For basic navigation; to guide people quickly and increase efficiency.-need initial population and numbers of people at certain areas at certain times throughout the day. o Allows planners to estimate how many people need to evacuate, etc.-spatial patterns of animal rescue; animals play a huge role in response – some people will not evacuate their houses because they do not want to leave their pets.-Recovery o Debris removal o Re-establishment of services o Return to “normalcy”...
