Extending OGC data services for CEOP science community

Abstract

The geospatial data and service capabilities provided by data servers compliant with the Web service specifications of the Open Geospatial Consortium (OGC) are very important to the members of the science community of the Coordinated Enhanced Observing Period (CEOP) who are familiar with the Open-source Project for a Network Data Access Protocol (OPeNDAP). This paper discusses the implementation of middleware to translate the OPeNDAP and OGC protocols to make OGC-compliant data services available to the CEOP community. At the front end this middleware acts as an OPeNDAP server while at the back end it acts as an OGC WCS client. The middleware is being developed through a phased approach. In the first phase, the OGC Web Coverage Service (WCS) connector was developed. The second phase that we are working on is to develop the OGC Catalog Service for Web (CSW) connector which augments OPeNDAP with the catalog search capability. The optional third phase will develop the OGC Web Feature Service (WFS) connector.
