Difference between revisions of "Emergency Shelter Allocation Evaluation"

Revision as of 10:50, 15 December 2012

Introduction

This project demonstrates how to make a spatial decision that determines the best use of monetary resources when further developing the emergency preparedness framework of a community. Spatial allocation decisions often can not be made most efficiently with consideration of only an independent variable, and scenarios often become multi-criteria based. This tutorial will demonstrate how this evaluation can be carried out using only Free and Open-Source Software(FOSS), particularly using the Quantum GIS (1.8.0) package and the GRASS Plugin.

Particularly the scenario that outlines what the objectives are for this tutorial involve the expansion of emergency shelters in Hawaii.
