Abstract:
City decision-makers need the ability to integrate timely, accurate weather data into GIS analysis systems. First, one must understand the important relationship of GIS and Weather. GIS allows the user to electronically map and “geo-locate” layers of critical infrastructure such as streets, schools, hospitals, fire and police stations, Government offices, even moving EMS vehicles (fleet management). Other mapped layers could include population demographics, industrial facilities, utilities, etc. Weather events such as severe thunderstorms and high winds can be mapped to show and analyze its impact on infrastructure and incidents. One has to search the tool that provides the facility to place real-time weather observations into a GIS format.
One of these powerful new technologies is GIS, Geographical Information System. GIS combines interactive mapping and spatially related information databases, including real time, continually updating severe weather information. Weather-enabled GIS is critical to homeland security and emergency managers because by combining and sharing this information, analysis and graphic representation speeds understanding of an event and improves the decision making process at all levels of response. For instance by overlaying a projected tornado path onto multiple map layers showing locations of hazardous materials storage sites, streets, schools, hospitals and fire stations, the user can more readily and accurately make decisions such as when and where to deploy emergency teams, what streets to blockade, which streets to assign for evacuation routes, which schools and neighborhoods to evacuate, which hospitals to assign potential casualties. Because he has detailed attributes of the storm’s intensity, speed and direction, he can better assess the potential damages and casualties that might occur. Armed with this information, the user has the tools to be proactive in mitigating the effects of severe weather, resulting in significantly reducing the human, material and financial loss to his city.
