The Protected Areas Geographic Information System (PAGIS) is a National Oceanic and Atmospheric Administration (NOAA) National Ocean Service (NOS) project designed to assist National Estuarine Research Reserve (NERR) and National Marine Sanctuary (NMS) managers. NOS is providing each reserve and sanctuary with a fully integrated GIS and Internet capability. NOS is compiling key GIS data layers for each protected area (e.g., bathymetry, hydrography, transportation) and providing technical assistance and training in ArcView GIS and ArcView Spatial Analyst to NERR and NMS staff. NOS will also be customizing ArcView GIS to address specific coastal management issues. A MapObjects Internet GIS mapping application to help support and illustrate common research agendas throughout the sanctuaries and reserves will be created.
