Explorer Map

Explorer maps are special maps used to aid in finding rare generated structures.

Obtaining
Explorer maps can be bought from cartographer villagers by unlocking their tier 4 trades. An ocean explorer map is sold for 12–20 emeralds and a compass, and a woodland explorer map is sold for 16–28 emeralds and a compass.

Locating structures
There are two types of explorer maps: woodland and ocean. The maps differ from a normal map, in that it shows the area's land-water outline, as well as an orange striated texture for areas below sea level, and the blank map texture for land above sea level. The maps show a section of land that contains a woodland mansion or ocean monument respectively. This may not be the nearest such structure to the player. The structures are displayed as a small icon. If the player icon is smaller than it would be on a normal map, that means the player is a great distance away. When the player is less than 1027 blocks away from the map border, the icon will return to the proper size. When the player reaches the map's area of land (512*512), the map will fill in like a normal map.

Cloning
The parts of the world that have already been explored and mapped will be copied, and newly explored areas will appear on both instances. In Creative mode, cloned explorer maps can be obtained by pick blocking on the explorer map displayed on item frames (make sure the map is out of your inventory when using pick block, or else that map will just be moved into your active hotbar slot).

ID
Explorer maps use the item id of regular maps,.

Item data
An explorer map differs from a map in that its  tag is set, which includes a   and a  ; also its   list includes an entry for its target monument or mansion. Its map item entry is identical to that of a normal map, except that by the time the player sees it, its  byte array is pre-filled with explorer maps' characteristic land-water boundary lines and water shading.


 * Item data
 * : How the map looks in an item slot. See also Player.dat_format.
 * : The localization string to translate; in this case, either  or
 * : Color codes are calculated from the Red, Green and Blue components using this formula:  Red <<16 + Green <<8 + Blue .  Monument maps use 3830373, which is . Mansion maps use 5393476, which is.
 * : One of these for each icon on the map. Explorer maps always have at least one representing their target.
 * : For explorer map target structures, this is "+".
 * : Rotation of the icon. For explorer map target structures, always 180.
 * : 0-based index of the sprite used in /assets/minecraft/textures/map/map_icons.png: 9 for a monument map, 8 for a mansion map.
 * : x-coordinate of the target structure icon on the map
 * : z-coordinate of the target structure icon on the map
 * : x-coordinate of the target structure icon on the map
 * : z-coordinate of the target structure icon on the map

Trivia

 * When a cartographer generates the trade offers for the explorer maps, it chooses the location of one of the nearest structures of the respective type (ocean monument or woodland mansion) in a chunk that has not yet been generated. This means that it will always select a structure that no player has visited yet. This is especially useful in SMP for finding unraided ocean monuments in order to obtain sponge blocks.
 * For the reason above, explorer maps obtained from one cartographer will always be the same. Also, if two cartographers unlock the explorer map trades approximately at the same place and the same time, the map locations will usually be identical.
