest large city using a gridded cartogram projection. The larger a grid cell appears, the more remote it is, highlighting the least accessible spaces on the planet (Antarctica has not been included in the transformation and appears in its original shape).
