DIRSIG Plume/Sensor Integration (QUIC and PIMS)

Research Team: Niek Sanders, Scott Brown

Task Scope: Los Alamos National Laboratory (LANL) has developed QUIC, a powerful tool for simulating wind fields and gas plumes in urban environments. This task is focused on integrating LANL's QUIC model with the DIRSIG radiometric propagation model. The final product will allow users to easily generate DIRSIG hyperspectral imagery containing QUIC plumes.

There are several distinct features needed for tight integration. First, a tool must automatically convert the geometry (buildings and trees) of a DIRSIG scene into their QUIC equivalent. The QUIC model must then be applied to the converted geometry to compute the wind field and plume dispersion. Finally, the resulting plume must be rendered in DIRSIG.

Task Status: Preliminary integration work has been completed. Though the process is still largely manual, it is now possible to efficiently render a QUIC plume in a DIRSIG scene. The remainder of the task, scheduled for completion in December 2006, will fully automate this rendering process.
