With an updated Evacuation Study for each of the 11 regions, Florida has one of the only statewide evacuation studies in the Nation. This session will educate participants on its fundamentals,
including HOW and WHY it was created and its implementation across a variety of planning disciplines. Explanations of the major components of the Evacuation Study, including its complex
evacuation transportation models, statewide coordination, behavioral surveys, and associated behavioral assumptions and advanced GIS modeling tools. Planners will gain a better understanding of the purpose, data and methodology of the Studies and how to implement its findings in their planning documents.

Editor's Notes
Who is responsible for doing what?
This is raw LiDAR, displaying all points, symbolized by elevation. Trees, displayed in red, are higher than surrounding elevations. Building footprints are clearly seen in green. The yellow, rectangular area is a swimming pool. The white areas in the north and east are water, where no data was returned.
In this screen shot, only those points classified as ground are displayed. Note that these points are still symbolized by elevation, but a new ramp has been applied (in other words, the red in the bottom right hand corner isnāt the same height as the red points in the previous slide). From this filtered, bare-earth data, a digital terrain model is created.
