1. A method of testing an incrementally updated map database, the method comprising:

  • receiving a list of objects derived from an update for the map database;

    populating a table with map tiles associated with the objects, wherein the table includes a first map tile and a second map tile that is adjacent to the first map tile;

    generating a test script including a consistency check algorithm for the first map tile associated with one or more of the objects of the update and the second map tile associated with one or more of the objects of the update, wherein the consistency check algorithm is configured to determine whether references of the second map tile to all objects associated with the first map tile are valid and whether references of the first map tile to all objects associated with the second map tile are valid;

    storing the test script in a memory;

    executing the test script on the navigation database to generate a return value, wherein the memory stores a threshold value; and

    finalizing the update package to the navigation database when the return value indicates errors less than the threshold value and roll back the update package when the return value indicates errors in excess of the threshold value.
