1. A system for automatically annotating a second map when a first map is annotated, the second map being geographically substantially similar to the first map, the system comprising:

  • a map display;

    a map processing platform in communication with the map display, whenever said map processing platform is adapted to;

    receive a user annotation at a first location on the first map expressed by first map coordinates;

    convert from the first map coordinates to corresponding geographic coordinates using a georeferencing function of the first map;

    convert from the geographic coordinates to corresponding second map coordinates using a georeferencing function of the second map; and

    display the user annotation on the second map at the second map coordinates;

    a storage platform coupled to the map processing platform; and

    a user interaction device coupled to the map processing platform.
