The main goal in developing and deploying Geographic Information Services (GIS) at NOAA's National Climatic Data Center (NCDC) is to provide users with simple access to data archives while integrating new and informative climate products. Users who are presented with data discovery options which flow into detailed product selection maps can search using standard “region finder” tools or gazetteer functions. Each tabbed selection offers steps to help users progress through the systems. A series of additional base map layers have been added to provide companion information. New map services include: Severe Weather Inventory, Local Climatological Data, Divisional Data, Global Summary of the Day, and Normals/Extremes products. As with all of our GIS related products, they are provided using Open Geospatial Committee (OGC) compliant Web Map Service (WMS), Web Feature Service (WFS), and Federal Geographic Data Committee (FGDC) metadata to complement the map viewer. Efforts to provide quality assurance and increased performance include collocation of base maps and stations and Asynchronous JavaScript and XML (AJAX) implementations.
