BlueMap is a tool that generates 3d-maps of your Minecraft worlds and displays them in your browser. Take a look at this demo. It is really easy to set up - almost plug-and-play - if you use the integrated web-server (optional).
The Sponge/Spigot-Plugin automatically updates your map as soon as something changes in your world, as well as rendering newly generated terrain and managing the render-tasks.
Some features and some blocks are still missing. Especially some tile-entities will not render correctly/at all. See below for a list of what is planned for future releases.

There is the latest recommended release, or if you want to try the latest (but not much tested) features you can choose the latest snapshot from here!
Getting started
BlueMap is mostly plug-and-play. Just install it like every other Paper-Plugin and start your server. BlueMap will then generate some config-files for you in the ./plugins/BlueMap/ folder. Here you can configure your maps and the web-server.
Please read the wiki for more information!

Metrics and Webserver
BlueMap uses bStats and an own metrics-system and is hosting a web-server!
Metrics are really useful to keep track of how the plugin is used and helps me stay motivated! Please turn them on 
bStats: All data collected by bStats can be viewed here: https://bstats.org/plugin/bukkit/BlueMap.
It can always be turned of in bStats’s config.
own metrics: Additionally to bStats, BlueMap is sending a super small report, containing only the implementation-name and the version of the BlueMap-plugin to my server. I do this, because there are some other implementations for BlueMap (Fabric, Forge, CLI) that are not supported by bStats. Here is an example report:
{
"implementation": "spigot",
"version": "0.0.0"
}
This data-collection can be turned off in BlueMap’s core.conf configuration!
web-server: The web-server is enabled by default but can be disabled in the plugin-config. By default the web-server is bound to all network-interfaces (‘0.0.0.0’) on port 8100 and is hosting the content of the ./bluemap/web/-folder.

Todo / planned features
Here is a todo-list ordered by what i right now think is the priority, but might always change or be reordered at my discretion. (I develop BlueMap in my free-time, so nothing here is a promise and there are no ETA’s)
