Geographic information systems (GIS) are mapping tools used to integrate, store, edit, analyze, share, and display geographic information. NOS provides a variety of GIS data products to the coastal management community, including digital shoreline data, hurricane information, and watershed mapping projects. Other GIS tools include Habitat Priority Planner, to identify and prioritize habitat areas for management action; Environmental Sensitivity Index maps, which help assess contamination risk; and data used to characterize coastal zone habitats.
