TTG Composer
Spatial Assets for Transit System Visualization and Development
Build transit-facing visuals from explicit street structure instead of guessing from text alone. Transitguy Composer uses street-structure modes to capture the street condition first, then drives the render layer from that image state.
Transitguy Composer is an access-managed Treasury surface. Streetmix source code and adapted visual assets remain attributed under AGPL-3.0-or-later where applicable.
