Massive World Generation Tool:

 

 - Capable of generating infinitely sized worlds in extremely small amounts of time.  Complete with terraforming, erosion and world objects (trees/shrubs/buildings), all automated.

 

 - World created using fault line and plate collision algorithms

Simulate over hundreds of thousands of years of plate movement and collisions to create mountain ranges, hills, islands, and plains.

 

 - Terrain created by using USGS geological height data

 

 - Objects placed using generation algorithms based on temperature, altitude, and rainfall values of the world.

 

 - Specific USGS data is then rotated, scaled, eroded, then placed in the world based on the data collected from the plate collisions
