As such, they are an important tool for individuals, businesses, communities, and government agencies to understand and deal with flood hazard and flood risk. Improving map accuracy is therefore not an academic question--better maps help everyone. Making and maintaining an accurate flood map is neither simple nor inexpensive. Even after an investment of more than $1 billion to take flood maps into the digital world, only 21 percent of the population has maps that meet or exceed national flood hazard data quality thresholds. Even when floodplains are mapped with high accuracy, land development and natural changes to the landscape or hydrologic systems create the need for continuous map maintenance and updates. Mapping the Zone examines the factors that affect flood map accuracy, assesses the benefits and costs of more accurate flood maps, and recommends ways to improve flood mapping, communication, and management of flood-related data.FloodsUnited StatesMapsFloodplain managementUnited StatesFlood forecastingUnited StatesMapsAerial photography in watershed managementUnited StatesFloodplainsMonitoringUnited StatesMapsFloodsFloodplain managementFlood forecastingAerial photography in watershed managementFloodplainsMonitoring551.48United States.Federal Emergency Management Agency.United States.National Oceanic and Atmospheric Administration.National Research Council (U.S.).Committee on FEMA Flood Maps.MiAaPQMiAaPQMiAaPQBOOK9910969100203321Mapping the zone4359776UNINA
