The federal government currently needs information on the country's wetlands, but the process of remapping all National Wetlands Inventory (NWI) maps is costly and time-consuming. This paper presents a nontraditional solution by integrating GIS/remote sensing tools to prioritize NWI map updates. Single date satellite imagery and digital vector data are statistically combined to locate and map areas highly likely to have changed. This approach ensures that mapping resources are used in an optimal way where they are most needed.
