Description

An integral step in the data life cycle (after collection and curating) is providing access and data discovery for others to explore the data. Sharing of data across various computer hardware and software platforms is enabled by tools such as the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) Hydrological Information System (HIS) which stores and manages hydrologic and climate data. This system is growing in use by water scientists globally. At the same time, the Open Geospatial Consortium (OGC) has promulgated standards used within the GIS software industry that are also based on web services technologies for data sharing. Specifically, the Web Feature Services (WFS) standard is an interface standard for allowing requests for geographical features across the web using platform-independent calls. This paper presents the design and development of a WFS that shares HIS data as geographic layers accessible by GIS applications to retrieve data from a HydroServer Lite web platform. The WFS queries data from the server and returns results conforming to another OGC standard, WaterML2. This service oriented architecture completes an essential link between two major standards in geospatial and temporal data management and sharing.
