Mappers
Overhead mappers create a visual map of your world's terrain. Many mappers have options for different overhead and angled modes, and some will limit the map to selected block types or slice the map into smaller pieces.

Map Viewers
Map viewers are read-only and have an interactive interface.

Map Editors
Map editors alter an existing level's terrain or other properties, such as player position and time of day. Some of them also let you edit your inventory and generate terrain.

Map Generators
These programs will either create a new level with custom terrain, or "implant" new blocks into an existing level.
