Tutorials/Programs and editors

The Minecraft community has created dozens of programs that can be used to enhance the game. Server software is so numerous that it has a page of its own. The most popular programs are Mappers that create an overhead view of a level. Map Editors let you directly alter a level outside of the game. Level Generators create new terrain types and block patterns that aren't available normally. Mods and Total Conversions add completely new features or modes of play to the core Minecraft game. Backup Utilities make it easy to play your favorite worlds on mulitple computers as well as giving you peace of mind knowing that your worlds are safe. Finally, there are Specialized Programs for editing your inventory, simulating Redstone circuits, and altering game files at a low level.

Software is Windows-only if not specified.

Mappers
Overhead mappers create a literal map of your level'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.

Minecraft Overviewer
A Google Maps powered overview that draws your map in 30 degree isometric mode with a high level of detail. Source code and demos are available on github.

OpenCraft Plotter
From the OpenCraft project, comes Plotter. It is a Java library and standalone tool designed to have an expansive suite of visualizations for every known format of Minecraft save file.

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

Map Editors
Map editors alter a 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.
