Developing an Online GIS Repository for <strong>Permafrost</strong> Data<br />

Christopher W. Helm<br />

(University of Colorado, Boulder, National Snow and Ice Data Center)<br />

Abstract: Much of the permafrost data available over the Internet is hard to retrieve and<br />

difficult to convert into formats that allow users to efficiently distribute and manipulate the data.<br />

I am proposing to promote the development of an online Open Geospatial Consortium (OGC)<br />

Compliant Web Mapping Service (WMS) and Web Feature Service (WFS) that will act as the<br />

prototype for the possible creation of a long-term site for housing permafrost data. The<br />

prototype will be an online tool that allows users to view available permafrost data in a spatial<br />

context, and will allow users of permafrost data to explore, query, and download data in a<br />

number of GIS-compatible formats. Data housed at the National Snow and Ice Data Center<br />

(NSIDC) will be converted and ingested into a spatially compatible database<br />

(PostgreSQL/PostGIS) and served over the Internet via the open source mapping software<br />

MapServer. MapServer allows for the development of user-friendly and intuitive mapping<br />

interfaces that take advantage of OGC protocols for sharing data. Being OGC compliant means<br />

that other OGC compliant services can easily integrate data provided by this prototype service<br />

into their own services. It is important that an intuitive interface be developed to enable the<br />

distribution and sharing of permafrost data and to provide a place for those searching for, and<br />

creating, such data to have a convenient place to share information.<br />

This Web Interface will be developed as a prototype to be showcased at the Asian<br />

Conference on <strong>Permafrost</strong>. It is the hope of the author that by attending the conference users of<br />

permafrost data will contribute important feedback on the feasibility and need for such a utility.<br />

The major benefit for the author to attend the Asian Conference on <strong>Permafrost</strong> is the prospect<br />

that more scientists will become interested in such a site and may be willing to contribute to the<br />

development of such a service.<br />

To the knowledge of the author, this interface is the first GIS web-based application that<br />

integrates permafrost data from the Frozen Ground Data Center (FGDC) at NSIDC. This<br />

conference is an excellent opportunity to support the Frozen Ground Data Center, while<br />

promoting GIS applications and the distribution of permafrost data.<br />
