Weather-Enabled GIS Enhances Public Safety

Integrating and Viewing GIS-Converted Weather Data

Meteorlogix placed weather sensors throughout the metro area to gather and transmit live weather data every two seconds to MxInsight MetroWatch network clients.

MxInsight Analyst, an extension for ArcView 3.2, provides a menu and tools for integrating and viewing GIS-converted weather data from the Meteorlogix data stream and the Orlando weather network to assist in hazard analysis. Emergency services personnel can determine if and when severe weather might impact emergency response plans by adding Doppler weather radar and severe storm tracking information directly into the CATS-ArcView display. In addition, the severe weather events most likely to affect the Orlando area--hurricanes, severe thunderstorms, often with heavy rain, and tornadoes--can be overlaid onto a detailed map of the City of Orlando and used to determine, for example, the precise location of a particularly dangerous thunderstorm cell.

Real-Time Severe Weather Alerts

City departments need to be alerted to severe weather situations so that they can provide quick and accurate response. MxInsight MetroWatch provides real-time alerts of severe weather conditions for more accurate decision making. These timely alerts allow public safety professionals to proactively plan for and act to appropriately handle a severe weather situation--not merely react.

Urban Hydrologic Analysis

Precise knowledge of rainfall coverage and amounts is necessary to better manage urban watersheds. Historical data is important in hydrologic planning and real-time, highly localized rainfall data is needed for flash flood response and management. MxInsight MetroWatch provides unique rainfall estimates derived from radar in addition to real-time rain monitoring from conventional rain gauges.

Results

Implementation of the City of Orlando MxInsight MetroWatch system began in January 2002 and was completed in the summer of 2002. The City of Orlando is now positioned to dramatically improve public safety responsiveness to severe weather situations, biohazards, and chemical threats.

Although it is still early to accurately assess what the long-term results will be, early feedback from the City of Orlando is positive. "We are always looking to make Orlando a safer city," says Greg Gentleman, administrative officer, Orlando Fire Department. "The ability to display and analyze national weather data plus real-time weather observations from numerous points across the City makes it easier for us to make more informed decisions in order to better protect the public."
