Computer Cartographer
This Minecraft mod adds a peripheral to ComputerCraft Tweaked that allows for interfacing with common mapping plugins (BlueMap, Dynmap, Pl3xMap, and Squaremap).
Information
Using the peripheral, you can dynamically draw POI (including custom icons), lines, circles, rectangles, and arbitrary polygon area markers to the mapping plugin of your choice.
You can create pathing previews using line markers, add real-time GPS pins for turtles on the move, or (if you have a mod with an entity sensor peripheral) put all the mobs in your area on the map.
See the wiki for usage details.
Here we've drawn the location of two turtles onto the map along with the route one of the turtles is currently taking. Additional information, including the status, progress, and remaining fuel is displayed in the details of the pin.
Using Plethora's entity sensor, you can add all the mobs in your area to the map!
