To find every map feature

Is it true that one can see every possible map feature, if he travels the entire area generated at start?

The co-ordinate starts at 0, goes to 0’179, then to 1’0, then to 1’179, so a 179x179 map seems a default unit, and is exactly what one sees when he reveals map. This is small though, and does not have every features.

How large is the area generated when the player character spawns? How many 179x179 blocks does it contain?
