It is much better to have a written map than having someone else teach you the thing orally.
you know the telephone game ? the first person say something to the second person and that person repeat what the first person said to the 3d person etc ... and at the end ( no matter how many people there is ) the message is completly different.
with written map everyone will have the same info and future generation will have the right info.
