Past Initiatives

HDWG Groundwater IE



The GW IE was designed to: (1) test the use of both WaterML 2 and Groundwater ML (GWML) with the SOS and WFS OGC web services, respectively, (2) test compatibility with industry software clients, and (3) to facilitate sharing of massive volumes of sensor-based water level observations and related water-well features across the Canada and USA border.

Geospatial Fusion Testbed

Testbed. The 2000 Geospatial Fusion Testbed addressed standard ways of "fusing" disparate kinds of data into one spatial framework. Such data include text with embedded place names as well as video, sound, and photos whose metadata refer to "place." Through Geospatial Fusion, they can be geo-indexed, integrated with other spatial data, and shared across the Internet. The Testbed mainly addressed text, but OGC's specifications will accommodate the other kinds of data.

OGC Web Services, Phase 6

OGC’s Interoperability Program is a global, hands-on and collaborative prototyping program designed to rapidly develop, test and deliver proven candidate specifications into OGC’s Specification Program, where they are formalized for public release. In OGC’s Interoperability Initiatives, an international team of technology providers’ work together to solve specific geo-processing interoperability problems posed by the initiative’s sponsoring organizations.

Civil Works Technology Insertion, Phase 1

Technology Insertion Project. The CTI Project, sponsored by the US Army Corps of Engineers, Engineer Research and Development Center (ERDC), integrated multiple map servers, including nodes at the Corps' Mississippi Valley Division and the New Orleans District Office. Insertion Projects focus on expanding an organization’s interoperability capacity by laying the groundwork for open implementations.


The OGC "Geo-interface for Atmosphere, Land, Earth, and Ocean netCDF" (GALEON) Interoperability Experiment supports open access to atmospheric and oceanographic modeling and simulation outputs.

GALEON Phase I completed in 2007. GALEON Phase II started shortly after. However, Phase II is currently dormant awaiting the completion of the revision to OGC Web Coverage Service (version 2). Once WCS 2.0 work is completed, GALEON Phase II will restart.

Following is a summary of the Phase 1 activity.

SAA Pilot

The Federal Aviation Administration (FAA) SAA Dissemination OGC Pilot demonstrated the feasibility of automating the dissemination and portrayal of Special Activity Airspace (SAA) information (including updates) to National Airspace System (NAS) stakeholders and other external users via OGC Web Services.

NGA Plugweek

The Open Geospatial Consortium (OGC®) conducted a series of tests that examined the interoperability, suitability and performance of National System for Geospatial-Intelligence (NSG) Profiles provided by the National Geospatial-Intelligence Agency (NGA) of four OGC Standards, Web Map Service (WMS), Web Feature Service (WFS), Web Coverage Service (WCS), and Catalog Service (CAT).  In the study, vendors, users, and other interested parties conducted Technology Integration Experiments (TIEs) and mutually refined clients, services, interfaces and protocols in the context of a hands-on engineeri
