Back in Java days we had very detailed maps with changes and stuff. red51 somewhere said its not that easy in unity as in java and will take time. So meanwhile i've done something here and there and i have created an online map for my servers. In theory every server could have one but currently there is a nodejs bridge needed (that not every admin can (or wants to) install) running in parallel to the game server that can read the surface scanned from admin utils plugin and serve it, so the rendering service i'Ve created can then create a map from the data. When the API gets more webserver capabilities with the next version the bridge service gets obsolete and every server could expose surface data that will then be consumed by a rendering service.....
Long story short, i tought it would be cool to bring back the rendered online map into the game, so everybody (with a map item) can use the "explorers map" showing explored areas.
I'm not sure if there would be any interest besides myself so i have started planning but not yet done anything. Maybe at some time in the future this plugin will get obsolete when the ingame map gets something similar.
Here a picture from the old Java map which was exported by my "Rising Maps" plugin in Java
And a compared view from the surface data i have extracted from unity
