Use of Geographic Data in Natural Disasters Essay -- Natural Disaster

Missing Figures The use of geographic data in the field of preventing and mitigating natural disasters remains a pioneering activity. However the circulation of the technology is still hindered by many issues such as the difficulty in obtaining the appropriate raw data, the lack of effective graphical user interfaces, the intricacy of predictive models and the expense of digitisation (Carrara et al., 1999). Natural disasters are becoming more frequent around the world, as seen in figure 1, which shows that in 1975 there were approximately 50 disasters reported, compared to approximately 400 being reported in 2010. They are a damaging phenomenon upon the Earth’s citizens and the physical environment, but with the use of geographic data, natural disasters such as floods, earthquakes, cyclone s and landslides can be monitored and mapped to ensure a successful disaster response strategy can be put in place to ensure we can protect people and the environment as much as possible. The success of these strategies depends upon access to real-time spatial information that can be used effectively by the Geomatics Industry, governments, relief agencies among others to provide a quick response to the disaster areas (Herold et al., 2005). Kunkel et al. (1999) suggest that there is strong scientific evidence of an increase in extreme precipitation events in particular regions, whilst water shortages are becoming more apparent in other regions, which indicates that weather driven natural disasters will surely become more frequent, resulting in the use of Geogr... ...97) Managing the natural disasters from space technology inputs.
