This project uses bitmaps as references to place landcover on a Unity terrain.The XY coordinates of the bitmap are correlated to the XZ coordinates of the Unity terrain. Each pixel's color acts as a key representing the placement of textures, trees, and meshes. The pixels are evaluated with various modifiers to determine the placement of each asset.

The example below highlights the fernan lake watershed and each pixel color represents a fuel type from the Scott and Burgan Fire Behavior Fuel Model containing 40 different models. We demonstrate this FBFM system because of the models available at the landfire.gov website, FBFM40 was the best balance of fuel model detail and model depth, and because the FBFM provides an abstract structure to benchmark the PLD's features and performance.
