There are many free and subscription based Web map services that GeoLynx EOC can consume directly. For example, the Geography Network is a global network of geographic information users and providers. It provides the infrastructure needed to support the sharing of geographic information among data providers, service providers, and users around the world. Through the Geography Network, GeoLynx EOC can access many types of live dynamic maps such as natural hazards like earthquakes, tsunamis, and volcanoes and other types of hazards detected using the US Defense Meteorological Satellite program including fires, floods, hurricanes, and cyclones. ESRI ArcWeb Services also provides fee based Web map services that GeoLynx EOC can directly display, including weather data from commercial Web service providers.
