On designing a fast-deployable 'localized' GIS platform for using 'offline' during post-disaster situation.

Modeling the demand and supply during an absolute catastrophe is a major challenge for any disaster manager. This paper demonstrates implementation of an easily deployable end-to-end system, by which, various situational data can be collected by the stakeholders during any post-disaster circumstances, and a general summarized view can be plotted on crisis map. The proposed Four Tier Hybrid Ad hoc Network Architecture does not require an Internet backbone but can conduct the complete process in 'offline' mode. Periodic Merging of GIS data enriches the quality of the summarized view. Here we have tried to evaluate the system based on some initial results on a dummy challenged network scenario.
