The "where is this map" feature is not available in some cases where it would be extremely useful
For example, if you go "map database" -> then "prontera field", then each map has a "where is this" link.
On the other hand, say I go "map database" -> "prt_fild03" (by using the second combo box). Then I get a detailed view, but without the "where is this map" link.
If you start with monster search, then click on one of the maps next to the monster, you get the latter kind of view without the "where is this map", which is the scenario I most frequently encounter in practice.
You can find a map by hovering over the "world map" and searching manually, but the maps are not really in numeric order, so it's not very convenient.
