AB: Snow, ice, and frozen ground impact a significant part of the earth's surface and natural cycles. Geographic information systems (GIS) are frequently used in studying and assessing the influence of environmental conditions on geophysical, ecological, or socioeconomic factors, but researchers, planners, and decision makers wishing to incorporate cryospheric information into GIS studies often must confront issues related to data formats, data accessibility, and data quality. The National Snow and Ice Data Center (NSIDC) is developing a repository of GIS resources that will simplify the process of identifying, obtaining, and incorporating appropriate cryospheric data into GIS studies. The initial thrust of this repository is base maps, georeferenced images, and other data layers that may be used to study interactions of cryospheric elements with the environment. Supportive narratives, in addition to existing metadata, will describe appropriate uses and explain competing products. Some products, such as the sea ice trends, are derived from satellite data, while others, such as the circumpolar soils map, are based on mapping of data from multiple ground-based and remote sensing sources. The repository will contain materials available from NSIDC as well as links to related products available from other sources. NSIDC considers feedback from existing and potential users regarding the goals, content, and structure of this repository an essential component of its development.
