MTSatellite is "realtime" web mapping system for [Minetest](http://minetest.net) worlds.
|
|
|
|
|
With this system you can play your world and you instantly have an online map of it which
|
|
|
|
|
can be share on the web.
|
|
|
|
|
|
|
|
|
|
To get a glimpse what it does watch [Realtime Webmapping for Minetest worlds](http://youtu.be/iYEROGPj7RI)
|
|
|
|
|
on YouTube.

|
|
|
To use it you have to configure your Minetest server to use the Redis backend data store.
|
|
|
|
|
Instead of a real Redis server you have to run **mtredisalize**. This server stores the data
|
|
|
|
|
in an optimized form and collects changes made to the world over a configurable amount
|
|
|
|
|
of time periodically. After a cycle of collection the web server **mtwebmapper** is triggered
|
|
|
|
|
to regenerate the map. To not fully regenerate the whole world map but only the differences
|
|
|
|
|
the map has to be pre-rendered with **mtseeder**.
|
|
|
|
|
|
|
|
|
|
* [mtredisalize](cmd/mtredisalize) is a server which has to be configured a Redis backend to the
|
|
|
|
|
Minetest server. It stores the data in an opitimized form to make updates of the pre-rendered map fast.
|
|
|
|
|
It is also used to track the changes made to the world. They are aggregated over
|
|
|
|
|
a defined time interval and then send to the mtwebmapper server.
|
|
|
|
|
|
|
|
|
|
* [mtwebmapper](cmd/mtwebmapper) Web server that serves [Leaflet](http://leafletjs.com) compatible tiles to a
|
|
|
|
|
web browser. Running in the background this server updates the pre-computed map tiles.
|
|
|
|
|
|
|
|
|
|
* [mtdbconverter](cmd/mtdbconverter) is converter between Minetest databases. mtredisalize works
|
|
|
|
|
best if you use a special interleaved LevelDB key schema. To bring your old database (LevelBD or SQLite3)
|
|
|
|
|
into this format this tool does the job. It can also be used to convert the interleaved database
|
|
|
|
|
back to a plain LevelDB or SQLite3 one.
|
|
|
|
|
|
|
|
|
|
* [mtseeder](cmd/mtseeder) pre-computes all tiles of the map of the world plus a set of pyramidal overview images.
|
|
|
|
|
Even playing in a dynamic and fully changeable world most of the data is pretty constant over time. Therefore
|
|
|
|
|
it make sense to do only small updates on pre-calculated images instead of generating
|
|
|
|
|
the map entirely on the fly.
